Embroidery efforts have been made in Xiaoxihu District, Nanjing, Jiangsu Province, and micro-renewal of old urban areas featuring "small scale, gradual progress and courtyard by courtyard" has been implemented.
Micro-renovation and renewal of old blocks

In October, 2022, the Supreme Leader of president sent a congratulatory letter to the 2022 World City Day Global Home Event and the Second Global Conference on Urban Sustainable Development, pointing out that the World City Day Global Home Event adheres to the concept of "Better City, Better Life" and is committed to promoting the sustainable development of global cities, which is of great significance to creating a development pattern of balanced benefits, coordination, tolerance, win-win cooperation and common prosperity.

World Cities Day is the first international day with the theme of cities established by the United Nations, and it is also the first international day initiated by the government of China and widely recognized and supported by the international community. In October this year, at the awarding ceremony of the Global Sustainable City Award (Shanghai Award) and the opening ceremony of the China home event of World City Day 2023, the Shanghai Handbook: A Guide to Urban Sustainable Development in the 21st Century, which was jointly compiled by Shanghai, UN-Habitat and the Bureau of International Exhibitions, was released, and some cases were selected, such as the micro-renovation of Xiaoxihu District in Nanjing, Jiangsu Province, the Community Development Fund in Chengdu, Sichuan Province, and the ecological vitality community in Wan Li Street in Putuo District, Shanghai.

How to slightly transform the old urban areas? How do community funds benefit people’s livelihood? How to add vitality to grassroots governance? Recently, reporters visited Nanjing, Chengdu and Shanghai on the spot.

In the morning, standing on the sunny roof terrace of bask in the quilt, Xu Qingyi looked down and saw the tall and strong loquat tree in the courtyard. "When my old house was rebuilt, the designer rebuilt the terrace according to our requirements and kept the loquat tree I planted when I was a child." As an old neighborhood in Nanjing Xiaoxihu area, 75-year-old Xu Qing praised the renovation here.

Xiaoxihu District, Confucius Temple Street, Qinhuai District, Nanjing, also known as Dayoufang Lane Historical Area, is one of the 22 historical areas identified in the Protection Plan of Nanjing Historical and Cultural City (2010-2020). For a long time in the past, it used to be a crowded and messy shanty town with inconvenient life. There were 810 households with more than 3,000 residents living within an area of less than 5 hectares.

In recent years, Nanjing has carried out a pilot project in Qinhuai District, which is characterized by "small-scale, gradual and courtyard-by-courtyard" micro-renewal of old urban areas. While retaining the memory of the city, it has comprehensively improved the living environment and injected new vitality into the old city. At present, the experience of the renovation of Xiaoxihu District has been popularized in 14 residential renewal projects in the old city of Nanjing.

How to deal with the relationship between protection and development in urban renewal? How to focus on the needs of the people? How to continue the urban context? The reporter went to the Xiaoxihu area to investigate.

Research first

Make it clear that "seeing things, people and life" in the transformation of the old city, and form a "five-party platform" to discuss and build together.

The sunshine spilled into the living room and fell on the body, which was warm. "Brand-new, warm and comfortable, full of happiness …" Xu Qing took the reporter to visit home and said a series of adjectives.

"In the past, the house was next to the house, and the lighting and ventilation in the room were not good, and the related facilities could not keep up." Xu Qing said that although he wants to improve his living conditions, the older he gets, the more difficult he feels about his old house. "I have lived for generations and have feelings."

In 2015, I heard that the relevant departments of Qinhuai District investigated the renovation of the old city in Xiaoxihu area. Xu Qing remembered the scene of all the aborigines moving when some old areas were renovated in the early years, and could not help but worry a little, "Will your old house be lost?"

There have been many explorations in Nanjing to carry out the renovation of the old city. Li Jianbo, director of Qinhuai Branch of Nanjing Planning and Natural Resources Bureau, said that Nanjing has taken the practice of demolishing the old and building a new one in the renewal of old urban areas, which has accelerated urban development and improved people’s livelihood needs, but it has affected the style of the old city to some extent. Efforts have also been made to protect the old city buildings, but commercial development has moved out of the aborigines and there is less fireworks.

"We constantly sum up practical experience and gradually realize that urban renewal and transformation should take into account urban construction and residents’ living needs, and handle the relationship between protection and development." Li Jianbo, who is also the executive deputy director of the Urban Renewal Office of Qinhuai District, said that in 2015, the former Nanjing Planning Bureau and other departments proposed to change "top-down expropriation" to "bottom-up renewal", and made clear the general principle of "seeing things, people and life" in the transformation of the old city, which provided guidance for the renovation of Xiaoxihu District.

How does the idea land? In July, 2015, Nanjing contacted experts and students from three local universities in architecture, planning and other related fields, and went deep into Xiaoxihu area to carry out investigation and research, exploring specific ideas for the renovation of old streets. After comprehensive evaluation, the scheme proposed by Han Dongqing, a professor from the School of Architecture of Southeast University, stood out.

"At that time, we refined the plan according to experts’ opinions, and established a’ five-party platform’ composed of government functional departments, planning and design teams, state-owned enterprise construction platforms, street communities and residents to promote urban renewal in the process of joint construction. Among them, Han Dongqing’s team is responsible for planning and design, and Nanjing Historic City Protection and Construction Group Co., Ltd. (hereinafter referred to as "Nanjing Libao Group") is implemented as a platform for state-owned enterprises. " Li Jianbo said.

Co-construction is inseparable from repeated consultations. "Since 2015, we have only spent four years in preliminary research and demonstration." Li Jianbo, who participated in the renovation of Xiaoxihu area all the way, said, "The first step is to solicit opinions from the masses, which made us feel difficult. For example, there are many property owners in many old houses, some want to move, some want to transform, and some family members still have different opinions on how to transform. "

In October 2017, Qinhuai District organized relevant departments to investigate in other places. The practical exploration of transforming residential courtyards one by one in local old streets and symbiosis between indigenous people and new formats helped them open their minds.

"We have changed the traditional practice of’ concentrating on a period of time and completing the renovation of the whole area at one time’ in the past. After fully listening to the opinions of relevant departments, we decided to adopt the idea of’ small-scale, gradual and courtyard-by-courtyard’ micro-renovation, and accordingly formulated the" Guiding Opinions on the Implementation and Management of the Micro-renovation Planning Scheme for the Historic Section of Xiaoxihu in the South of the Old City ". Li Jianbo said.

According to the guiding opinions, residents who are willing to renovate will be paid by the property owner and given some subsidies by the government, and the residents will discuss the renovation plan with the designers and builders of the "Five-Party Platform"; If you choose to find another house to move and give up the property rights of the old house, you will be compensated according to the policy; If the property rights are reserved and the old houses are leased to the state-owned enterprise to build a platform, the vacated space will be used for public facilities and the introduction of formats to promote the organic renewal of the old streets; If you have not made up your mind about whether to transform, you can wait until the conditions are ripe. "The working mechanism of the’ five-party platform’ has been retained, and planners are resident in the community and can come to the door at any time." Li Jianbo said.

Xu Qing chose the renovation, feeling that he saved money and worry. "During the renovation of the old house, the planners and builders visited many times to listen to opinions. Because my old house is a dangerous building, according to relevant policies, the government has borne 60% of the renovation costs. "

Li Caifeng, who lives in Xiaoxihu District, chose to rent. "The two-story building where my family lives was built in the late Qing Dynasty and the early Republic of China. I have lived here since I was a child." The 70-year-old Tong Nannan described his mother Li Caifeng’s treasure of the old house as "treating it as a treasure". "Whoever accidentally touches a wall will feel distressed."

In October, 2020, considering his advanced age and difficulty in housing renovation, Li Caifeng rented his old house to Nanjing Libao Group for repair and use, and rented a house in a nearby neighborhood with the rent to improve his life in his later years.

One household, one policy

Respect the wishes of residents, carry out refined transformation and optimize facilities.

"Construction started in March 2021, ended in August, and was renovated and moved home in December." Xu Qing still remembers the process of house renovation. "During the renovation, several days are the same, and sometimes we come to see it several times a day."

This 78-square-meter "new home" is full of ingenious design ideas: in order to preserve the old loquat tree, the designer built a patio in front of Xu Qing’s old house. Han Dongqing, who presided over the renovation design of Xu Qingjia’s old house, said: "We use the small space in front of the old house to build a patio centered on old trees, which is light and ventilated."

This ingenious design is more than one in Xu Qingjia’s house. There is only a narrow space more than 30 centimeters wide outside the bedroom. The eaves are carefully designed above to form a small patio, and the green plants are planted at random. A large glass window is installed directly from the eaves of the patio to the floor of the bedroom. People sitting by the bed seem to be in a garden, and the sunshine is comfortable and the landscape looks beautiful.

"The spacing between houses in Xiaoxihu area is very small. We have changed more than 10 drafts of this patio design." Han Dongqing said, "It is necessary to’ open the window to see the scenery’ and be beautiful and generous, and at the same time take into account the needs of residents for ventilation and lighting in their daily lives."

There are two details that make Xu Qing particularly satisfied: one is the small terrace on the second floor of the old house, and the other is the stairs leading to the small terrace.

According to the original plan, the second floor roof of Xu Qingjia retains the appearance style of the old house roof in this area, with a certain slope. However, after hearing Xu Qing’s suggestion that he wanted to have a place to enjoy the cool in summer and dry clothes in winter, the design team carried out the design of "changing the slope to the flat". Nowadays, the small terrace with a roof of 28 square meters is surrounded by guardrails, and tables, chairs and clothes racks are added in the middle, which is safe and practical.

The stairs leading to the small terrace are unique. "According to the layout of the house, the slope from the balcony entrance to the wall root is very steep. If the stairs are laid, each step is 40 cm high. It is neither convenient nor safe for us to go upstairs and downstairs." Xu Qingbian said that he took the reporter’s experience: after the transformation, each floor of the stairs alternately rises from left to right with the middle as the boundary. The height of the steps is more than 20 cm, and it is not tiring to go upstairs and not steep to go downstairs.

The careful design of "one household, one policy" can be seen everywhere in Xiaoxihu area: some houses are small in size, and the designer carefully creates an open kitchen with a foldable sofa bed, which integrates the functions of kitchen, living room and bedroom; Some residents want to increase storage space, and designers use the height of housing space to build storage cabinets; Some residents have raised the problem of poor lighting in houses, and designers have added more windows in a small space according to local conditions … "We have divided Xiaoxihu area into 15 units and 127 implementation courtyards, fully respecting residents’ opinions and carrying out refined transformation according to the principle of one household and one policy." Han Dongqing said.

