● Tianhe Huishi fire accident was caused by smoke generated by electric welding sparks igniting low-temperature heat transfer medium during the pipeline reconstruction in the basement of freeze-drying workshop. The accident caused 8 of the 10 workers on site to suffocate and die on the spot, the other 2 workers died in the rescue process, and 12 rescuers were choked.

　　● The Emergency Response Law, the Regulations on the Openness of Government Information, and the emergency plans of various industries and regions all stipulate that emergency and disposal information should be disclosed to the public in a timely manner, including the cause of the accident, the number of casualties, the results of investigation stages, etc.

　　● Tianhe Huishi Company has problems in site selection, and should not be built in residential areas and areas with schools, because harmful pollutants generated by enterprises in the production process will affect nearby people. In addition, how the EIA report of this enterprise is evaluated and approved is also a problem.

　　At about 15: 40 on April 15th, a fire broke out in Qilu Tianhe Huishi Pharmaceutical Co., Ltd. (hereinafter referred to as Tianhe Huishi Company) located in Licheng District, Jinan City, Shandong Province, killing 10 people and injuring 12 others.

　　On the morning after the accident, the main leaders of Shandong Provincial Party Committee came to Jinan Central Hospital to visit the injured people in the accident, emphasizing the need to do their best to treat the wounded and comfort their families, and at the same time asking relevant departments to "release relevant information in time".

　　An insider told the Legal Daily reporter that the Opinions on Strengthening the Information Disclosure of Production Safety Accidents issued by the the State Council Safety Committee requires all regions and relevant departments to timely and accurately release information on production safety accidents, especially those with great social impact and high concern, so as to eliminate the space for false rumors and suspicions to spread. "According to the State Council’s Regulations on Reporting, Investigation and Handling of Production Safety Accidents, 10 people died in Tianhe Huishi Company’s accidents, which has reached the level of major accidents. Six days later, Tianhe Huishi Company had already resumed work, but the official did not hold a press conference and official website did not release any accident information. The leader of the accident investigation team and the list of members were not announced to the public as required. "

　　Yitan hospital

　　The wounded are in intensive care unit.

　　Tianhe Huishi Company, established in December 2006, is a manufacturer of chemical raw materials, and its major shareholder is Shandong Qilu Pharmaceutical Group Co., Ltd. (hereinafter referred to as Qilu Pharmaceutical), accounting for 60% of the shares. The other shareholder is Antique Hong Kong International Limited, accounting for 40% of the shares.

　　The day after the incident, the reporter came to Tianhe Huishi Company and smelled a peculiar smell in the air. I saw that the traffic at the company gate was normal. Except for a police car parked inside, the reporter couldn’t see the trace of an accident where 10 people died just now.

　　"Tianhe Huishi Company was formerly known as Qilu Pharmaceutical East Factory, and the locals used to call Qilu Pharmaceutical Factory. At the time of the incident, I saw many ambulances and fire engines enter the factory, but I don’t know what happened inside. Later, after watching TV, I realized that Qilu Pharmaceutical Factory had another big event. " A grandfather in Wenxingyuan Community next door said.

　　The reporter learned that after the accident of Tianhe Huishi Company, the wounded were sent to Jinan Central Hospital, Jigang Hospital and Jinan Third People’s Hospital for treatment.

　　In Jinan Central Hospital, a doctor told the reporter: "The wounded sent by Qilu Pharmaceutical Factory should live in the intensive care unit (ICU)". On the fourth floor of the general ward building, the reporter saw that the door of the intensive care unit was closed and could not enter.

　　Subsequently, the reporter came to Jigang Hospital and found that two wounded people lived in a ward of neurology in the rehabilitation building. When I arrived in the ward, the nurse told the two wounded people that they had left. "I don’t know whether to leave the hospital or transfer to another hospital."

　　In the Third People’s Hospital of Jinan, a medical staff told the reporter that if you want to find the wounded sent by Qilu Pharmaceutical Factory, you can go to the intensive care unit to ask. In the elevator to the intensive care unit, someone confirmed to reporters that there were indeed several injured people in the intensive care unit.

　　In front of the intensive care unit, there are two people, a man and a woman. The reporter asked them if they were the families of the wounded in Qilu Pharmaceutical Factory, and they all shook their heads and said no. Later, the woman pointed to a man with glasses not far away and said, "Isn’t that man from Qilu Pharmaceutical Factory?"

　　At this time, the reporter found that the man with glasses has been following him to the intensive care unit since the reporter entered the hospital hall. The reporter went over and asked if the man wearing glasses was a staff member of Qilu Pharmaceutical Factory. The man repeatedly denied that "my family has a cerebral infarction and lives in the ICU ward".

　　In front of the intensive care unit, the reporter contacted through the doorbell and wanted to go in to find out if there were any wounded people in Qilu Pharmaceutical Factory. The medical staff inside said, "It’s not visiting time, and no one can come in."

　　On the afternoon of April 16th, the reporter came to the guard room of Tianhe Huishi Company. After checking the press card, a security guard said, "We have a special person to receive reporters."

　　In less than two minutes, two men came and drove the reporter to the management Committee of Lingang Economic Development Zone nearby. The reporter met Wang, deputy director of the cadre department of the Propaganda Department of Jinan Municipal Committee.

　　Deputy Director Wang told reporters that Jinan has set up a special class for Tianhe Huishi Company’s accident, and the final investigation result has not yet come out. At present, first, there is no fire at the scene and the surrounding environment has no impact; Second, 12 wounded were slightly injured and were treated in the hospital; Third, the production order of Tianhe Huishi Company has returned to normal.

　　Deputy Director Wang also said that the wounded in the intensive care unit are not necessarily seriously injured. "It may be because they are scared and need some time to recover."

　　The reporter asked if the special class had any plans to hold a press conference or report the accident on the government website. Deputy Director Wang replied, "Not yet".

　　Ertan Emergency Management Bureau

　　Repeated explosion accidents without administrative punishment.

　　The reporter learned that since 2015, Tianhe Huishi Company has experienced many explosions of different sizes. The most influential one happened on October 10, 2016.　

　　According to media reports, at about 20: 50 on the same day, a pressure vessel containing alcohol exploded in the wastewater system of Tianhe Huishi Company, causing the nearby cable bridge to break and some roofs to collapse, and white powder was floating around the incident, with a pungent smell. "No casualties were caused and the direct economic loss was about 200,000 yuan."

　　The explosion ignited a decade-long feud between Tianhe Huishi Company and neighboring Licheng No.2 Middle School. Previously, Licheng No.2 Middle School had hundreds of complaints every year because of the odor of pharmaceutical factories. Parents of teachers and students have been protesting through letters and visits.

　　The former Licheng District Safety Supervision Bureau issued a "Enforcement Decision" to Tianhe Huishi Company: "In the case that safety cannot be guaranteed before the hidden dangers of major accidents are eliminated, it is ordered to evacuate the workers from the dangerous area and order your unit to temporarily stop production."