After the transformation, the old house is repaired as old as before, and the bolts of doors and windows have been repaired according to the original appearance; The wooden stairs that have been damaged for a long time have not been demolished, but are protected by the tread structure of "glass+steel", which is safe and does not lose the sense of history … "I showed the photos after the transformation to my mother who is inconvenient to move. She even said that she did not expect the transformation to be so meticulous and so good." Tong Nannan said.

How about the fine renovation of residential houses and the construction of supporting facilities? Chen Hongrong, a resident of Xiaoxihu District, took the reporter to visit the "Microtube Gallery" near his home: in the space about 1.8 meters wide and 2.4 meters deep below the ground, there are six pipes in four categories, such as optical cable, tap water, building fire water supply and sewage. There are power pipes and rainwater pipes in the two side rooms, and gas pipes are laid along the wall on the ground. "In the past, the faucets were shared, the wires were pulled privately, the alleys were particularly narrow, and there were no fire-fighting facilities. Nowadays, all kinds of facilities are fully equipped, and gas and tap water are directly connected to the home. Our alley residents have lived a modern life. " Chen Hongrong said.

Activation and utilization

Calculate the people’s livelihood account, cultural account and economic account, explore the interaction between culture and economy, and promote the sustainable transformation.

Chen Hongrong set out from home and went to a construction enclosure in a nearby street. "This will be a bathhouse in the future." Chen Hongrong said that although he has bathroom facilities at home, the public bathhouse where he chats while taking a bath is a part of the life of many old Nanjing people, and it is also the fireworks in the old streets.

Revitalize the use of housing space vacated by some residents, and Qinhuai District actively introduces new formats to enrich and improve community services. Walking into the two-story building after the renovation of Tongnan’s old house, you can enjoy the elaborate decoration, listen to soothing music and taste rich food … Here, it has become a restaurant. Wang Qiuwen, the person in charge of investment promotion of Nanjing Libao Group, told reporters about the investment promotion experience: "This house is located at the main entrance of the street. As soon as the lease information was released in 2020, it attracted more than 10 brand organizations at home and abroad to negotiate. Considering the protection of the old house and the inability to disturb the people, we set the direction in the light food restaurant. "

"After comprehensive evaluation, a new brand of local entrepreneurial youth was selected." Wang Qiuwen said, "This entrepreneur lives in the nearby area. For the residents of Xiaoxihu area, there is a human touch between the old and new streets."

Two years ago, Tong Nannan brushed his old house on the short video platform. "My old house has become a online celebrity restaurant. Many old classmates and old neighborhoods contacted me and praised the transformation." Tong Nannan said that she likes the photo wall in the old house best. "The contrast photos before and after the renovation carry memories of my family and also tell tourists the story of the activation and utilization of the old house."

Fan Ning, Chairman of Nanjing Libao Group, introduced that the activation and utilization of old houses and buildings will continue to be promoted, and local efforts will be made to calculate three accounts: first, people’s livelihood accounts to meet the needs of residents’ lives, and old bathhouses, restaurants and other formats will be introduced; The second is a cultural account that conforms to the style of historical blocks and enriches the format of cultural experience projects; The third is the economic account of the overall profit of various formats, ensuring that the renovation of the old city is sustainable and can be promoted.

Strolling around the Xiaoxihu area, the long streets, quaint brick walls and elegant courtyards … In front of us, these renovated old buildings and old houses are radiant, revealing the profound historical and cultural heritage. In the evening, 24-hour bookstores, handicraft workshops, and cultural and creative markets in the area light up one after another.

Qinhuai Lantern Studio, which is renovated and covered with colorful lights, is now one of the most popular punch points in Xiaoxihu area. "Nanjing Libao Group invited me to set up a studio in the area to show and teach more people the Qinhuai lantern making skills that have been passed down for thousands of years. Now, there are many tourists in the studio every day, and some primary and secondary schools also come to carry out intangible cultural experience activities. " Gu Yeliang, the representative inheritor of the national intangible cultural heritage of Qinhuai Lantern Festival, said.

Not far from the studio, it is Xiangluan Square in the center of Xiaoxihu District, which is the site of Xiangluan Temple in Ming Dynasty. Xiangluan Temple has long since disappeared. Designers and builders opened up a 750-square-meter space, rebuilt an arc-shaped red wall and built a square in front of the temple with reference to literature.

Chen Hongrong said that now he often goes to the square to exercise. On holidays, he can watch open-air movies, listen to a series of good shows and visit the Qinhuai Lantern Festival. "Cultural activities are rich and colorful, and we are livable and lively here."

"To calculate the three accounts, we must protect the fireworks and cultural flavor of the old city, and we must also explore the interaction and integration of culture and economy." Fan Ning said, "Creating a rich cultural format does not directly generate economic benefits, but it can attract passengers and boost popularity, and feed back the diversified formats in the area to expand the’ economic account’ and achieve sustainable operation."

In 2022, the total revenue of various formats in Xiaoxihu area reached more than 45 million yuan, which promoted the activation and utilization of old houses, ensured the daily operation of the state-owned enterprise construction platform, and realized the sustainability of the renovation and transformation of the old city.

Common governance and sharing

The "Symbiotic Courtyard" harmonizes neighborhood relations, and the "Shared Courtyard" opens the gate of the courtyard, and both new and old residents have a sense of gain.

In recent years, 73-year-old Chen Hongrong has met young new neighbors.

The courtyard where Chen Hongrong’s family lived originally had five families. The old photos hanging at the door recorded the life scenes at that time: the living space was narrow, cooking had to be supported by gas stoves in the corridor outside the house, and all kinds of sundries were piled up in the public space of the yard. "In the past, the yard environment was poor, and whoever hung more clotheslines and piled up things, things with big sesame seeds could quarrel." Chen Hongrong said.

During the renovation process, Chen Hongrong and another household chose to stay, and the other three households chose to move out. The vacated houses and spaces were partly used to improve the living environment of residents, and some were built into community planners’ studios and cultural and creative shops, and young planners and cultural and creative shop owners moved in.

How do new and old residents live in harmony? Chen Hongrong took out a "Small West Lake Symbiosis Hospital Convention" signed by two households, two new owners and Nanjing Libao Group, which included not only the principled provisions such as "everyone’s affairs should be negotiated together", but also detailed provisions such as taking turns to clean public sanitation and avoid noise in the morning and at night. "The state-owned enterprise construction platform and the street community have proposed to build a’ symbiotic hospital’, and at the same time, we will be guided to discuss and discuss, and everyone’s affairs will be discussed." Chen Hongrong said.

Now, Chen Hongrong will put tables and chairs in the yard almost every morning, make a pot of hot tea and greet visitors. When meeting community planners to take residents to talk about work, or tourists to Wenchuang store to buy products, Mr. Chen always takes the initiative to say hello, and sometimes takes everyone to visit the renovated new house to talk about the history and new life of the old street. "Now, the neighborhood is harmonious and life is comfortable …" Chen Hongrong said as he showed the reporter around. On the windowsill of his room, there are all kinds of green plants provided by Wenchuang Store next door. In the small open space in front of the window sill, Mr. Chen made room for Wenchuang Store to set up tables and chairs and show products to customers.

"Symbiotic courtyard" harmonizes the neighborhood relationship, and "shared courtyard" opens the courtyard door. In the winter afternoon, the reporter came to the home of Liu Guangji, a resident of Xiaoxihu District. Through the hollow flower wall in the backyard, the scenery in the courtyard was unobstructed: pomegranate trees were planted in the north, grapevines in the middle, loquat trees in the south, and chrysanthemums, camellias and Chinese rose flowers were dotted in the middle … Liu, who was pruning, called the reporter into the courtyard. "We are a’ shared courtyard’ specially built by designers. The original dilapidated hollow flower wall was carefully dressed into a hollow flower wall.

"We who grow flowers are afraid that no one will appreciate them." Liu Guangji said with a smile, now several people visit the yard every day. When Epiphyllum is about to bloom, he will hang up a notice board at the door and invite neighbors and tourists to enjoy it. "In the past, my wife and I didn’t go out much, but now I have made many new friends, and friends who love to grow flowers regularly come home to exchange planting experience."

Open the courtyard door, open the heart door. Under the guidance of street communities, the concept of co-governance and sharing is taking root in Xiaoxihu area. During the interview, the reporter saw that many restaurants, pubs, etc. will set aside an open space outside the shop and behind the front yard, and put up several tables and chairs for pedestrians to have a rest and chat.

"There were almost no tourists in the Xiaoxihu area in the past, and the population over 60 years old accounted for a high proportion. Today, in addition to the remaining aborigines, it also attracts many young people to work and live here. " Su Bin, secretary of the Party Working Committee of Confucius Temple Street, said, "To promote the renovation of the old city, we must not only do a good job in physical space transformation, but also improve the level of community governance through joint construction, governance and sharing, so that new and old residents can have a sense of gain and make the old city more vibrant and energetic."

"During the Tenth Five-Year Plan period, Nanjing will transform 605 communities, benefiting 160,000 households. The experience of the renovation of Xiaoxihu District was written into the Measures for Urban Renewal in Nanjing, and it was promoted in 14 residential renewal projects in the old city that Nanjing continued to carry out. " Li Jianbo, who participated in the drafting of Nanjing Urban Renewal Measures, said. (Reporter Yao Xueqing)

CCTV News:The 132nd China Import and Export Fair, the Canton Fair, opened online on October 15th. With the theme of "China Unicom’s domestic and international double circulation", this year’s Canton Fair will give full play to its online advantages, break through the exhibition period restrictions, and optimize and upgrade the platform functions, which is expected to enhance the motivation and confidence for China’s foreign trade innovation and development.

　　　　 According to Hong Kong media reports, SJM Holdings held its annual general meeting on Tuesday (9th). It is reported that there was a minute’s silence for the founder "Gambling King" Stanley Ho, but it did not accept any questions from shareholders. After the meeting, the management met with the media, and the impact of Ho’s death on the company became the focus of questioning.