　　Then, the Jinan Municipal People’s Government approved the establishment of the "10.10" explosion accident investigation team of Tianhe Huishi Company, which is composed of the Municipal Safety Supervision Bureau, the Supervision Bureau, the Public Security Bureau and the Licheng District Government. Finally, the suggestions on the responsibility identification and handling of relevant units and personnel are: it is suggested that the Licheng District Safety Supervision Bureau should "strictly impose administrative penalties on the illegal and illegal acts of the accident enterprises" in accordance with the relevant provisions of the Safety Production Law, the Regulations on the Safety Management of Hazardous Chemicals and other laws and regulations.

　　However, the reporter looked up the data of Tianyan and found that Tianhe Huishi Company, which had many explosion accidents, had no information on administrative punishment.

　　On the afternoon of April 16th, the reporter came to Licheng District Emergency Management Bureau to interview Tianhe Huishi Company about administrative punishment. In the office on the second floor of Licheng District Emergency Management Bureau, a wang xing staff member telephoned the relevant personnel and said, "I am not a law enforcement officer, and I don’t know the punishment for Tianhe Huishi Company. But there was no punishment last year. " Finally, the staff member said that it is necessary to find law enforcement agencies to understand the relevant situation before replying.

　　On the morning of April 17th, the reporter went to Licheng District Emergency Management Bureau again and found that the staff of wang xing was not in the office. A female staff member who claimed to be in charge of finance said: "Today, everyone in the unit went out to do things."

　　The reporter saw that a staff member of the Supervision Section I was in the office and was about to ask. Unexpectedly, the female staff member followed closely and quickly pushed the staff member away.

　　According to related reports, the Tianhe Huishi accident was caused by smoke generated by electric welding sparks igniting low-temperature heat transfer medium in the process of pipeline reconstruction in the basement of freeze-drying workshop. The accident caused 8 of the 10 workers on site to suffocate and die on the spot, the other 2 workers died in the rescue process, and 12 rescuers were choked.

　　An insider told the reporter that the on-site construction personnel were not employees of Tianhe Huishi Company, but were working for a third party, and the accident was caused during the welding process.

　　In order to find out about the pipeline reconstruction project of freeze-dried basement of Tianhe Huishi Company, the reporter came to Licheng District Housing and Urban-Rural Development Bureau. The staff told the reporter that the Housing and Construction Bureau is mainly responsible for the construction of above-ground objects, pipeline reconstruction projects and the like, and should go to the safety supervision department to ask.

　　So, the reporter came to the Licheng District Emergency Management Bureau for the third time and met the female staff member he had seen before. The staff member said, "I am in charge of finance, and nothing is clear."

　　The reporter asked for the bureau leader, and she replied: "All the bureau leaders have gone out, and no one else knows."

　　The reporter saw someone in the innermost command center and was about to walk over and was stopped by him. "There is a meeting to study, so don’t disturb their normal work."

　　Santan funeral parlour

　　Most of the families of the deceased have signed compensation agreements.

　　The reporter learned that just two months before the accident of Tianhe Huishi Company, Licheng District Committee and District Government held a summary and commendation meeting for the economic and social development of the whole region and a work deployment meeting. At the meeting, Tianhe Huishi Company won the subsidy for high-end talents in key industries supported by Licheng District’s 2018 "Advanced Enterprise for Fiscal and Tax Contribution of Real Economy" and Licheng District’s 2018 "Golden Ten Articles" talent policy, and the enterprise’s talent introduction and education award.

　　Local residents told reporters that Licheng No.2 Middle School, which is adjacent to Tianhe Huishi, had complained to the relevant departments many times because of the factory odor and other reasons. Later, under the research of public security bureau, safety supervision bureau, environmental protection bureau, education bureau and letters and calls bureau, it was decided to relocate the school site. "The government does not move enterprises to move schools, which should be related to Tianhe Huishi being a big taxpayer. After the accident, the company only stopped production for one day and resumed production. "

　　An insider told reporters that the controversy caused by the odor of Tianhe Huishi Company has not been reduced with the relocation of Licheng No.2 Middle School. Residents of Wenxingyuan Community, which is separated from Qilu Pharmaceutical by a wall, sometimes smell the peculiar smell floating from the pharmaceutical factory. The employee family building of the former Jinan No.2 Textile Machinery Factory, which is less than 100 meters away from the fifth workshop of Tianhe Huishi Company, has also been plagued by odor. "There are Dongjia Central Kindergarten and Dongjia Central Primary School, which are only a few hundred meters away from Tianhe Huishi Company." The insider said.

　　Because of dissatisfaction with the pollution of Tianhe Huishi Company, the neighbors strongly urged the company to move out of Dongjia Street. In fact, Qilu Pharmaceutical also has the idea of relocating Tianhe Huishi Company. In 2017, Tianhe Huishi Company invested a total of 7.48 billion yuan to build Qilu Tianhe Huishi Leling Pharmaceutical Industrial Park in Tieying Town, Leling City, Dezhou City.

　　An insider told reporters that after learning that Qilu Pharmaceutical had the idea of relocation, the local government tried its best to retain it. Shortly before the accident of Tianhe Huishi Company, a major leader in Jinan severely criticized the Licheng District Government and relevant departments for wanting to move.

　　An official in Jinan, who asked not to be named, told reporters that after the accident, although the public security has intervened, it has not yet been formally filed. "At present, it is still being investigated by the safety supervision department."

　　The reporter learned that there are two funeral homes in Jinan, one is Jinan funeral home and the other is Lianhuashan funeral home. After some analysis, the reporter took a taxi to Lianhuashan funeral home, which is close to Tianhe Huishi Company.

　　In the service hall of the funeral home, there are dozens of people in the cremation. On a computer, the staff is printing a white note attached to the elegiac couplet for the deceased "Wang Xtian". The reporter walked over and looked at it. It read "Equipment Department of Qilu Pharmaceutical Group Co., Ltd. and Qilu Tianhe Huishi Pharmaceutical Co., Ltd.". On the registration form of cremators in the funeral home, the cause of death of "Wang Xtian" was "accident".

　　A middle-aged woman in a black coat told reporters that she accompanied a friend from the village to the funeral home. Their village is about 7 kilometers away from Tianhe Huishi Company, and their friend’s husband, a worker from Qilu Pharmaceutical Factory, died in the accident.

　　Next to a security guard post at the intersection of the funeral home, a short-haired lady was sitting on the ground crying, and several people beside her were comforting and wiping their tears. In their intermittent crying, the reporter learned that Ms. Short Hair’s younger brother also died in the accident of Tianhe Huishi Company.

　　In the funeral home, the reporter learned from the chat of several family members that most of the family members of the deceased have signed compensation agreements with the company. One of them said: "Among the dead, there are only three people in the pharmaceutical factory, most of whom are from the third-party construction unit, and there are eight people."

　　On the third day of Tianhe Huishi Company’s accident, the reporter came to Lianhuashan funeral home again, hoping to know about the aftermath. A staff member surnamed Zhou in the funeral home office called the curator and replied that "I will be back soon after working outside, so let the reporter wait."

　　More than two hours later, the reporter did not wait for the director of the funeral home, but waited for Deputy Director Wang and two other government workers.

　　On the way back to the city, the reporter mentioned that some family members in the funeral parlour claimed that the death toll had exceeded 10. In this regard, Deputy Director Wang denied it. "At present, the death toll is absolutely 10, and the government dare not and there is no need to hide it."

　　When the reporter asked the name of the third-party company that contracted Tianhe Huishi Company’s freeze-dried basement pipeline reconstruction project, Deputy Director Wang said it was unclear, "Ask the leader before replying".　

　　As of press time, I still have not received any reply.

　　(Reporter Shao Mingliang, all-media reporter of Sichuan Daily, Li Miao) On July 12th, the second joint meeting of provincial river and lake chiefs in the Yellow River Basin was held. The meeting was held by video, with the main venue in Chengdu and sub-venues in the Yellow River Conservancy Commission and other eight provinces (regions) in the Yellow River Basin. Huang Qiang, the rotating convener of the joint meeting, deputy secretary of the Sichuan Provincial Party Committee and governor, presided over the meeting and delivered a speech at the main venue in Chengdu.

　　At the meeting, Cai Rangtai, member of the Standing Committee of Qinghai Provincial Party Committee and Vice Governor, Hu Yun, Vice Governor of Sichuan Province, Xu Yanwen, Deputy Secretary General of Gansu Provincial Government, Mai Yanzhou, member of the Standing Committee of Ningxia Hui Autonomous Region Party Committee and Vice President of the District Government, Chibatu, Vice Governor of Shanxi Province, Yang Qinrong, Vice Governor of Shaanxi Province, Xu Mingfei, Vice Governor of Henan Province, and Chen Ping, Vice Governor of Shandong Province made exchange speeches; Zhou Haiyan, director of the office of the joint meeting and deputy director of the Yellow River Conservancy Commission, made a report on the work of the joint meeting. The meeting reviewed and approved the Guiding Opinions on Implementing the Yellow River Protection Law in the Yellow River Basin and the Guiding Opinions on the Construction of Village-level Rivers and Lakes Management and Protection System in the Yellow River Basin.

　　In his speech, Huang Qiang said that in recent years, Sichuan has firmly established its upstream awareness, shouldered upstream responsibilities, unswervingly followed the road of ecological priority and green development, strived to build a business card of the world’s most beautiful plateau wetland national park, and constantly consolidated the ecological background of "beautiful Sichuan". The achievement of these stages lies in the scientific guidance of the supreme leader’s ecological civilization thought, thanks to the care and guidance of the Ministry of Water Resources, the Yellow River Water Resources Commission, the National Development and Reform Commission, the Ministry of Ecology and Environment, the Ministry of Natural Resources, the Ministry of Finance and other ministries, and inseparable from the support and help of the provinces (regions) along the Yellow River.

　　Huang Qiang said that in 1952, Chairman Mao issued a great call to "do a good job in the Yellow River". Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has personally planned, personally deployed and personally promoted the national major development strategy of ecological protection and high-quality development in the Yellow River Basin, emphasizing "making the Yellow River a river of happiness for the benefit of the people". The Law on the Protection of the Yellow River, which came into effect on April 1 this year, has opened a new chapter in the history of the Chinese nation’s management of the Yellow River. As a province along the Yellow River, we should take the political responsibility of "consistency", thoroughly implement the Yellow River Protection Law, and resolutely safeguard the An Lan of the Yellow River; With the effective action of "grasping to the end", we will build a compact minimum work unit and strive to improve the appearance of grass-roots rivers and lakes; With the struggle spirit of "promoting as one", iron core arrangement, iron surface inspection and iron fist law enforcement will vigorously promote the ecological protection and high-quality development of the Yellow River Basin; With the "as always" linkage and cooperation, give full play to the role of the joint meeting mechanism, promote the great protection and governance in all directions in the whole basin, and jointly sing the "Yellow River Chorus" in the new era.

　　Chen Dayong, director of the Department of Rivers and Lakes Management of the Ministry of Water Resources and director of the River Chief Office, attended the meeting and delivered a speech at the main venue. He pointed out that in recent years, under the strong leadership of the State Council of the CPC Central Committee, the provinces (regions) in the Yellow River Basin have promoted the long-term system of rivers and lakes to take root, and the management and protection of rivers and lakes in the Yellow River Basin have opened up a new situation, and the appearance of rivers and lakes has continued to improve. He emphasized that this year is the first year to fully implement the Yellow River Protection Law. Guided by the Supreme Leader’s Socialism with Chinese characteristics Thought in the New Era, we should accurately grasp the new situation and new tasks, strengthen the implementation of long-term responsibility of rivers and lakes, assessment, incentive, supervision and inspection, legal management of institutional mechanisms and scientific and technological support, spatial control of water shoreline and construction of Happy Rivers and Lakes, and constantly improve the modernization level of management and protection, making new and greater contributions to the sustainable utilization of rivers and lakes and the sustainable development of the Chinese nation.

　　Relevant units of the Yellow River Conservancy Commission, responsible comrades of the nine provinces (regions) along the Yellow River, etc.

Looking at the news, recently, a data map about the infection efficiency of Kexing was circulated on the Internet, which indicated that, according to the latest data of the fifth round of epidemic in Hong Kong, the effective rate of Kexing in preventing Omicron was low. Even after the third injection, the effective rate of preventing infection was only 36% on the 14th day after inoculation, but only 8% after six months.

So, is this really the case?

This is not true statistics.

Tracing back to the source, we found that this picture was first seen in a simulation model of the epidemic development of Hong Kong universities reported by the Hong Kong investigative news agency Fax Agency in February this year. The data content is the calculated result of the model, not the real statistical data of Hong Kong society.

On February 10th, the School of Public Health of HKU released the simulation model of epidemic development in The 5th Wave [1], in which the efficiency of each vaccine combination in different periods was calculated based on the data of different medical studies. The study estimated that the effective rate of preventing Omicron variant virus infection was 36% on 14th day after the third dose of Kexing vaccine, and it dropped to 8% after 6 months.

So, what is the real situation?

According to the epidemic data released in Hong Kong on December 23rd, in the fifth round of epidemic (from December 31st, 2021 to December 21st, 2022), 2.32 million people were infected in Hong Kong, more than 7.04 million people have been vaccinated with at least one dose of vaccine, and 627,000 people have been vaccinated with the fourth dose of vaccine.

According to a rough calculation,There is no significant difference in infection ratio between inactivated vaccine and mRNA vaccine.

Taking the infection ratio after the fourth injection as an example, the average infection ratio of inactivated vaccine was 11.97%, while the infection ratio of mRNA vaccine was 8.99%, with a difference of 2.97%. This difference decreases with age. In the group over 80 years old, the proportion of infection between them is only 0.93%.

Moreover, with the increase of the number of vaccination agents, the effectiveness of preventing infection has increased.

The inactivation effect of anti-infection is slightly lower than that of mRNA vaccine.

Although there is no big difference in the actual infection rate, from the perspective of preventing infection,The effectiveness of inactivated vaccine against infection is indeed lower than that of mRNA vaccine.

According to the paper published by the Institute of Public Health of the University of Hong Kong in November this year [2], this study analyzed the effectiveness of Fubitai and Kexing COVID-19 vaccine through the serum survey of 5310 subjects in Hong Kong.

It was found that the effectiveness of inactivated vaccine (31%) was slightly lower than that of mRNA vaccine (47%) 7 days after inoculation.