　　He Chaofeng, the second daughter of Hejia Fannie and Freddie and the chairman of the company, has repeatedly stressed that everyone is reluctant to part with his father’s death, but he quit the management of the company as early as 2018, and the current management has been satisfied with the operation. When asked about the results of the re-election of the company’s directors, she pointed out that the votes were still being counted, but she believed that herself, co-chairman Huo Zhenting, Si Tai Liang Anqi and vice chairman Su Shuhui would remain in office, and that there would be no major changes in the board of directors.

　　In fact, SJM announced that Chairman He Chaofeng was appointed as the authorized representative of the company, effective from June 10th. In addition, the company also announced that Wu Zhicheng was transferred from an executive director to a non-executive director and retired as the operating president and authorized representative, which also took effect on June 10. The company also announced the voting results of the annual general meeting of shareholders, and all resolutions were passed. Including the re-election of He Chaofeng, Huo Zhenting, Liang Anqi and Su Shuhui as executive directors, were all passed by more than 96% of the votes.

　　Asked why the executive director "San Tai" Chen Wanzhen was not present today? He Chaofeng said: "Dr. Chen (Chen Wanzhen) can’t come today."

　　As for the death of the gambling king, will the company apply to the government to postpone the renewal of gambling cards? She said that whether the application for gambling cards should be delayed depends on the arrangement of the Macao government, and the company will cooperate.

　　In addition, the media are also concerned about the operation of Macao’s gambling industry this year. Su Shuhui said that "everyone lost money in the first half of the year", and now it is the worst. In the second half of the year, I hope that Macao’s customs clearance will restore business. He bluntly said, "This year is not very optimistic, and I hope there will be a rebound next year." The turnover so far this year is equal to 1/10 of last year. He Chaofeng added that at present, the number of tables returning to work is half.

　　In addition, when will the company’s new project be opened in Portugal? He Chaofeng said that the project has been completed, but the company did not stop applying for the required business license despite the epidemic, so the leading power lies with the Macao government. She hopes that the project can be opened after the travel restrictions are relaxed.

　　Liang Anqi added that the recruitment of this project has been in progress. This includes recruiting new graduates.

　　Regarding the arrangement of the company’s satellite casino, He Chaofeng said that there is no conflict between the satellite casino and the new project, and it should continue to follow the previous practice.

　　BEIJING, Beijing, May 17 (Zhongqing) Following Beijing, hot cities such as Guangzhou, Shanghai and Shenzhen have successively introduced property market regulation measures for commercial projects. Although the intensity of control is different, it is clear that commercial projects should not be linked to residential properties, and some cities have also explored control methods in architecture and design, trying to reduce the possibility of commercial projects turning to residential uses from the product development end.

　　After Beijing, Shanghai, Shenzhen and other places followed up to regulate the commercial market.

　　On March 26th, Beijing Municipal Commission of Housing and Urban-Rural Development issued a document to regulate the commercial market, saying that "commercial and office projects (hereinafter referred to as commercial projects) should be developed, constructed, sold and used in strict accordance with the planned purposes, and may not be changed to residential purposes without approval", completely changing the rules of the commercial market.

　　The above-mentioned policies in Beijing not only block the channels for individuals to buy projects that have not been built, are under construction or are being sold, but also set strict thresholds for individuals to buy second-hand commercial houses.

　　Four days later, Guangzhou proposed to strengthen the management of commercial real estate projects. "Real estate development enterprise vendors do property, the sales target should be a legal entity; The commercial property purchased by a legal entity shall not be used as a residence, and when it is transferred again, it shall be transferred to the legal entity. "

　　On April 21st, many departments in Chengdu jointly issued the Notice on Further Strengthening the Management of Commercial and Office Construction Projects, requiring commercial and office construction projects to be developed, constructed, sold and used in strict accordance with the nature of planned land and planning permission, and it is strictly forbidden to change them into residential purposes without authorization.

　　On the same day, Shanghai required that the land transfer contract should specify that office land should not be used for apartment-style office projects, and commercial land should not be used for apartment-style hotels without agreement.

　　On May 12th, Shenzhen also issued a document to restrict the transformation of commercial offices. In the next five years, the transformation of commercial offices, R&D buildings into apartments, stealing areas and rebuilding will be strictly restricted. "After the introduction of the New Deal, such facilities will serve more office needs, that is, they are unlikely to serve the needs of housing." Yan Yuejin, research director of the think tank center of Yiju Research Institute, said that this has a negative effect on the subsequent Shenzhen commercial projects.

　　So far, Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu and other cities have implemented control policies for commercial projects. From the perspective of urban types, they are basically concentrated in first-tier cities and some hot-spot second-tier cities.

　　Product design of multi-city document management and control returning to commercial attributes

　　No matter from the length of policy content, release time and follow-up supporting measures, Beijing has the strictest control over commercial projects.

　　"In the more than one month after March 26th, the actual transaction in the commercial market in Beijing fell sharply." Zhang Dawei, chief analyst of Zhongyuan Real Estate, bluntly said that it is the strictest commercial purchase restriction policy in history, which has dealt a significant blow to the overheated commercial market.

　　According to the policy of multi-site business regulation, it is a basic principle not to change it to residential use without authorization. For real estate development enterprises that change commercial real estate projects into residential purposes in violation of the plan, they all take a firm attitude of "once verified and dealt with seriously".

　　On the other hand, there are also differences in the intensity of regulation. Except for Beijing, other cities have not explicitly restricted individual commercial loan purchasers from running projects. Shenzhen, Chengdu and other places focus on product design control at the supply end.

　　For the development enterprises, the minimum division unit of newly-reported commercial projects is strictly regulated as not less than 500 square meters in Beijing, not less than 300 square meters in Guangzhou, and only part of the proportion is required in Shenzhen. In terms of transfer, Beijing and Guangzhou stipulate that purchased commercial properties can be transferred to legal entities and individuals, but Guangzhou has set "additional conditions" for the transfer, that is, individuals can not transfer again until they have obtained the immovable property certificate for two years.

　　Why is it limited? Crack down on speculation and limit the influx of people

　　"The activity of commercial projects is mainly due to the restriction on the purchase of houses and the high-end of houses, so a large number of public buildings are supported in the residential land." Speaking of the heat of the commercial market, Zhang Dawei believes that it has something to do with the increase in population.

　　Zhang Dawei said that in first-tier cities such as Beijing and Shanghai, the demand for permanent residents’ housing is huge. Some projects in the name of commerce, hotels and offices, by dividing property rights, change the use attributes of commercial projects, take "quasi-housing" as a selling point, and play a marginal role in electricity and water use to attract buyers.

　　However, due to the different nature of land use, there are obvious differences between commercial projects and commercial housing. First of all, the property right is 40 or 50 years, and there is no residential facilities (school district houses, etc.), with high residential density and small apartment type; The most important thing is that the house price will be lowered by 50-60% compared with the price of commercial housing in the same region.

　　"Low housing prices and no purchase restrictions are the main reasons for choosing commercial projects." Many interviewees who have purchased commercial projects told the reporter of Zhongxin. com.

　　Why should we regulate the commercial market? "The first is the planning problem. The business that is originally a residential facility has the property of residence, which is contrary to the planning and the related facilities cannot be followed up; The other is the population problem, such as the large population of commercial projects in Beijing and Shenzhen; In addition, due to the low land price of commercial land, developers take land with commercial land but sell it at residential prices, earning extra profits in disguise. " Zhang Dawei said.

　　Hua Zheng, an associate professor in the Department of Land Management, School of Public Administration, Renmin University of China, pointed out in an interview with the media that commercial regulation will ensure that residential houses and commercial offices belong to commercial offices, reduce the customer base of commercial properties, reduce the enthusiasm of developers and investors to run products, and then reduce the premium level of commercial land. "Cracking down on speculation in the commercial market will also limit the disorderly influx of population into big cities to a certain extent".

　　It’s not over! More cities may be planning to standardize the business market.

　　"There are cities that are brewing or starting to set off a new round of blockades ‘ Business changes to residence ’ 、‘ Do change and live ’ The policy tide. " Zhang Dawei predicted that before, the investment demand for buying commercial projects due to residential purchase restriction may face great risks.

　　Yan Yuejin, who predicted that Shenzhen and Shanghai would follow up the regulation of commercial projects, told reporters that in the future, some hot cities will actively follow up the purchase restriction of commercial projects. Although the intensity of control will not be equal to that of Beijing, one thing is certain: "Commercial projects are no longer linked to residential properties."

　　In Yan Yuejin’s view, in terms of policy strength, the measures to directly restrict or prohibit sales represented by Beijing are the most severe, and the control effect is the most obvious; However, the following mainstream model may be to standardize the supply side and actively control product design.

　　"Beijing and Guangzhou will not rule out the formulation of new policies for existing properties, for example, reasonable guidance for some buyers who sell and transfer houses." Some insiders analyzed to reporters. (End)

　　　 Write something unrelated to the evaluation before the evaluation.

　　　 Mr. Fujiko F Buxiong, the author of Doraemon, which I loved most when I was a child, died unfortunately before the cartoon ended, leaving an unresolved ending. Among the numerous supplementary endings of later generations, one of my favorite endings is that the robot cat suddenly got sick one day and didn’t have time to repair it, so it silently bid farewell to Nobita. After a period of decadence and depression without robot cats, Daxiong began to study hard, and returned after graduating from Ph.D., finally being able to repair the robot cats. The first sentence after the robot cat opened its eyes was: "Daxiong, I have been waiting for you for a long time."

　　　　Yes, I have been waiting for you for a long time.

I’ve been waiting for you for a long time, RAZR

　　　 Since the first generation of RAZR”V3, it has been destined to become a classic. Although it began to enter the quagmire of design after V3, it entered the most difficult time. However, from the beginning of the system, the former Motorola began to return strongly, and the former classics finally shone the most brilliantly in generate today. On October 19th, Motorola and Verizon held a press conference, which officially debuted. The thickness of 7.1 mm once again became the focus of attention in the Android market.

RAZR depth evaluation of 7.1mm motorcycle with sharp blade

　　　 RAZR blade series returns again.

Let’s look at the thickness of RAZR.

　　　 When the author got this brand-new RAZR blade, its appearance was completely different from that of that year: Android2.3 system, 4.3-inch qHD resolution Super AMOLED Advanced screen, 1.2GHz dual-core and Cabra back coating. When these elements are combined together, we can see that several years of snow storage has made RAZR Blade have a deeper transformation, and it has become stronger and will become stronger.