Both of them are effective in preventing COVID-19 in the short term.

But by contrast,Inactivated vaccine has a short validity period.

The effective concentration of mRNA vaccine antibody remained in blood for a long time, and the effectiveness declined by half after 104 days. The semi-decline period of inactivated vaccine is about 40 days.

The strength of effectiveness may be related to the technology adopted by the vaccine.

The mRNA vaccine contains the messenger ribonucleic acid (mRNA) of the virus, and its working principle is to send instructions to the host cell to replicate the spike protein, so that the immune mechanism can produce antibodies in time to deal with the virus. The inactivated vaccine is injected with a complete, killed copy of the virus, making it impossible to replicate without causing disease.

The two technologies are different, so the effectiveness is different.

Inactivated vaccines are equally effective in preventing severe illness and death.

Although it is not effective in preventing infection, the effect of inactivated vaccine is equal to or even better than that of mRNA vaccine in preventing severe illness and death.

According to the paper published by the Medical College of the National University of Singapore in November this year [3], although the antibody response guided by inactivated vaccine is not as good as that of mRNA vaccine, inactivated vaccine can trigger a wide range of immune responses against different protein viruses.It is more effective against severe infection..

It is found that inactivated vaccines are more likely to produce T cell reactions against viral proteins than other types of vaccines. Inactivated vaccines stimulate cells called CD4 T, and when they recognize virus antigens, they release chemicals that become cytokines to help activate other types of immune cells.

Professor Antonio Bertoletti, who is in charge of the project, said that T cells are more effective in improving diseases than antibodies because of Omicron’s strong immune escape ability.

According to the actual data, in this round of epidemic in Hongkong, the total case fatality rate (or overall case fatality rate) is 0.71%, and the probability of the unvaccinated people dying of Covid-19 infection is 2.87%. The mortality of one dose of Kexing vaccine was 1.25%, two doses was 0.31%, and three doses was 0.04%.

In other words,The mortality rate of people without vaccination is 71.8 times higher than that of people with three doses of Kexing vaccine.

According to the paper published by the Institute of Public Health of the University of Hong Kong in July this year [4], after three injections, the effective rate of inactivated vaccine for preventing severe illness and death exceeded 95%.

On the average, inactivated vaccine is no different from mRNA vaccine. The effective rate of inactivated vaccine is 97.23%, which is only 1.18% lower than that of mRNA vaccine. In the prevention of COVID-19’s death, the effective rate of both reached 98%, and the difference was only 0.45%.

Even in some age groups, the effective rate of inactivated vaccine is better than that of mRNA vaccine. For example, for people over 80 years old, the efficiency of inactivated vaccine in preventing severe illness and death is higher than that of mRNA vaccine.

According to a paper published by the Chilean Ministry of Health in February this year [5],Inactivated vaccines are equally effective in preventing severe diseases in children and adolescents.

It was found that for children and adolescents aged 6 to 16, the effective rate of two inactivated vaccines against hospitalization was 91%, and the confidence interval was 87.8% to 93.4%. The effective rate of preventing severe illness (that is, staying in ICU) is 93.8%, and the confidence interval is 87.8% to 93.4%.

On the whole, whether it is inactivated vaccine or mRNA vaccine, booster vaccination can provide substantial protection against infection in Covid-19, including mild and asymptomatic cases.

Although Covid-19 infection in China has been adjusted to "Class B tube" at present, "keeping healthy and preventing severe diseases" is still the focus of epidemic prevention, and it is still necessary to continue to promote vaccination, especially for the elderly.

　　Just after the summer vacation, dozens of parents in a kindergarten in Jiangyin, Jiangsu Province are worried about one thing about their children. According to several parents told The Paper, a teacher in the park was diagnosed with tuberculosis during the summer vacation, and then 28 children and 4 faculty members in the park were found to be infected with tuberculosis, and 5 of them were diagnosed with tuberculosis.

　　Jiangyin City Center for Disease Control and Prevention (hereinafter referred to as CDC) confirmed the above statement to The Paper. Five children diagnosed with tuberculosis are currently out of school and taking therapeutic medication, and 23 children infected with mycobacterium tuberculosis are taking preventive medication.

　　According to Jiangyin’s official introduction, after the relevant epidemic situation was monitored in early July, the functional departments and territories did a lot of work, and experts from provincial and municipal CDC participated in the whole process of support, and repeatedly made face-to-face explanations to parents, accompanying parents to invite the most famous experts in China to consult in Shanghai, and the epidemic situation was handled as quickly, legally and effectively as possible.

　　At present, the kindergarten has screened more than 270 teachers and students in the whole kindergarten. At present, there are no new cases of tuberculosis and the disease has not spread further.

　　28 children were infected, the first mass incident of tuberculosis in kindergarten in Jiangyin.

　　The incident kindergarten is the experimental kindergarten in Zhouzhuang Town, Jiangyin City (Nijiaxiang Branch).

　　According to the director of the park named Sun, The Paper was told that in May and June this year, a teacher in the park, Li Qing (a pseudonym), suffered from throat discomfort and other symptoms. After that, the teacher went to Jiangyin People’s Hospital and Jiangyin Chinese Medicine Hospital for examination on May 26th and June 2nd respectively.

　　"The results of the examination at that time were allergic rhinitis and allergic cough, and no tuberculosis was detected." Sun Yuanchang said.

　　However, the condition is still not good. After the summer vacation this year, the teacher went to Wuxi Second People’s Hospital for examination on July 8 and learned that he had tuberculosis. "The symptoms at that time were serious and hemoptysis." Sun said.

　　Parents know that the above happened on July 15th (Sunday). On the morning of the same day, the class news informed more than 30 teachers and students in the teacher’s class to conduct T-SPOT screening for tuberculosis on July 17th (Tuesday)..

　　Chen Xianwen, director of Jiangyin CDC, told The Paper that in this round of screening, among more than 30 teachers and students in this class, 17 (including 13 students and 4 faculty members) had strong positive results, that is, they had obvious tuberculosis infection, which made them more likely to get sick.

　　On July 20, the CDC organized the 17 people to go to Jiangyin People’s Hospital for further chest X-ray examination. Chen Xianwen said that one child’s chest X-ray was abnormal, that is to say, there was a suspected tuberculosis patient.

　　But parents are not at ease with Jiangyin’s test results. Finally, under the coordination of many parties, on July 26, Jiangyin CDC, Health Planning Commission, Education Bureau and other departments organized the students to go to the Public Health Clinical Center affiliated to Fudan University in Shanghai for inspection. The final conclusion is that among the 17 people, 5 children were diagnosed with tuberculosis.

　　"As soon as we found many cases, we expanded the scope of screening in mid-August and screened more than 270 teachers and students in the kindergarten." Chen Xianwen said that in the end, 15 strong positive cases were found, and there were no new cases of tuberculosis.

　　Now,The 28 infected students are all taking medication. Among them, five students diagnosed with tuberculosis have dropped out of school at home.. Yan Haidong, deputy director of Jiangyin Health Planning Commission, told The Paper,One of the five children is the child of the sick teacher Li Qing..

　　Chen Xianwen said that after investigation, there was an epidemiological correlation between 32 infected people and the initial illness of the sick teacher, that is, the former was infected and the latter spread after the illness.