7.1 mm unusually amazing thickness

　　　 RAZR, like his nickname "Blade", has an unimaginable fuselage thickness of 7.1 mm. Although this is only the thinnest part of its fuselage, the thickness of most parts of its fuselage is controlled at around 7.3 mm, even this can’t stop Motorola RAZR from becoming one of the thinnest fuselage.

Ultra-thin blade design RAZR

　　　 Although the thickness of Motorola RAZR fuselage is controlled at about 7.3 mm in most places, there is still a large protrusion at the top of its fuselage. This design is mainly because of the camera that supports 1080P full HD camera.

MOTO RAZR

Bottom Mic

　　　 In addition to the 7.1 mm fuselage and 8 megapixel camera, we also found that the configuration of the fuselage interface is also extremely complete. The 3.5 mm interface on the top of the fuselage, the MicroUSB data interface and the video output interface of the mini HDMI are lined up. Of course, because Droid Razr locates the flagship, it also supports WebTop 2.0 extension.

Side Micro-SIM card slot and Micro slot

　
Profile close-up

　　　 Another thing worth noting is that the Droid Razr uses an integrated design, so the MicroSD card slot and the Micro SIM card slot that first appeared on the MOTO machine are set on the side of the fuselage and protected by a dust cover.

Kevlar bulletproof armor on the back

　　　 On the back of the whole fuselage, we can see a layer of material that is neither metal nor plastic. This is our unique secret: Kevlar coating. This layer with a thickness of only 0.3 mm is five times stronger than stainless steel. This time, Motorola introduced Kevlar material into Andorid and became a leader among ultra-thin materials.

Kevlar coating on back

Top blue shark design

　　　 Originally named KEVLAR in English, it is also translated as Kevlar. It is the trade name of an aramid fiber material developed by Dupont Company in the United States. The original name of the material is "poly (p-phenylene terephthalamide)", which plays a great role in the military. It is widely used in anti-missile coating of armored vehicles and tanks. With the progress of science and technology, Kevlar has also achieved good results in civil use. The entire back of Motorola RAZR is coated with Kevlar, which ensures toughness and obtains a very good feel.

Back design

　　　 It is said that the design of Motorola RAZR is inspired by the concept sports car, and the streamlined appearance and super-strong materials have created the glory of this RAZR. Compared with the previous aviation grade aluminum alloy material of V3, this RAZR has gone further in technology.

Nanotechnology SuperAMOLED Advanced Screen

　　　 For now, the attraction of hardware to consumers has far surpassed itself and the charm it brings. Of course, it may not be suitable for this Razr in our hands. After all, the 7.1 mm body and the use of Kevlar bulletproof fiber have a great impact, but it at least shows that hardware configuration plays a vital role in the success of a mobile phone. Therefore, we can see that although Razr has a very distinctive appearance, it is also painstaking in terms of hardware configuration. Although the author has not been in contact with this model for a long time like everyone else, it is easy to summarize the following characteristics for everyone. See if these characteristics can strengthen your determination to buy.

1. Super AMOLED Advanced screen with qHD resolution (expectation index: 7/10)
2. Gorilla scratch-resistant glass (expectation index: 6/10)
3. TiOAMP 4460 1.2 GHz Cortex-Duocore+PowerVR SGX 540 (expectation index: 8/10)
4. LPDDR2 RAM (expectation index: 5/10)
5. Bluetooth 4.0 with BLE+EDR (expectation index: 10/10)
6. Our camera supports 1080P shooting (expectation index: 8/10).

　　　 In short, although Razr has no obvious advantages in hardware configuration, its skill in some details is enough to conquer the demanding requirements of most users. If you don’t believe it, please follow the author’s steps.

Super AMOLED Advanced screen

Corning gorilla scratch-proof glass

　　　 Although qHD(960×540), a special resolution, was first used in the field of Android, and the screen performance of large-screen mobile phones was further improved, but a good breakthrough has not been found in the screen material. However, as the main competitors in the industry,,, and have repeatedly used SLCD, Super AMOLED series, BRAVIA, ASV and IPS to attract the attention of the audience. Consumers also hope that MOTO products can make a breakthrough in the selection of screen materials. TFT, a more traditional technology, obviously no longer meets people’s positioning for high-end smart phones.

Screen display effect

　　　 Therefore, we saw that MOTO finally used a kind of Super AMOLED Advanced on their latest Razr. Although it is the first time for me to hear about this kind of screen, combined with my own feelings and the powerful Internet, I summarized the following characteristics for the majority of netizens.

1. The first AMOLED screen with qHD resolution.

Screen display effect

Although there is no evidence to prove that the screen made of AMOLED material has certain restrictions on the resolution, but look at the previous series of products, the resolution of most AMOLED series screens on the market is 800*480. Although this resolution has not affected the sales of Samsung Galaxy series products, it is somewhat unpleasant for consumers who are constantly pursuing perfection.

　　　 Nowadays, with Razr, the resolution of Samsung’s AMOLED series screen has successfully reached the qHD level, and above Razr, it is pixels per inch with 256ppi. Although this screen is not as delicate as Retina level, it is also extremely top-notch in the current market.

2, more power saving

Super AMOLED Advanced screen

　　　 TFT screen is no longer suitable for the development of the times in terms of response time and thickness, while AMOLED screen is superior to TFT screen in terms of power consumption and color performance because of its self-luminous characteristics. On the Super AMOLED Advanced screen, because the black dots don’t emit light at all, the power consumption is correspondingly much lower.

3: corning gorilla glass encounter AMOLED

Scratch-proof glass is put in the trouser pocket without pressure.

　　　 It is not the first time that Corning Glass has appeared on MOTO’s mobile phone. The previously popular series and Atrix series all used this hard scratch-resistant and brighter screen. But this is the first time that Corning and Super AMOLED series products are combined. We all know that Super AMOLED series products have removed the touch layer in the screen in order to show brighter colors, so that the glass on the screen surface and the LCD panel are directly bonded together. Therefore, the use of Corning glass protects our LCD panel from damage with a hard "shell", and at the same time, because it is no longer necessary to have a film, the advantages of Super AMOLED in bright colors can be displayed more intuitively in front of users.

Brand new TI OMAP4460

TI OMAP 4460 processor

　　　 In order to wholeheartedly create a product that satisfies users, we saw a brand-new SoC from Texas Instruments OMAP4460 on this Razr, and this is the first time that this SoC has appeared on the platform (the highly anticipated Galaxy also uses OMAP4460, but it can only be the second child because of its late release time), so does OMAP4460 have a performance breakthrough compared with the previous OMAP4430 and the powerful Exynos 4210?

It belongs to OMAP4460 with GALAXY Nexus.

Working environment of TI OMAP series products

　　　 First, let’s look at the difference between OMAP4430 and OMAP4460. In fact, OMAP4430 and OMAP4460 both belong to the OMAP4 platform of Texas Instruments, and there is not much difference in technology and architecture. The main difference in performance is that OMAP4430 can only work at the highest frequency of 1GHz, while OMAP4460 can support at the highest frequency of 1.5GHz, which shows that OMAP4460 used on RAZR has been down-converted, but this will not affect our expectations for its performance.

　　　 In addition, the new OMAP4460 also supports 1080P full HD video recording function, so we can see that the words 1080P HD are clearly marked on the camera on the back of the fuselage. At the same time, OMAP4460 also has a dual-channel LP controller, which obviously improves the access efficiency, which is also lacking in other dual-core SoCs.

The problem of fever still needs attention.　

Kevlar coating can accelerate heat dissipation.

　　　　Although OMAP4460 and previous OMAP4430 belong to the category of smaller chip area in the whole dual-core SoC field, their calorific value at work is easier to control compared with other products, but in the actual use of the author, it is found that Droid RAZR has obvious calorific phenomenon, and this experience is also obvious to some extent because of Razr’s ultra-thin body.

GPU main frequency promotion architecture remains unchanged.

TI OMAP4460 adopts SGX540 GPU.

　　　 In addition to the lack of calorific value, the PowerVR SGX540 graphics processing chip integrated in OMAP4460 is another place that the author is not satisfied with. Compared with the POWERV SGX543MP2 and Adreno 220 of Qualcomm, it is somewhat outdated, but fortunately, Texas Instruments has improved the default working frequency of POWERV SGX540 from 200MHz to 300MHz, which has brought about a certain performance improvement.

OMAP4460 is the best in performance testing technology.

　　 　I have explained so much about performance in front of you, so we still can’t test the performance for you. The testing tools are still Antutu and Vellamo testing software. However, before the test, the author also made a statement for everyone: because this ZO channel evaluation is an engineering prototype, the performance can not be completely stable. The test is for reference only, and we will bring you the most accurate evaluation data after receiving the official retail version.

Test details

　
Antutu running score

　　　 Antutu mainly evaluates the comprehensive strength of the whole system, while Velamo pays more attention to the performance of JS and HTML5. Antutu scores 5100 points, while Velamo scores 600+, and the overall performance has reached the top level. Of course, at present, because the machine is still an engineering prototype, the performance is only for your reference, but there is no doubt that RAZR has reached the top level in the current ranks.

Casual little surprise Bluetooth 4.0

　　　 I want to say that the most impressive hardware configuration on Razr is Bluetooth 4.0 technology, so I believe many users will cast a disdainful eye, not to mention that this function has not been mentioned too much. But after understanding the corresponding background, I believe everyone will understand the original. Before introducing Bluetooth 4.0, let’s first understand another term-short range communication.

Bluetooth 4.0

　　　 Remote communication or near-field communication refers to short-distance data communication between devices at the same time. At present, RFID and NFC technologies are well known in this field. At the same time, because the power consumption of short-range communication is very small and most of them have the characteristics of authentication-free pairing, they are favored by Google and gradually spread to its leading position. In our daily life, because NFC chip has passive characteristics, it can be easily deployed on any device (for example, the NFC game launched some time ago took advantage of this characteristic). At the same time, as the predecessor of NFC technology, the popularity of RFID radio frequency chip technology has made NFC a hot topic in distance communication technology, and major manufacturers also hope that this not-so-new technology can bring us another change in interaction mode.

　　　 What does Bluetooth technology have to do with these? Compared with the previous Bluetooth versions, they are really not suitable as the main technology of short-range communication, because the authentication mechanism and slow connection speed of Bluetooth make Bluetooth more suitable for high-speed transmission of point-to-point pairs. However, the latest release of Bluetooth 4.0 seems to want to change this situation, because a technology called BLE has been added to Bluetooth 4.0, which greatly reduces the power consumption of Bluetooth, and at the same time provides a short-range communication feature without verification. Of course, the most important thing is to reduce its connection time to 6ms, which makes Bluetooth 4.0 not at a disadvantage in comparison with NFC technology. In addition, the development time and technical maturity of Bluetooth are far stronger than that of NFC, not to mention its strong support (at present, Macbook Air and Bluetooth 4.0 technology are available). I believe that Bluetooth will become the biggest rival of NFC in the popularization of near-field communication technology in the future.

　　　 We can say that with the addition of Bluetooth 4.0 technology, we also have the ability of short-range communication, and at the same time, with the vigorous promotion of Apple, this technology will get more attention in the future.

New UI for Android2.3.6

　　　 RAZR was released before the well-known 4.0, but the breakthrough in the system is not so obvious except for the industrial design and hardware configuration. Of course, this is mainly because this mobile phone does not use the latest Android 4.0 system, but as long as we use it well, we can really find that we have added a lot of our own unique wisdom to this mobile phone. Let’s take a detailed look at what aspects of MOTO’s wisdom are reflected in.

video

1. A brand-new UI interface

　
UI interface

　
Lots of 3D effects

　　　 It is said that the brand-new UI is actually relative to the traditional Android2.3.5, because the UI used by Droid Razr has actually met with everyone on the licensed product. Simply sum up, this brand-new UI has redesigned the layout of the unlocking interface, the brand-new MOTO Widget, richer custom content and the dynamic effect of light and shadow.

2. Applications that can be grouped

　
primary menu

　
Group function

　　　 Application files are no strangers to the Android system, but the previous folder is more like a desktop plug-in on everyone’s desktop, and the UI that can really group applications is rare. However, MOTO has done a good job in this respect. After entering the menu, we can see many prefabricated groups by clicking on the application grouping in the upper left corner. At the same time, our users can manually modify the groups according to their own needs, which is very helpful for users to manage their massive applications.

3. Trigger trigger mechanism

　
If "the power is lower than 20%", the command "Turn off WIFI due to brightness reduction" will be triggered.

　　　 A and B are associated conditions, and action B will be executed when condition A sets out, which is the principle of the famous "ifttt" website. It seems that MOTO designers have also been inspired by this model, and the trigger function has been added to Motorola RAZR. For example, we want the mobile phone to turn on wifi, turn off cellular data and automatically reduce the brightness of the screen when it is connected to. We can do this by using the smart assistant and following the settings shown below.

MOTOCAST towards the internet cloud

　　　 With the continuous popularization of the concept of cloud, more and more manufacturers begin to produce and release their own transportation equipment and applications, the most influential of which should be just the announcement of iCloud not long ago. Although iOS is ahead, Google has not officially released its own integrated cloud service of opportunity platform, but as a strong advocate of Android system, it has added a personal cloud service of MOTOCAST to its own. With this service, we can turn our own into Razr cloud, making the mobile phone pass WiFi or access multimedia files in the computer.

MOTOCAST

　
There is MOTOCAST in the music photo.

　
MOTOCAST requires simple registration and installation.

　　　 Different from iCloud, MOTOCAST is a personal cloud application, and all functions will not go into a third-party server, but will be transmitted between personal devices. Whether it’s PC, MAC or mobile phone, MOTOCAST can synchronize all your services together, which is very convenient.

　
Wireless AP function

　
Third party software

　　　 At the same time, RAZR also supports WIFI and 3G networks. It is also very comfortable to browse the web through this 4.3-inch big screen, and there is no pressure on web browsing. At the same time, the machine supports wireless AP function, and it can turn the mobile phone into a wireless hotspot to share the Internet with other devices.

Take 1080P video

　　　　Maybe it’s just a technical problem that PCB can be compressed to 7.1mm.. At that time, it was very difficult to compress the camera to a thickness of 7.1 mm. After all, for me, the precision equipment composed of multiple lenses can’t be too thin, so the 8 megapixel camera is a bit prominent, which makes the whole machine feel a bit like a hammerhead shark.

8 megapixel camera

　　　 RAZR has a built-in 8 megapixel camera, which supports 1080P video recording. Let’s take a look at the photo proofs first. The haze in Beijing these days is very serious, which also affects the whole display effect to some extent. But it doesn’t matter, you can still feel the sharpness of RAZR’s photos from the proofs, and the imaging is very clear and the function is quite good.

　　　　In addition, we released a 720P (Due to the engineering prototype, there is a temporary problem with 1080P.) video recording samples, everyone can click on the picture.

Click the picture to download.

The blade is still sharp, RAZR is back.

Available:

space available

　　　 I believe no one wants to buy one and install a memory card to use it, so most of the current flagships have built-in capacity. In the official parameters, I see the combination of RAM and 16GB ROM memory, and the user’s disposable capacity is 11.5GB. However, the project and its display are 8GB of space, and basically there is no problem in putting photos and videos.

Standby:

　　　 RAZR has a built-in 1750 mAh battery.However, in order to pursue the ultimate thin and light battery, it is non-detachable., thus affecting the usability to some extent. Specific standby time The author used this product for three hours, and after heavy use, the power dropped by 40%. Therefore, it is estimated that the standby time is about two days. Of course, we will not see the specific test until the retail version is launched.

Time to market:

　　　In November, it is still uncertain.

Bootloader：

　　 Locking, which is said to be a compromise made at the request of operators, is still inconclusive.

Andorid4.0：

　　　Many people ask the author this question, but the official has not given any answer. According to a large number of recent mobile phone upgrades, Android4.0 can definitely be upgraded, but the specific time depends on Motorola’s official statement.

Motorola RAZR

Seven years later, the blade is still sharp.

　　　 In the past seven years, since the first RAZR mobile phone V3, Motorola has had a low ebb and confusion, but it finally survived. When this model uses Kevlar coating, 7.1 mm thickness, 1.2GHz, qHD Super AMOLED screen and Android2.3.6 system, we see that RAZR is re-energized. The blade is still sharp, and we didn’t wait in vain.

　　　　

　　　

Bai Shuangxia is exactly 40 years old this year. She is a supervisor of Jianbei Squadron of Shijiazhuang Digital Urban Management Chang ‘an District Supervision Brigade. She has a slim appearance. Over the years, she has always had a special hobby of "donating blood". Since 2008, she has insisted on voluntary blood donation every year, which lasts for eight years. During an accidental blood donation in 2010, Bai Shuangxia and her lover filled out a voluntary donation of hematopoietic stem cells. She said that at that time, this volunteer letter was not filled in at will, and she felt that she was filling in a responsibility.

Everyone should be familiar with blood donation, but it may be rare to donate hematopoietic stem cells, because the probability of non-blood relationship is only one in ten thousand to one in ten thousand, and the probability of successful blood matching is very low. In March, Bai Shuangxia received a phone call from the Red Cross, saying that a patient had successfully matched her. Bai Shuangxia immediately told the news to her lover and his 15-year-old son. A strange phone call made Bai Shuangxia’s wish buried in her heart come true.

From then on, Bai Shuangxia began to exercise every day to ensure adequate sleep, and her favorite spicy food was also far away. She hoped that her body could be kept in the best condition to better help patients. In her heart, she would do her best to help boys through life difficulties. Bai Shuangxia is the 288th successful donation of hematopoietic stem cells in Hebei Province and the 8th in Shijiazhuang this year. Speaking of donating hematopoietic stem cells, Bai Shuangxia said that she was also influenced by her lover. Now, even her son Xiaobai is infected by his mother’s actions. "When I reach the age, I will also donate blood and register as a volunteer for hematopoietic stem cell donation." Before the bed, her son solemnly and Bai Shuangxia said.

Nowadays, more and more people are paying attention to this great public welfare undertaking, and more healthy people of school age, especially young people, have actively joined the team of donating hematopoietic stem cells, offering "seeds of life" to patients with hematological diseases and helping them get a new life. Life is more meaningful because of the selflessness of donors. They are admirable. Let’s say thank you to this brave, selfless and kind "most beautiful supervisor"!

　　From July 13th to September 26th, National Cultural Heritage Administration Underwater Cultural Heritage Protection Center, Liaoning Provincial Institute of Cultural Relics and Archaeology, and Dalian Institute of Cultural Relics and Archaeology jointly conducted an archaeological investigation on the wreckage of an iron sunken ship in Dalian waters, and confirmed that the ship was a far-off ship sunk by Beiyang Navy in the Sino-Japanese War of 1894-1895. This is another major achievement in underwater archaeology in China after Zhiyuan Ship. After the news was released, it triggered a heated discussion in society. On September 28th, the staff who participated in the archaeology gave more details about the sunken ship passing through the distant ship in the Sino-Japanese War in Dalian waters discovered by the underwater archaeological team.

　　Disappeared for a hundred years, the sinking ship appeared in Dalian waters.

　　The ship that disappeared for more than 100 years was found. Recently, the news released by National Cultural Heritage Administration triggered a hot discussion among netizens. Jingyuan Ship was an important warship of Beiyang Navy in the late Qing Dynasty, which was sunk by the Japanese in the Sino-Japanese War of 1894-1895, and its whereabouts were unknown for more than a century.

　　In the summer of 2014, an underwater archaeological team found the remains of an iron sunken ship in the south sea area of Laorenshi, Heidao, Zhuanghe, Dalian, Liaoning Province based on data clues and magnetometer geophysical data, and speculated that it was a passing ship, but it lacked decisive evidence. Therefore, from July 13th to September 26th this year, National Cultural Heritage Administration Underwater Cultural Heritage Protection Center, Liaoning Provincial Institute of Cultural Relics and Archaeology, and Dalian Institute of Cultural Relics and Archaeology jointly conducted an archaeological investigation on the iron wreck in Dalian waters, and confirmed that the remains of this ship were the Jing Yuan ship of Beiyang Navy.

　　On September 28th, Zhou Chunshui, the leader of National Cultural Heritage Administration Underwater Cultural Heritage Protection Center who participated in the underwater archaeology of the long-distance ship, wrote in official website, National Cultural Heritage Administration that the water depth of the site area was about 10 meters, and the visibility was poor, and the visibility was less than half a meter for a long time during the archaeological period. To this end, the investigation has increased the investment in geophysical exploration technology, and used many technologies such as multi-beam sea survey, three-dimensional imaging and differential positioning.