　　"This is the first tuberculosis group incident in Jiangyin that I have learned about in the past ten years." Chen Xianwen said that no new cases have been found.

　　According to Yan Haidong, the kindergartens involved organize teachers to have a physical examination every year. After passing the physical examination, they will issue a health certificate to the teachers. They checked Li Qing’s medical examination record in August 2017, and "the chest radiograph is normal".

　　Two major questions of parents

　　Although the child has been treated at present, parents still have two big questions.

　　First, they hope that the garden and the Education Bureau will explain why the teacher was not found to be suffering from tuberculosis in time and stop his class in time to prevent the disease from spreading further. Parents believe that the garden and the education department have dereliction of duty in supervision.

　　It is understood that teacher Li Qing is a nursing teacher in the kindergarten, and she usually takes care of the children’s lives most of the time.

　　"Our child coughed one day and the teacher told him to go home and rest, saying that he was afraid of affecting (infecting) other children. Why did the sick teacher cough for several months and wear a mask to attend class, and the garden still let her continue to attend class?" A student’s parents said to The Paper.

　　Xu Qianfeng, director of Jiangyin Education Bureau, told The Paper, "The key is that the teacher’s first two visits were not tuberculosis. Since it is not an infectious disease, there is no reason not to let her attend class. It is normal for a teacher to cough and have an uncomfortable voice in class. "

　　The sick teacher Li Qing (pseudonym) told The Paper that before the diagnosis, she didn’t know that she was suffering from tuberculosis. "What a great experience it is to know that I have an infectious disease and go to work. I also have children." Li Qing said that after the diagnosis in July, she told the kindergarten leaders that she was tuberculosis. Before that, kindergarten leaders sometimes asked her why "cough has been bad" and whether she had seen a doctor.

　　"Teachers and schools don’t know in advance that it is tuberculosis. How can they be held responsible? Punish teachers? Teachers are also victims. " Wang Jian, deputy director of Jiangyin Education Bureau, told The Paper.

　　Parents’ second question is why before going to Shanghai for examination, the screening result organized by Jiangyin CDC was "only one suspected tuberculosis patient", while the result in Shanghai was five cases.

　　After screening in Jiangyin, Jiangyin CDC suggested that students infected with germs can start preventive medication for patients with strong positive, which is different from therapeutic medication for patients diagnosed with tuberculosis. "If you didn’t go to Shanghai for diagnosis, didn’t the five confirmed patients delay the treatment opportunity?" Student’s parents B said to The Paper.

　　In this regard, Chen Xianwen said that the difference in diagnosis results between the two places may come from two reasons. First, "Shanghai is a CT diagnosis, and we take a chest film. There is a difference in the clarity between chest film and CT"; On the other hand, "the two diagnoses are six days apart, and the development of tuberculosis is dynamic, which may also affect the diagnosis results."

　　"We handled it according to the" Code for Prevention and Control of Tuberculosis in Schools (2017 Edition) ",and the above requirement is to take a chest X-ray. However, Shanghai’s medical technology and concept are more advanced. They use more accurate and advanced CT. We have reported the inconsistent diagnosis results caused by the two diagnostic methods to the (Jiangsu) Provincial Health Planning Commission. " Yan Haidong, deputy director of Jiangyin Health Planning Commission, told The Paper.

　　CDC: Tuberculosis is treatable.

　　Parents reported that at present, the children’s medical expenses are paid in advance by parents and later reimbursed by the government.

　　In addition to asking kindergartens to take responsibility, another issue that parents are concerned about is whether children can be cured and whether it will affect their future study and work.

　　Chen Xianwen said that after years of medical development, tuberculosis is currently preventable, controllable and treatable. For patients with strong positive, the incubation period of bacteria is generally six months. As long as they are properly treated and recuperated during this period, they can recover slowly. For patients diagnosed with tuberculosis, the general treatment period also takes half a year. "From the tuberculosis cases we have contacted before, the recovery rate is over 90%." Chen Xianwen said.He also said that cure does not mean never recurrence, and not paying attention to physical maintenance will increase the chance of tuberculosis recurrence.

　　Chen Xianwen also said that the impact of tuberculosis on studies and work is limited to the period of illness. "If you just had tuberculosis, the employer won’t refuse to hire you. If you are suffering from tuberculosis at the time of applying, it will not work. " Chen Xianwen said that people are afraid of tuberculosis because they are afraid of infection, but if it is cured, it will not have an impact.

　　What’s more, "statistics show that at present, 40% of Chinese people are infected with mycobacterium tuberculosis, but some of them are hidden and have not yet developed." Chen Xianwen said to The Paper.

　　However, parents’ concerns remain. It is reported that after the tuberculosis group incident, the enrollment rate of the kindergarten in the new semester was greatly affected. Wang Jian, deputy director of Jiangyin Education Bureau, saw from the data on September 5 that,At present, there are only more than 100 students enrolled in the park, which is nearly half of the number compared with last semester. Many parents transfer their children to other kindergartens..

　　Even, "a teacher transferred to another school and was boycotted by the parents of that school." Parents of students said to The Paper.

　　At the same time, some parents reported that Li Qing’s illness may have been infected by previous tuberculosis cases in her village and town. "It seems that (the patient) lives opposite Li Qing’s house."

　　In this regard, Li Qing told The Paper that she was unclear. "The doctor just told me that I didn’t know where I was infected before, and then my body’s resistance dropped, and I often got sick after staying up late and not resting enough."

　　Yan Haidong, deputy director of Jiangyin Health Planning Commission, said that the tuberculosis patient from Li Qing’s hometown was diagnosed with tuberculosis in January this year, but there is not enough evidence to verify whether there is a correlation between the two diseases. "It is understood that this person is not a close contact of Li Qing". "Because tuberculosis is mostly transmitted through the respiratory tract, Li Qing has a wide range of activities and many contacts, so it is temporarily impossible to verify where she was infected."

　　Cao, deputy director of Jiangyin CDC, told The Paper that at present, there is a unified online monitoring system for tuberculosis in China, and the CDC has special personnel to check the detection system every day. As long as a case of tuberculosis is found, it will begin to follow up its medical treatment.

　　The system especially focuses on monitoring key places such as schools. "If there are cases in schools, the system will automatically send relevant messages to the mobile phones of disease control personnel." Cao said.

　　Take Li Qing’s illness as an example."After she was treated in Wuxi on July 8, the doctor entered this case into the monitoring system. However, she did not indicate that she was a teacher at that time, so she was treated as an ordinary tuberculosis case." Yan Haidong said.

　　succedentOn July 12, Li Qing went to Jiangyin People’s Hospital to get medicine. "When the hospital medical staff asked about the illness, they asked about their occupation. After knowing that she was a teacher, they updated this information to the monitoring system and reported it to the competent department., our CDC staff also found in the monitoring system, and then organized school screening. "Cao said to The Paper.

　　"Now the country is very strict in the prevention and control of infectious diseases. If there are cases that are missed, the punishment is very severe." Cao said. (The Paper reporter Chen Ke intern Wan Xiaotian)

　　On March 1st, there was a heavy news from Country Garden, a leading real estate enterprise: Yang Guoqiang, the chairman and executive director of the company’s board of directors, resigned due to his age, and was replaced by his daughter and co-chairman, Yang Huiyan, with effect from March 1st, 2023.