　　After a hundred years, the name of the ship is still hanging on the side of the ship

　　Zhou Chunshui and others said that this underwater archaeological investigation is divided into two stages. The main goal of the first stage is to search, locate and evaluate the sinking situation. The underwater archaeological team used equipment to collect relic data, and through data comparison and file analysis, combined with diving exploration, searched, found and confirmed the exact position of the passing ship, and found the ring protective armor belt "Tiejiabao" which can mark its identity. At the same time, according to the attitude and inclination of the hull, the hull should be inverted.

　　The goal of the second stage is to partially clean up, so as to confirm the identity of the sunken ship and find out the preservation status of the sunken ship. The underwater archaeological team carried out sand pumping operation on the starboard outer wall of the middle and rear section of the hull, and revealed the hull structure on the side one after another, including gangways, portholes, various pipeline facilities, etc., and all the components were in an inverted state, which confirmed the inference that the hull was upside down.

　　In order to determine the identity of the sunken ship, the underwater archaeological team made a special work plan, and finally found the name of the "Jingyuan" ship buried 5.5 meters below the seabed on September 15, and it has been hanging on the outer wall of the ship’s side for more than 100 years. Underwater archaeologists also unearthed a wooden sign with the word "Jingyuan" stamped on it during the site cleaning. Before the end of the work, the archaeological team covered the wooden ship names and backfilled all the extracted hull areas. Finally, zinc blocks are welded along the periphery of Tiejiabao by sacrificing anodes to delay the corrosion of iron ships by seawater.

　　Traces of fire can be seen in some cultural relics coming out of the water.

　　Zhou Chunshui and others introduced that a large number of relics were extracted from the water in this survey, and more than 500 specimens were selected by archaeologists. Among them, the representative cultural relics include: small iron boilers (providing steam power for windlass hoists), diagonal trusses, large transverse ribs, portholes, hatches, armored fort linings and other hull structural facilities, Mao Se rifle bullets, Weiblie revolver bullets, 37mm Hakikkai rapid-fire shells, 47mm Hakikkai shells. In addition, the archaeologists also found 53mm Grusen gun cartridge and 120mm shell primer, both of which are not found in the factory files of Jingyuan Ship. Archaeologists speculate that it should be an emergency weapon and equipment added before the Sino-Japanese War of 1894 to strengthen the firepower of the stern.

　　Archaeologists also found a "canopy pole" used to hang a sunshade. The wood was covered with fire marks and almost carbonized, which confirmed the theory that Jingyuan ship was hit and caught fire in the naval battle. At the bow of the ship, archaeologists found some hookahs, mahjong tiles, mazars, oil lamps, wooden pots, shoes soles and other items. According to reports, this place is the living quarters of junior soldiers.

　　Archaeologists have found many bullets of Mao Se rifles in the bow area of Jingyuan Ship. It is speculated that this may indicate that at the beginning of the naval battle, the soldiers of Jingyuan Ship had plans to board Japanese warships with guns.

　　"The underwater archaeological achievements of the remote ship have extremely important historical and scientific value for the study of the history of the Sino-Japanese War, the history of the navy and the history of ships. The discovery of some investigation objects provides a new understanding for the research work, such as ‘ Jingyuan ’ The nameplate is the nameplate of the Beiyang Navy warship discovered for the first time, and its material, technology and installation method are also clear for the first time. " Zhou Chunshui and others introduced.

　　conversation

　　Archaeologist: The soldiers who passed the distant ship were heroes who fought to the last minute.

　　Yu Haiming, an underwater archaeologist from Dalian Institute of Cultural Relics and Archaeology, participated in the underwater archaeology of the remote ship. On the 28th, he told the Beijing Youth Daily reporter that the most crucial evidence to prove the true identity of the remote ship — — The "Jingyuan" nameplate was discovered before a typhoon, when archaeology had come to an end. "This is the most shocking moment in the whole archaeological process."

　　Beiqing Daily: How did you participate in this underwater archaeology?

　　Yu Haiming: I completed the training of underwater archaeology from May to June this year, because the sunken warship in this investigation was on Zhuanghe side of Dalian, so I was invited by National Cultural Heritage Administration Underwater Cultural Heritage Protection Center to participate in the investigation of the sunken ship passing through the distant ship in this Sino-Japanese War. I came to the archaeological site of Jingyuan Ship in early July and participated in the follow-up archaeological investigation.

　　Beiqing Daily: You said that your views on Beiyang Navy have changed through this archaeological investigation?

　　Yu Haiming: In the past, we might think that Beiyang Navy was influenced by the Qing Dynasty and had many corruption problems, which led to the defeat of Beiyang Navy in the Sino-Japanese War. Many people who participated in the underwater archaeology this time are very familiar with the history of Beiyang Navy. Every day, everyone works and lives together, and the topic of conversation is Beiyang Navy. They will also take out old photos and materials, and analyze each other together. I feel that my previous views may be misunderstood.

　　It can be seen that Beiyang Navy has been affected by corruption, but the officers and men of Beiyang Navy are indeed heroes. Not only did they fight to the last minute after crossing the distant ship, but in some diaries left by the Japanese army, they also admired the spirit of Beiyang Navy in fighting to the end. A large number of Beiyang Navy officers died in battle or committed suicide.

　　Beiqing Daily: What impressed you the most in this survey?

　　Yu Haiming: What impressed me the most was when the word "Jingyuan" was discovered in the later period of archaeology. The typhoon was coming soon that day. At 6 o’clock in the morning, an archaeological teacher went into the water to investigate. He first photographed the word "far" passing by a distant ship. At that time, the wind and waves were already very heavy, so we asked him to get out of the water quickly. Then everyone looked at the instrument and basically confirmed that the sunken ship must have passed by a distant ship. Later, we successfully found the word "Jing" with gold on it, and everyone was very excited. The identity of Jing Yuan Ship was confirmed like this.

　　Beiqing Daily: How was the wooden sign with the word "Jingyuan" discovered?

　　Yu Haiming: The’ re’ was drawn when pumping sand. There are many things like shells in the pumped sand. During sorting, we found this’ re’ in it. Because when the distant ship sinks, it carries a lot of coal, and these cinders will dye some wooden cultural relics black. This’re like this. At first, I couldn’t see what it was, but I could vaguely see the word "Jing". Then I took this’re "and went to the team leader. According to the experience, the team leader judged that it might be the word "Jingyuan". Later, through some processing, the word "Jingyuan" appeared.

　　Beiqing Daily: What impressed you about the cultural relics coming out of the water?

　　Yu Haiming: Some teachers are very familiar with Beiyang Navy. I found a 120 mm shell primer when sorting cultural relics. I don’t know much about this cultural relic, but one teacher was very excited. He said that this kind of shell itself was not recorded in the equipment of Jingyuan Ship, and it was suspected that it was specially added to prepare for the Sino-Japanese War. It can be seen that Beiyang Navy had actively prepared its combat effectiveness before the war. In addition, unlike some previous legends, we found some hookahs in archaeology, but we didn’t find any big hookahs. The hookahs are normal when sailing on the sea, and we know that we need such a pastime when sailing. This is inconsistent with the previous statement that some Beiyang Navy officers smoked opium.

　　memory

　　The distant ship is a distant ship.

　　Jingyuan Ship is one of the important warships of China Beiyang Navy in Qing Dynasty. It was built by German Vulcan Shipyard and launched on January 3, 1887. It has a length of 82.4 meters (waterline), a width of about 12 meters and a speed of 15.5 knots. Its main weapons include Krupp 210 mm, 2 caliber guns, 2 150 mm caliber guns and 4 torpedo tubes.

　　Jing Yuan Ship returned to China at the end of 1887, and at that time, as the current ship of Zhiyuan Ship, he was incorporated into Beiyang Navy. Deng Shichang and Lin Yongsheng, the famous generals, respectively served as the duct tape (captains) of the two ships. On September 17th, 1894, the Sino-Japanese Sino-Japanese Sino-Japanese War of 1894 broke out in Dadonggou in the northern part of the Yellow Sea. The officers and men of Beiyang Navy fought bravely against Japan, and the Qing army lost four warships in this battle, namely Yang Wei, Chaoyong, Zhiyuan and Jingyuan.

　　In the battle, Zhiyuan and Jingyuan, under the leadership of Deng Shichang and Lin Yongsheng, fought bravely to kill the enemy, but unfortunately they sank successively. Among them, the distant ship was besieged by four Japanese ships, namely Yoshino, Takachiho, Akinzhou and Nobukuro. The officers and men of the whole ship, led by Lin Yongsheng, took up the battle bravely and never raised the flag until their death. There are more than 200 officers and men in the whole ship. Except for more than 10 people who swam to the nearby Old Man Stone to survive, most of them sank with the ship.

　　Zhou Chunshui and others wrote that the Sino-Japanese War of 1894-1895 was a landmark historical event in the modern history of East Asia. For the Qing Empire, this war ended the historical process in which Emperor Guangxu, Li Hongzhang and other upper-level rulers in the late Qing Dynasty tried to realize the rich country of Qiang Bing through the Westernization Movement and naval construction, and China slipped into the abyss of being poor and weak and being trampled upon by others. For the Japanese side, it became famous in the world after the decisive battle and World War I, and finally it was possible to re-examine China as a victor, thus fueling its ambition of conquering China and dominating East Asia. This edition/reporter Qu Chang

　　Beijing, January 30th, 2007 (Reporter Chang Yafei of the Central Television Station) Recently, there was a picture circulating on the Internet: the central government required "returning home from a low-risk area with a green code", but in the province, it became "negative proof of nucleic acid test", in the city, it became "home isolation", in the town, it became "nucleic acid proof+centralized isolation+home isolation", and in the village, it became "please leave gracefully". The reporter’s interview and investigation found that although this picture on the Internet has deductive elements, it is also a reflection of the facts at the grassroots level. Especially in some places, the epidemic prevention policy is "overweight" or even "one size fits all".

　　On January 27th, at the press conference of the joint prevention and control mechanism in the State Council, Zhao Chenxin, secretary-general and spokesman of the National Development and Reform Commission, and Zeng Yixin, deputy director of National Health Commission, proposed that all localities should not be allowed and do not want to make "one size fits all" treatment when implementing the relevant policies formulated by the state for returning home for the New Year, and should not block people from traveling and returning home, but should give more protection and convenience to the people. What problems did the "Spring Festival returnees" encounter? Why is the "return home policy" being "overweight" in implementation?