　　In this regard, Yan Yuejin, research director of Yiju Research Institute, told the Securities Daily reporter that the resignation event was generally in line with expectations. At present, private enterprises are experiencing an intensive period of replacement of old and new, and some founders of enterprises will indeed enter the stage of resignation because of their age, so it is also a normal adjustment in itself. At the same time, the growth of Country Garden is closely related to the rapid development of urbanization in China. It is precisely because it has seized this dividend and its business scale has expanded rapidly. It is an outstanding representative of the rise of housing enterprises under the background of urbanization. At present, the replacement of old and new, how to seek new space on the basis of a new round of urbanization, this is also the content that investors pay more attention to.

　　Yang Guoqiang is 69 years old. As one of the earliest real estate entrepreneurs in China, he founded Country Garden in the early 1990s, and its famous super-market model well stepped on the rhythm of China’s new urbanization construction and achieved rapid success. In 2017, Country Garden became the first real estate enterprise to break through the threshold of 500 billion yuan and remained at the top of the country at the end of the year. Also in the same year, Country Garden ranked among the Fortune 500 for the first time, ranking 467th. By 2022, its ranking has climbed to 138th.

　　In 2022, when the real estate industry in China suffered from extreme cold, its scale shrank, the loan stopped and spread, and the news of thunder storm broke out from time to time. Country Garden’s business and sales maintained a rare stability, and there was no delay in paying the principal and interest due to breach of contract, and it became a model private real estate enterprise with benchmark significance, showing sufficient resilience.

　　At present, the real estate industry in China has just passed through the cold winter and is gradually showing a good trend. Under such a special background, Yang Huiyan took over Country Garden, which has also become an observation model for China’s modern private economy to do a good job in enterprise inheritance. After taking over the real estate aircraft carrier, can Yang Huiyan successfully carry on the business mission? Under the leadership of a new generation of successors, where will Country Garden go?

　　Expected succession

　　China’s reform and opening up has been promoted for more than 40 years. Over the past 40 years, the earliest batch of private entrepreneurs in China have created unprecedented wealth through hard exploration in the wave of reform dividend and urbanization. Forty years later, most of these entrepreneurs are over 60 years old, and they are beginning to face a new challenge-corporate inheritance.

　　Yang Huiyan was born in 1981, the second daughter of Yang Guoqiang. As early as the eve of Country Garden’s listing in 2007, when Yang Guoqiang transferred all the shares of the company worth tens of billions of yuan to Yang Huiyan, she had stepped into the public eye and attracted much attention.

　　"The inheritance of an enterprise is still a realistic development trend in the China real estate market in the next decade, whether from the traditional concept of" inheriting the father’s business "in China or from the transformation and upgrading process of the enterprise itself. Because blood is the best contract. " Gao Xianlin, vice president and senior partner of Hanjia Real Estate Consulting Co., Ltd., has quite representative views. In fact, among private entrepreneurs in the United States, Europe, Japan and Southeast Asia, there have been many classic examples of the inheritance of family businesses, and it is not uncommon to see the legend of family fortune that lasted for more than one or two hundred years. Of course, this traditional way of inheritance also has potential risks, such as whether the quality of the successor can meet the requirements and take charge of the enterprise well after inheritance.

　　Yang Guoqiang’s train of thought about children is very similar to Li Ka-shing’s. Like Li Zeju and Li Zekai, Yang Huiyan and his sister had the opportunity to sit in on the work assigned by their father at the board meeting at an early age.

　　Since joining Country Garden in 2005, she has worked in important business departments such as investment planning center, purchasing department, human resource management center and digital management center and held major management positions. In 2012, she became the vice chairman of the board of directors of the group, and in 2018, she was transferred to be the co-chairman of the board of directors. It has been 18 years since it successfully led the listing of Country Garden education sector and the spin-off listing of property sector. In fact, the industry had long expected Yang Huiyan to take over Country Garden.

　　According to insiders of the company, during his term as co-chairman, he has jointly managed the daily work of the Group with Yang Guoqiang, and was responsible for the strategic investment and new business development of the Group, and his working ability has been highly recognized by the board of directors. Yang Guoqiang’s efforts to cultivate Yang Huiyan can be described as foresight and careful layout, and it has also laid a thick enough safety mat for the long-term stable operation of enterprises.

　　The successor’s new topic

　　The market also gave positive feedback to Country Garden’s takeover. On March 1, Country Garden’s share price closed up 8.33%.

　　The inheritance of successors is not a stick-in-the-stick in the traditional sense. At present, the real estate market in China is in transition to a new development mode. How to adapt to the changing times and maintain the development competitiveness under the new situation is not only a new challenge and a new topic, but also provides a new stage for successors to show their talents.

　　Still taking Country Garden as an example, in recent years, Country Garden has strategically laid out new businesses such as construction robots and modern agriculture, which have achieved initial results, and construction robots have made a series of major breakthroughs. As of January, 2023, Guangdong Bozhilin Robot Company, a subsidiary of Country Garden, has put 33 construction robots into commercial application, with a cumulative application construction area of over 10 million square meters. In addition, Country Garden has also set up a Science and Technology Building Group, focusing on the promotion and application of the smart construction system of science and technology, which integrates advanced technologies such as construction robots, BIM digitalization and new prefabricated buildings.

　　Some insiders pointed out that smart construction is expected to bring a new look to the traditional construction industry, and it is also a great weapon for the real estate industry to cope with the new cycle, which will surely win more development space for the enterprises themselves and even the whole industry. In the exploration of new technologies and new business models, a new generation of entrepreneurs may have natural advantages. From this perspective, it may be just the right time for Yang Huiyan to take over Country Garden at such a special moment.

　　[car home Technology] On December 21st, FAW Toyota/GAC Toyota announced that there were quality problems in the hydraulic torque converter in CVT gearbox of (|)/C-HR model, and the oil circulation blade of the hydraulic torque converter was riveted badly. When the vehicle was subjected to repeated rapid acceleration and other operations, the blade might fall off, causing damage to the torque converter. In extreme cases, it might lead to power interruption while the vehicle was driving, posing a safety hazard. FAW Toyota/GAC Toyota will replace the qualified hydraulic torque converter and continuously variable transmission assembly for vehicles within the scope of recall free of charge to eliminate potential safety hazards.

"Screenshot of the recall announcement of the State Administration of Market Supervision"

"GAC Toyota C-HR/ FAW Toyota Yize IZOA』"

　　FAW Toyota will recall 10,442 IZOA models produced from September 14, 2018 to November 27, 2018; GAC Toyota will recall 9,454 C-HR models produced between September 13, 2018 and November 14, 2018. Since the CVT gearbox is standard in all the Izawa IZOA/C-HR models, all the Izawa IZOA/C-HR models produced within the above time are within the recall scope.

● Go straight to the place where the problem occurs.

　　According to the recall announcement, the problem is the hydraulic torque converter of CVT gearbox. Hydraulic torque converter exists in both AT and CVT gearboxes, and its function is to realize the soft connection between the engine output shaft and the gearbox input shaft, allowing the speed difference between the two shafts, realizing the semi-linkage state similar to that in manual gearboxes, and facilitating the gearbox to automatically shift gears.