　　National Health Commission recently issued the Notice on Printing and Distributing the Work Plan of COVID-19 Epidemic Prevention and Control in Rural Areas in Winter and Spring (hereinafter referred to as the Notice). The "Notice" clarifies that returnees need to return home with a negative result of effective nucleic acid test within 7 days, and implement home health monitoring for 14 days after returning home, during which they will not gather or flow, and carry out nucleic acid testing every 7 days. On January 14th, Xiao Li returned to a low-risk area in Benxi City, Liaoning Province from nangang district, a low-risk area in Harbin, with a negative report of nucleic acid test. When he returned to the village, he was asked to stay at home for 7 days.

　　Xiao Li told reporters: "Normally, those who return home from low-risk areas and have negative reports of nucleic acid testing can move at home normally without isolation. However, our village said that according to the superior’s opinion, I was still quarantined at home for 7 days. However, after the expiration of 7 days of isolation, no one gave me a nucleic acid test, and there were no measures and guarantees during the isolation process. In fact, it was a mere formality. "

　　Xiao Li said that because of the recurrence of the epidemic in Heilongjiang Province, his colleague Xiao Zhang returned to a low-risk area in his hometown of Hubei for 10 days and was isolated in his hometown. He said: "He had already returned home for about 10 days, and there were sporadic cases in Heilongjiang, so the local government asked them to concentrate on isolation again. From the day he came home, he was not released until 14 days after the quarantine expired. Not all of Hubei is like this, but only some parts of Hubei, such as a certain district or a certain township. This is actually the grassroots blindly pursuing prevention and control effects in the process of prevention and control without considering the actual situation. "

　　Mr. Wang from Shanghai recently returned his high-speed train ticket to his hometown in Jiaozuo, Henan. He said that in mid-January, he paid attention to his hometown’s policy of returning home. He learned from the neighborhood Committee that people returning from low-risk areas only need to provide proof of nucleic acid testing within 7 days and then monitor their health at home. He also took the initiative to declare his trip to the neighborhood Committee. But I didn’t expect that the feedback policy of the neighborhood Committee changed two days later: when he returned from Shanghai, he needed to be isolated at his own expense.

　　Mr. Wang said: "My mother called me and said that people in the community came to tell me that if I went back, I would go to the designated hotel for 14 days at my own expense. There is no point in going back like this, because the annual leave is only seven days. This is a soft way to let you not come back. "

　　Ms. Zhou from Anqing City, Anhui Province told the Voice of China reporter that she had planned to go back from Shanghai to visit her grandmother with a cerebral infarction during the Spring Festival, but because the community where her hometown is located requires that she be isolated at home for 14 days and have a nucleic acid test every seven days. Ms. Zhou calculated that the second nucleic acid test after returning home coincided with the date of the doctoral examination, and the neighborhood Committee stressed that the date of nucleic acid could not be revised, so she had to stay in Shanghai.

　　"Even if the nucleic acid testing, why can’t we reschedule? Wouldn’t it be nice to advance or postpone one day? But the people in the neighborhood Committee kept saying ‘ No ’ . In the process of talking to the staff of the (neighborhood) Committee, I found it hard to accept what she said. She said, ‘ I don’t care if you are low-risk or what kind of risk, as long as you come to us, that’s it. ’” Ms. Zhou said.

　　Requirements of returning home for epidemic prevention and control in Anqing City, Anhui Province

　　The "overweight" epidemic prevention policy has also been corrected in some places.

　　On January 24th, a village in Linxi County, Xingtai, Hebei Province issued a notice forbidding villagers working outside to go home for the New Year. After being reported by the media, the village secretary said that there was something wrong with the statement of the notice, but he just hoped that the villagers outside would try not to go home and had corrected the notice. Some netizens also reported that in Taocheng District, Hengshui City, Hebei Province, residents’ committees or property requirements, if they have to return to Hengshui under special circumstances, need to report to the community residents’ committees for registration in advance. After the personnel arrive, they will be isolated for 14 days at their own expense. After media reports, residents’ committee staff said that they had received orders from their superiors to cancel the notice. At present, the requirement is to carry out nucleic acid testing twice within 3 days after returning home, and to monitor the physical condition at home during this period, and not to go out unless necessary.

　　Regarding the deformation of the policy of returning home during the Spring Festival in some areas, Yang Hongshan, a professor at the School of Public Administration of Renmin University of China, told the Voice of China reporter that this is a manifestation of insufficient refined management in some places. He said: "The relationship between epidemic prevention and control, local resumption of production and normal production and living order is actually a parallel relationship, not a one-way choice relationship. Therefore, we can see that in today’s local epidemic situation, maybe our place needs to take care of all aspects. Simply considering only one factor and pursuing absolute safety or absolute self-exemption may also be a manifestation of insufficient initiative and meticulous management in some places. In the process of operation, the basic top-down epidemic prevention and control policies and related laws and regulations are sometimes ignored by grassroots governments. "

　　Yang Hongshan believes that it is necessary to attract the attention of local governments through media publicity and reports, so as to urge them to take corresponding measures in time to stop the "overweight" epidemic prevention and control behavior. Local governments should adopt differentiated management by regions and levels, and pay more attention to "embroidery" and human feelings.

　　"Today, in the face of big data, there is also a collaborative management mechanism between different regions. It is necessary to take the clues of the epidemic itself as the guide, and adopt refined prevention and control measures for local and sporadic epidemics. In the case of complete control, just for the convenience of one’s own work, regardless of the convenience of the other party, and completely ignoring the interests and rights of the other party, it is actually a bit simple and rude, and it is also a manifestation of not taking measures according to people’s policies in local governance. The more you are in the grass-roots governance, the more you face the vivid reality, and the more you know all kinds of differentiated situations. In fact, in the process of grassroots governance, it is more necessary to consider the human touch. " Yang Hongshan said.

Special feature of 1905 film network　First, the most crowded May 1st file in history, waiting for 13 new films to be released together.

　

After the "involution", 520 also released a number of films, quietly forming a new schedule.

　

"520" and "521" as advertising language make May 20th and 21st a festival about love. With festivals, there is also a movie schedule. The 520 files can be traced back to 2018. On May 20th, that week, it won over 100 million box office, which was the highest achievement in the single-day box office of the film. In the end, the cumulative box office of the film won 900 million.

However, this schedule has not formed a stable situation, and it has been in a gap for two years after 18 years.

　

This year’s 520 stalls were originally set up by the joint leadership of My Love on May 20th and May 21st. The overall tonality of My Love is in line with the atmosphere of "520", but "Fast 9" is coming, and many people in the industry speculate that My Love’s film is also the first to plan to release it on May 1 due to various competitive considerations.

　

When My Love left 520, he made room for other films.

　

Up to now, except Fast & Furious 9, a total of six new films will be released in 520 files: Chasing the Ball, The Love I haven’t finished talking about, and all of them are love movies.

This year’s sunset on May 20th and 21st is in the film release period on Thursday and Friday, and it is the first time that many new love films have been released in this festival. Will there be any breakthrough in the 520th movie? At the same time, looking at the Valentine’s Day schedule throughout the year, what new atmosphere can we find?

01　

The 520 schedule has taken shape.

Among the 520 romantic films, the number of people who want to see the platform of Cat’s Eye, Taobao Film and Douban is currently ranked comprehensively, and "Deep Love" and "I want us to be together" rank in the top two.

　

What these two films have in common is that they are adapted from online literature, and the original works have a certain popularity and audience base.

　

"Deep Love" is adapted from Tianya literature’s popular work "Shenzhen, I don’t have the courage to say love again". This article ranks first in the click-through rate of Tianya emotional column in 2014, telling the "deep drift" love story between young men and female executives in Shenzhen; "I want us to be together" is adapted from the 2013 Douban long post "My girlfriend who has been running for ten years with me will get married tomorrow". The bumpy love story of the protagonists Lu Qinyang and Ling Yiyao since high school has caused heated discussion among netizens.

The director of "I want us to be together" once directed the youth love online drama "Hello, Old Times", which was adapted from the original work of Chang ‘an with the same name in August, and the Douban score was as high as 8.7. This time, I once again took the same type of theme, from the screen to the big screen, and the production scale has also been upgraded.

　

The film is produced by the industrial film industry, produced jointly by Alibaba Pictures and Tencent Pictures, and acted as the producer. Desert was also selected as the "Bad Monkey 72 Movie Project" initiated with,, and others. The industry has been expecting the quality of this new love film, but as a new director and actor, it is also necessary to keep a wait-and-see attitude.

In contrast, other incoming romantic films are relatively weak in terms of production volume and the strength of the main lineup. From the perspective of theme selection, Deep Love can be compared with the last film focusing on the group of "drifters". After the film was released in early April, the box office and word-of-mouth performance were not good, and Deep Love hit again this time.

　

In addition, "A little tempted" starring directors, actors and actresses comes from the classic song of the same name. Since 2014, the mode of adapting songs into movies has been continuous, and 2019 can be called a big year. There are three films in a row, and there will be three films in 2020. However, the reputation of these films has dropped almost all the way, so the prospect of "A little tempted" is inevitable.

Judging from the current situation, it is estimated that these romantic films are difficult to have a particularly large performance in the market, and there are no signs of explosion, unless there is a dark horse of word of mouth, or as last year, they break through with marketing and publicity strategies to win.

02　

Fast & Furious 9 assists the one-day box office

There is no doubt that Fast & Furious 9 is definitely the main force of the 520th gear this year. And this festival will definitely add value to the market, and the box office results on May 20th are worthy of attention.

Under the joint promotion of "Living Together in Time and Space", 520 in 2018 coincides with a weekend holiday, with a comprehensive box office of 300 million. In 2019, May 20th is a relatively deserted Monday working day, with no new films released. With the help of the fading popularity, the box office in a single day reached 80 million.

　

In 2020, due to the shutdown of the cinema, 520 became vacant, but this year, with the strong blessing of Fast & Furious 9, the industry also expects that the joint assistance of many domestic romantic films and the zero-point field of Fast 9 on that day will make the single-day box office harvest of this working day exceed 100 million.

This goal may not be difficult to achieve. In 2017, the zero-point box office in China mainland was about 58 million, which broke the zero-point box office record of Fast 7 two years ago. It is very likely that Fast 9 will surpass the figure of 58 million this time. In addition, the festive atmosphere of that day will help boost the box office, so it should not be a problem to break 100 million on the same day in 520.