More exciting videos are all on the car home video platform.
"Video of technical explanation of hydraulic torque converter"

　　The transmission of hydraulic torque converter depends on the internal blades. If the blades on the pump wheel, guide wheel or turbine fall off, the power from the engine will not be transmitted to the gearbox, which will cause the vehicle to lose power.

● TNGA-based Direct Shift CVT gearbox is so delicate?

　　The CVT gearbox mounted on Izawa IZOA/C-HR is the Direct Shift CVT gearbox under the Toyota TNGA architecture. There are some big differences between this gearbox and the general CVT gearbox in structure.

　　The gear ratio range of CVT gearbox mounted on Yize IZOA/C-HR reaches 7.5, which is higher than 7.0 of other CVT gearboxes with similar torque capacity. A higher transmission ratio range is beneficial to better balance the vehicle’s low-speed speed-up performance and fuel economy during high-speed cruising.

　　From a technical point of view, the design of this Direct Shift CVT gearbox to broaden the transmission range of the gearbox by increasing the starting gear transmission is quite innovative. According to Toyota’s development system, CVT gearboxes will be mass-produced. In the development stage and mass production stage, all kinds of rigorous durability tests are essential. The problem of this recall is more likely that the quality of parts suppliers is not up to requirements. At present, the CVT gearbox used by Yize IZOA/C-HR is imported from Japan, and we have not been able to obtain the information of the CVT gearbox hydraulic torque converter parts supplier. We will publish more information on the website as soon as possible.

● What will happen to the car when it breaks down?

　　The recall information simply describes the problem, but does not specify the phenomenon when the fault occurs. I checked the posts of netizens on car home Yize IZOA Forum. On December 16th, a netizen reported that the engine stopped immediately after Yize IZOA was parked in D gear, and the vehicle could not start, and the vehicle could not reverse when it was parked in R gear. Later, the netizen’s car was tested in a 4S shop, and the gearbox needed to be replaced, but it took one month for the gearbox to adjust the goods (click to view the forum post).

　　When the CVT gearbox of Yize IZOA breaks down, the torque converter loses its power transmission ability, and the vehicle will lose power. If the vehicle breaks down at the start, the vehicle can’t start, which generally has little impact on the safety of users. The trailer can be handled at the 4S shop. It is much more complicated if the internal blades of the hydraulic torque converter break in the CVT gearbox during the start-up of Yize IZOA. However, because the gearbox is equipped with input shaft speed sensor and output shaft speed sensor, and the engine is equipped with crankshaft speed sensor, when the transmission of hydraulic torque converter fails, ECU can recognize it by the above speed signal, and at this time, some protective measures will be taken. I guess the system will put the gearbox into neutral and the vehicle will lose power to slide. At this time, the user can stop the vehicle by hitting the direction and braking the pedal, and then can call the trailer to be towed back to the 4S shop for treatment.

● I am the owner of Izawa IZOA/C-HR. What should I do?

　　Since the manufacturer only started to recall from February 22, 2019, this means that there are still 2 months. What should I do as the owner of Izawa IZOA/C-HR?

　　If the gearbox of your vehicle has been damaged and the vehicle loses power, then you can only ask the trailer to tow the car back to the 4S shop for repair. Therefore, the problem of this recall caused the vehicle to break down, and the user was not responsible for the trailer fee.According to the information we have obtained at present, it takes about 10 hours to replace the gearbox, during which the manufacturer will provide a scooter or transportation subsidy.

● The gearbox with problems is not specially supplied by China.

　　This CVT gearbox matched with Toyota 2.0L naturally aspirated engine is not the only problem in China. The CVT gearbox of the new Corolla 2.0L model listed in North America, Oceania and Taiwan, China has also been recalled. In the recall announcement, it is stated that only the models with the specified production batch need to be recalled, and the remaining models have not been included in the recall list yet. Considering that the gearbox of Yize IZOA/C-HR is imported, this type of gearbox recalled by Toyota in the world is likely to come from the same faulty production line or use the same batch of faulty hydraulic torque converter parts.

● Summary:

　　According to the posts of users in car home Yize IZOA/C-HR Forum, there is no large-scale gearbox damage in these two cars, and consumers who have bought these two models need not panic excessively. The practice of recalling without large-scale failure reflects from one aspect that FAW Toyota/GAC Toyota are more responsible and sincere towards consumers. We also hope that manufacturers can nip potential problems in the bud through recall. We will continue to pay attention to the subsequent recall of Yize IZOA/C-HR. Please continue to pay attention to the relevant reports in car home. (Photo/Text/car home Chang Qinglin)

"I’m like a femme fatale?"

"I’m not bad and I don’t worry about getting married."

　　[Guest] "Stupid Root" is too red to invite.

　　"Please rest assured the audience this time, because I have a lot of songs to sing, and another guest, A Xin, said that he would sing 16 songs himself." Rene Liu’s words amused everyone, and the guests generally didn’t want to usurp the host’s role. The reason why A Xin dared to be so arrogant on May Day was of course due to his friendship with milk tea. "How good is it? We are so good … A Xin said that it took him the longest time to write a song for me this time, so good that A Xin would come to help me without saying anything if I needed help, so that I would treat him well when he came to Nanjing, haha. " Speaking of guests, everyone mentioned Wang Baoqiang, who was very popular recently because of Soldier Assault, because Wang Baoqiang was once a guest of milk tea. "When we filmed world without thieves, we all knew that we couldn’t fake acting with’ Stupid Root’ because he was very serious about every line and liked his seriousness very much, but now he is too red to invite him."

　　[Transformation] Play "femme fatale" when you have the chance.

　　In 2008, apart from the concert, the plan that Milk Tea gave itself was actually "to be an unemployed person, not to arrange any work, and to do whatever you want". In fact, Rene Liu, who is the "best prize winner", has been "applauding and making a hit" in recent years, and many investment companies even regard her as a guarantee of ratings, because her "unemployment" makes everyone feel deeply sorry, and she doesn’t agree with it. "There are still many works without my participation in the ratings. I demand that I must be fully prepared to ensure that the things I produce are good, otherwise I am sorry for investors and audiences. " A reporter asked whether milk tea wanted to transform into a bad woman. She suddenly widened her eyes and said, "Do you think I look like a snake and scorpion woman? In fact, I really want to play. Since everyone sees that I have potential, I will play next time I have the opportunity. "

　　[Love] I’m not bad, I’m not worried about getting married.

　　Later, I love you very much, and Fulfillment … Rene Liu’s songs are full of women’s affairs, but her own "lifelong event" is a problem that all her friends, relatives and fans are worried about. At the Shanghai concert, Master Bobby Chen advised her to "find someone to marry early" through video, and she replied with a grudge-like stubbornness, "I want you to take care of it!" Today’s Rene Liu is still willing to be "crazy about love", but she is long past the age of hating marriage. "In fact, a person can live a good life. You can travel everywhere. You can say that you don’t have to tell another person when you leave. A lover is not free, but you have to worry about a lot of things." As for her own wedding date, she is not in a hurry. "Even if you don’t marry, it doesn’t matter. My conditions are not bad. If you really don’t have to worry about getting married, Compared with falling in love, milk tea seems to be more willing to enjoy the love in sleepwalking on the stage of the concert. "Sleepwalking is more free than loneliness and happier than love. I hope that everyone will sleepwalk in the music of love at the concert. " Our reporter Zhang Yanwen You Xiaoyuan photo

Many netizens left messages and wanted to see it. Today it came. Let’s take a good look at it.