The Space Potential of Valentine’s Day Schedule

Count the love festivals throughout the year. Apart from 520, there are also Valentine’s Day on February 14th and Chinese Valentine’s Day. The film schedules formed under these festivals are also very different.

　

Because February 14 is generally near the Spring Festival, there are often changes. For example, 2018 falls on the day before New Year’s Eve, and it is impossible to form an effective schedule. This year is just on the third day of the New Year’s Eve, heating up the box office for the Spring Festival. In 2019, after the end of the Spring Festival, four romantic films were released that day.

At that time, "seal it with a kiss" ranked in the top three in terms of first-day screening and box office, followed by leading and waiting for the Spring Festival blockbuster. The final box office of the film was 173 million, of which the first day box office was about 91 million, accounting for about 50%. It can be seen how much Valentine’s Day helps a love movie at the box office.

　

However, the word-of-mouth of "seal it with a kiss" declined the next day due to the reduction in the number of films, and the box office in a single day decreased to more than 15 million, and then gradually declined. The performance of high opening and low walking proves that the key to winning the market for romantic films is still excellent quality and gaining audience recognition.

　

This year’s 520-slot, judging from the overall configuration of romantic films, may not be a big climate, and top foreign films are needed to support the market, but this slot has begun to take shape. The most stable file is still Tanabata. Last year, the box office on Tanabata was as high as 527 million, which set a new record in history and also promoted the resumption of the cinema.

　

On that day, three romantic films landed in the cinema, and "I am waiting for you at the end of time" surpassed 50% of the films, and won 277 million single-day box office, becoming the first box office in the history of Tanabata and the top ten films in the first day of domestic film history.

Tanabata is often in August, which is included in the popular summer file, so the volume level of the films released is relatively large. The formation of the Tanabata market originated in 2015, and the starring actor was released on the day of Tanabata, which set a box office of about 92 million on the first day, more than half of the film’s total box office of 173 million. This data is also very close to seal it with a kiss many years later.

The first day performance of "The Bride Fight" raised the box office on Tanabata Day to 234 million. Since then, the comprehensive box office figures of Tanabata have been 200 million+,and continue to rise.

In 18 years, due to the release of seven new films, the box office climbed to 440 million that day. Although only one new film was released on Tanabata Day in 19 years, it was supported by popularity, which raised the box office of Tanabata to 525 million in one fell swoop.

　

It is worth noting that most of the new films released on Tanabata in recent years are not love movies, and it was not until last year that they changed and ushered in the "Tanabata Special Offer". Although there are still nearly four months before this year’s Tanabata file, there are already love movies customized for Tanabata, so we can look forward to it.

　

The first to grab the spot is the youth film starring the director, the actor and the actress. At the shooting stage, the official announcement was aimed at the release of Tanabata. At present, the movie starring Zifeng Zhang has exceeded 800 million box office, and the main lineup of "Summer Future" is also quite interesting. Can we continue to increase the outbreak of "Zifeng Zhang Year"?

　

In addition, the team’s recent success, this can be a romantic film with the theme of cute pets starring,, and so on. According to sources, the film also plans to join the summer file war, and Tanabata is an option.

The spark of collision between schedule and type should not be underestimated. The 520 files that have become a pattern need to be continuously developed, and the market potential of traditional Qixi files is still great. Especially since this year, the domestic pure love movies that meet the audience in the cinema are not ideal.

　

There is no doubt that the public is eager for love masterpieces. After all, no one wants to see a bad love movie on Valentine’s Day.

This is the 2329th article of Da Yi Xiao Hu.

Up to now, there have been three epidemic outbreaks caused by coronavirus in this century, namely, Severe Acute Respiratory Syndrome (SARS) in 2002-2003, Middle East Respiratory Syndrome (MERS) that began to spread in 2012, and novel coronavirus (COVID-19) that appeared at the end of 2019. China is a country with severe disasters in SARS and this time in novel coronavirus.

First, what is coronavirus?

Coronavirus exists widely in nature. Coronavirus was first isolated from chickens in 1930s, and it was isolated from human nasal wash more than 20 years later by scholars and named B814 virus. Later, scholars made an in-depth study of the virus from its morphology, and found that the envelope of the virus had a spinous process like a corona and a king’s crown, so the coronavirus was named from this. Its natural hosts are mainly vertebrates, and people, cows, pigs, cats and bats are all its natural hosts.

Coronavirus is slightly spherical in shape, with a diameter of 80-160nm. The "crown" on its surface is a fiber process of 12-24nm, and the end of the fiber process is also spherical. The envelope of the virus consists of two layers of lipids, with membrane protein M and fibrillary protein S interspersed between them, and some coronaviruses also have hemagglutinin glycoprotein HE. The interior of the virus is composed of RNA and nucleocapsid protein N, showing a spiral structure.

S protein is the key protein of coronavirus-infected cells, which contains host cell receptor recognition sites and is the main determinant of virus virulence. M protein is the main protein responsible for virus particle assembly. N protein is closely combined with viral RNA, which can protect viral genomic RNA through spiral stacking and encapsulation. At the same time, it can delay the growth of infected cells and make them stay in the division period for a longer time, so that viral RNA can be translated to the greatest extent. HE protein plays a key role in the formation of virus particles.

As far as virus classification is concerned, coronavirus belongs to single-strand positive-strand RNA virus, which indicates that the genetic information of coronavirus is carried by RNA, and the cloned progeny virus has a high mutation rate. After entering the host cell, it directly uses ribosomes in the host cell to produce protein needed for virus replication without transcription. Coronavirus can kill cells, thus damaging various organs, and persistent infection occurs simultaneously with acute infection, mainly attacking gastrointestinal tract, respiratory tract and nervous system.

Second, the coronavirus that humans have fought.

Before SARS, it was thought that only two kinds of coronaviruses could cause human infection. At present, there are seven kinds of coronaviruses that can infect humans, including highly lethal coronaviruses, severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV) and novel coronavirus virus (COVID-19).

The common feature of coronavirus is that it is generally sensitive to heat, and it is moderately stable in a suitable maintenance solution at 4℃, and can be stored for several years at -60℃. With the increase of temperature, the virus resistance decreases. Coronavirus is acid-resistant and alkali-resistant, and sensitive to organic solvents and disinfectants such as alcohol and ether.

The symptoms of coronavirus infection are mostly similar, mainly fever, chills, cough and so on. The main routes of transmission are droplet transmission and contact transmission.

1. SARS coronavirus (SARS-CoV)

Severe acute respiratory syndrome (SARS) was caused by SARS-CoV. By July 2003, it had spread to 24 provinces, autonomous regions, municipalities directly under the Central Government and 28 other countries in China. A total of 8096 clinically diagnosed cases were reported worldwide, and 774 cases died. Nearly 20%~30% of the patients needed mechanical ventilation due to respiratory failure, and the mortality rate was 9.6%. Epidemiology in many provinces and cities showed that the mortality rate increased with age, mostly over 60 years old. Its incubation period is within 2 weeks, usually 2~10 days. The population is generally susceptible and has a strong epidemic degree. The main onset age is 20-30 years old. The source hosts may be bats and civets. The transmission routes are mainly from person to person: droplet transmission in close respiratory tract, aerosol transmission and hand-to-hand contact transmission; Animals and people: civets/bats ~ people (possible). SARS-CoV has the general characteristics of coronavirus, but it is not a mutant of other known coronaviruses, nor is it a recombinant of known coronaviruses. SARS-CoV infects lung epithelial cells, and its S protein binds to angiotensin converting enzyme 2(hACE2) receptor, which invades and replicates in vivo. Because hACE2 is mainly in the lower respiratory tract, the symptoms of the upper respiratory tract are lacking, and the virus often peaks when hospitalized, which is easy to cause nosocomial infection of the lower respiratory tract.

2. MERS coronavirus (MERS-CoV)

Middle East Respiratory Syndrome (MERS) was caused by MERS-CoV, which was first confirmed in Saudi Arabia in 2012, affecting 27 countries and regions around the world, with a mortality rate of about 35%. According to statistics of a case, the mortality rate increases with age. The mortality rate is 39% in people younger than 50 years old and 75% in people over 60 years old. The longest incubation period is 14 days, and the population is generally susceptible. The median age of onset is 49 years old. Source host: it may be camel or bat. Transmission route: animal and human: dromedary ~ human (possible); People: Close contact. The infection site is epithelial cells in the lung, which causes explosive nosocomial transmission, and has obvious gastrointestinal symptoms and renal failure. It mainly binds to dipeptidyl peptidase 4(DPP4) in the lower respiratory tract, gastrointestinal tract and kidney, and there is no mutation that enhances human infection.

3. 2019 novel coronavirus (2019-nCOV)

Novel coronavirus was caused by 2019-nCOV. From mid-December 2019 to the beginning of 2020, 59 cases of unexplained pneumonia were reported in Wuhan, and similar cases were found in other regions and countries. On January 7, 2020, it was initially identified as "novel coronavirus", and on January 12, the WHO named the virus 2019-nCoV. Up to now, more than 70,000 cases have been diagnosed, and more than 2,400 cases have died, with a mortality rate of about 3.1%. It has spread to most provinces and cities in China and nearly 30 countries. The transmission routes may be droplet transmission, contact transmission and aerosol transmission. The incubation period is 1~14 days. At present, the source host may be a bat. Shi Zhengli’s team from Wuhan Institute of Virology has found that its genome is 79.5% identical to SARS-CoV and 40% similar to MERS-CoV. 2019-nCOV, like SARS-CoV, invaded by combining with human angiotensin converting enzyme 2(hACE2), infecting respiratory system, gastrointestinal tract and testis, affecting heart function and liver function. According to the current data, compared with SARS and MERS, it is more contagious and the mortality rate is not as high as the first two.

Third, actively protect against novel coronavirus

Personal protection requires frequent hand washing and hand hygiene. Cover your mouth and nose with paper towels when coughing or sneezing, which can effectively prevent the spread of droplets. Wear masks in public places, avoid contact with animals with unknown health conditions, and reduce the trading of live birds and wild animals.

At present, various industries have started to return to work. For the office, everyone should actively declare their health. If there are suspicious symptoms such as fever, fatigue and cough, it is recommended to seek medical advice in time, avoid going to work sick, strengthen ventilation and ventilation in public areas, clean and disinfect public areas and public goods regularly, keep the environment clean and hygienic, keep a proper distance when there are many people in the unified office area, and reduce centralized meetings by video and teleconference.