Let’s take a look at the appearance of Cadillac XT6. The front shape of Cadillac XT6 looks simple, and with multi-frame grille, it looks sporty. At the same time, the headlight presents a dignified design style, and the visual effect coincides with the positioning of the whole vehicle. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car, the body size of the car is 5056 mm * 1964 mm * 1780 mm. The car uses simple lines, and the side circumference gives people a very simple and fashionable feeling. With large-sized thick-walled tires, the shape is eye-catching. In terms of the rear end, the rear end looks calm, and the taillights look very round and neat.

Coming into the Cadillac XT6 car, the interior of Cadillac XT6 presents a simple design style and rich functions. The steering wheel of the car is well designed and made of genuine leather, which gives a good grip experience. Let’s take a look at the central control, with a 10-inch touch-sensitive LCD central control screen, which makes the interior style impressive and looks simple and fashionable. Let’s take a look at the dashboard and seats again. The dashboard of this car presents a fashionable and generous design style and looks strong in science and technology. The car uses leather seats, which are wide and thick, and the overall comfort and wrapping are not bad.

In addition, the car is equipped with car networking, driving mode selection, remote control key, rear wiper, interior atmosphere light and other configurations.

This car performs well in terms of space and configuration. As for the design, everyone has everyone’s aesthetics. You must also have a look at this car, which will definitely bring you unexpected surprises.

On May 21st, the first SUV—— of Chery Fengyun series, Fengyun T9, was officially launched. The new car is subdivided into four versions, and the price is 129,900 ~ 169,900 yuan.

Now buy a new car and a big gift package. Including the replacement subsidy of up to 15,000 yuan, unlimited flow for 2 years, free installation of household charging piles, etc. By the end of the conference, the T9 order volume had exceeded 50,000 units.

It’s only halfway through 2024, and the plug-in hybrid market has become a red sea. Roewe D5DMH was launched yesterday, and the starting price of 110,000 yuan is quite attractive. Today, there will be a king bombing immediately, and the Fengyun T9 with 129,900 cars is a 4-meter-8 medium-sized SUV … In terms of power, everyone is most concerned about, the new car is equipped with a plug-in hybrid system consisting of a 1.5T engine and a single/three-gear DHT. And there are many bright spots in the safety part of the new car.

Looking at the design first, the front face of Chery Fengyun T9 is quite new energy-oriented, and the huge grille and body are treated in the same color, so it seems that the front face has a strong sense of unity. Of course, the outlines of these air inlets still outline Chery’s family style. However, it is a pity that the light strip is not integrated into the grille, so it will not shine at night. In terms of headlight configuration, the new car comes standard with LED headlights with automatic headlights.

The side shape is very simple, a medium-sized car should have a steady design, but it also uses the popular hidden door handle. In terms of body size, the length, width and height of the new car are 4820/1930/1699mm and the wheelbase is 2820mm respectively. The rear of the car is also a penetrating light group, and the whole tail is very thick.

(5 ordinary colors +1 limited color (ink rock ash))

As for the interior, Chery Fengyun T9 takes the horizontal extension as the overall design concept, and the instrument panel has rich design layers, and also integrates entertainment functions into the 15.6-inch central control panel. Of course, common functions such as driving mode switching, air conditioning and power mode are placed on the central control armrest box in the form of physical buttons.

The new car is equipped with Qualcomm Snapdragon 8155 chip and 5G network, and there are 14 Sony stereos and 256-color ambient lights in the high-profile models. It is also equipped with 50W mobile phone wireless fast charging, and there is an air outlet under the charging panel for cooling the mobile phone.

The seven-seat version can be said to be fully equipped, and the front seats have 10-point massage, ventilation and heating. The queen’s co-pilot lies flat with one button, and the maximum opening angle of the seat cushion leg rest reaches 128 degrees, and the maximum opening angle of the seat cushion backrest reaches 125 degrees.

(Chery’s mainstream cars will undergo rigorous safety tests)

Of course, the biggest highlight of the new car is safety. The high-strength steel in white body accounts for 85%, and the ultra-high-strength steel accounts for 21%. There is also an aluminum alloy anti-collision beam at the front of the car+the pedestrian below is prevented from being involved in the anti-collision beam.

(Rolling and falling test vehicle)

The whole vehicle comes standard with 7 airbags, including the head air curtain running through the front and rear rows (2060mm). Previously, the new car completed the first domestic challenge of falling after a side impact, that is, after being hit by a 4.5-ton truck, it immediately fell into a pit with a vertical height of 8 meters. The high-voltage electricity of the test vehicle was automatically disconnected, the battery pack was not displaced, smoked or caught fire, the oil circuit was not leaked, the airbag of the whole car was normally opened (and the pressure was maintained for 6 seconds), the door was normally opened, and the 24-hour rescue phone in the car was automatically dialed. In terms of safety, Chery Fengyun T9 really made great efforts.

In terms of power, Chery Fengyun T9 is equipped with Kunpeng super hybrid C-DM system, and the maximum power/torque of the engine is 115kW/220Nm. The thermal efficiency reaches 44.5%. Short battery life (120km) motor power/torque: 150kW/310Nm. The long-life version (200km) is equipped with a three-speed hybrid gearbox, and the motor power reaches 160kW. The short battery life version of the system has a comprehensive power of 265kW and a torque of 530Nm, which is equivalent to that of a V6 fuel vehicle. The new car supports 41kW fast charge, which can be charged from 30% to 80% in 20 minutes. Full battery life can reach 1800+km, and the fuel consumption per 100 kilometers under comprehensive working conditions is about 4L.

The scale of domestic hybrid market is growing. According to a data from China Automotive Research Institute, the sales volume of electric vehicles in China in Q1 this year was 1.305 million units, up 13.3% year-on-year, while the sales volume of hybrid vehicles was 784,000 units, up 81.2% year-on-year. The momentum of hybrid vehicles is stronger than that of pure electricity. You can use oil and electricity, you don’t need to change your car habits, just like an oil car. Compared with pure electricity, plug-in is really more suitable for domestic consumers, especially those who are only allowed to have one car at home.

In addition, with the further exploration of battery cost, there are more and more plug-in hybrid vehicles with long pure battery life on the market. Last year, the loading capacity of power batteries for plug-in passenger cars increased by 109.8% year-on-year. Pure battery life has also increased from the general 50km two years ago to more than 100 or even 200km this year.

Looking back at today’s protagonist, Chery Fengyun T9, the starting price of less than 130,000 can already give you a long battery life of 120km, and there are so many scientific and technological equipment. The most critical thing is the safety dimension, the body-in-white with good materials, seven airbags, etc. As a just-needed SUV, I personally think that T9 is quite attractive, but I just don’t know how to drive it.
