Many people have taken or are planning to take a shot of flu vaccine, but they may be blindsided as soon as they come to the vaccination clinic-how can there be so many kinds of flu vaccines?

● There is "inactivation" and "inactivation";

● There are "injections" and "nasal sprays";

● There are "trivalent" and "tetravalent";

● There are "cracking" and "subunits".

And each kind, there are different brands and different prices of products. In another hospital, I found that there are different choices.

I just want to get a good vaccine. Why is it so difficult and brain-wasting?

How to choose the flu vaccine?

For the flu season in 2023/2024, there are the following flu vaccines in mainland China [4]:

● Children from 6 months to 3 years old: trivalent inactivated influenza vaccine and tetravalent inactivated influenza vaccine are available;

● Children and adults over 3 years old: trivalent inactivated influenza vaccine and tetravalent inactivated influenza vaccine are available;

● Children aged 3 to 17: There is also a trivalent live attenuated influenza vaccine.

Is it a little winding? It doesn’t matter, a table shows clearly:

At present, influenza vaccines that need intramuscular injection are all "inactivated" vaccines (commonly known as "dead vaccines").

The "dead" vaccine does not contain live viruses, and vaccination will not make people get the flu. Generally, sufficient immunity is generated after 2 to 4 weeks of inoculation.

The flu vaccine that needs nasal spray is an attenuated live vaccine, which is suitable for people aged 3 to 17.

Studies have shown that nasal spray can produce nasal mucosal antibodies in as little as 3 days [5].

Therefore, for those children who are particularly afraid and resistant to "injection" or have skin diseases in their upper arms and no suitable injection site, "nasal spray" vaccine seems to be a more friendly choice.

However, those children who have immunodeficiency diseases, received other attenuated live vaccines (such as measles vaccine, chicken pox vaccine, etc.) within one month, or have severe rhinitis, nasal congestion, runny nose and other symptoms are not suitable for vaccination.

Of course, no matter inactivation or inactivation, it has a good protective effect and can be selected as needed.

The "price" in the vaccine name does not mean "price", but refers to the type of the same pathogen.

For example, "trivalent pneumonia vaccine" can prevent infections caused by 13 kinds of pneumococci; The "9-valent HPV vaccine" can prevent infections caused by 9 kinds of HPV (human papillomavirus).

The higher the "price", the more types of pathogens are covered, and the wider the infection can be prevented (many people will mistakenly write it as "intermediary" and "rank", which is wrong).

Influenza viruses that can infect humans and cause widespread epidemic are mainly H1N1 and H3N2 subtypes of influenza A and Victoria and Yamagata strains of influenza B..

The tetravalent influenza vaccine can prevent one more influenza virus (Yamagata strain B) than the trivalent influenza vaccine.

At the end of September this year, the World Health Organization (WHO) believed that since March 2020, Yamagata strain of influenza B had not been monitored and isolated worldwide [6].

This may be related to the epidemic situation in COVID-19 in recent three years and its prevention and control, especially the changes in people’s living habits and behaviors (such as wearing masks, reducing travel and increasing social distance) [7].

However, the fact that the virus has not been detected for the time being does not mean that the virus has "completely disappeared" and there is still the possibility of making a comeback in the future. As a precaution, WHO continues to provide recommendations on the composition of tetravalent influenza vaccine [6].

Therefore, for this year, playing 3 prices is enough; At 4 prices, you won’t lose. When choosing a flu vaccine, you don’t have to worry about the specific price.

Some people may have found that the same "inactivated" vaccine is also divided into "split" and "subunit". What’s the difference?

In fact, inactivated vaccine is to completely "kill" pathogens (such as influenza virus), take their "corpses" and make them into vaccines after processing.

Some inactivated vaccines use whole bodies, such as inactivated hepatitis A vaccine, rabies vaccine and COVID-19 vaccine.

The "split" vaccine is to split, disintegrate, filter and purify the dead virus, which greatly reduces the adverse reactions of the vaccine [8].

The "subunit" vaccine goes a step further, removing the internal protein of the virus and only extracting some components (such as neuraminidase and hemagglutinin of influenza virus), with less impurities [9] and better safety.

However, at present, the production of "subunit" influenza vaccine is relatively small and the price is more expensive.

The Technical Guide for Influenza Vaccine Vaccination in China issued by China Center for Disease Control and Prevention indicates that people who can vaccinate vaccine products of different types and manufacturers can voluntarily vaccinate any kind of influenza vaccine, and there is no prior recommendation [4].

In other words, any kind of flu vaccine can provide us with good protection. What is important is to vaccinate in time, not to choose or wait.

May each of us spend this coming winter safely and healthily!

March 8 is a women’s day, and it was on this day 16 years ago that Huang Lei and Sun Li got the certificate and became husband and wife. At about 1 am today, Huang Lei posted a message on her personal social platform to express her confession to Sun Li, and Sun Li immediately forwarded this Weibo, with the caption: "On this day 16 years ago, we woke up and went to get the certificate."

Although their words seem plain as water, their feelings in these 16 years are very sweet. They have long regarded each other as their closest family.

Some netizens ridiculed after reading it: "I wanted to order takeout for breakfast in the morning, but I was full when I saw this Weibo."

In fact, Huang Lei Sun Li is also very sweet and happy in her daily life. When Huang Lei goes out to film, Sun Li takes care of the children at home, while when Huang Lei is at home, he becomes a "yellow kitchen" to cook food for his family and treat his wife every day.

Although they don’t usually show their love, they can still feel their love and happiness. I believe they will always be happy.

After receiving an offer of 13 billion yuan from Gree Electric, Yinlong New Energy became the focus of market pursuit and discussion. The "Securities Daily" reporter also went to the Yinlong New Energy Automobile Factory in Wu ‘an City, Hebei Province to find out.

In Yinlong New Energy Industrial Park, the reporter saw that the brand-new factory had just been completed, and the robot’s arm was waving in the factory, and there were staff operating the machine from time to time. A person in charge of Yinlong New Energy said: "This is the world’s largest lithium titanate material and battery production base, which integrates a fully automatic, efficient and industrialized new energy automobile industry chain."

After Gree announced that it would spend 10 billion yuan to acquire Yinlong New Energy, the acquisition disclosed by Gree and the technical path and valuation of Yinlong New Energy were widely discussed in the market. In this regard, Wei Yincang, chairman of Yinlong Group, said in an interview: "The company’s orders are growing rapidly. In this year and next year, the company will usher in high sales growth, and the valuation underestimation does not exist."

Dong Mingzhu, the chairman of Gree Electric, revealed that his plan is to make Gree March towards the goal of a 200 billion yuan enterprise through acquisition.

Take the lithium titanate route alone and expand at a high speed within one year

In a brand-new factory in Yinlong, the reporter of Securities Daily noticed that the sign "It has been put into production for 20 days" was posted on the wall.

A worker told the reporter: "This factory has only been put into production for about 20 days. It is expanded on the original basis. At the same time, new technologies are introduced. The production of the factory is extended in the upstream of new energy vehicles, and the materials of batteries are produced at the same time."

On the occasion of the large-scale development of new energy vehicles, most domestic manufacturers chose the technical route of Ferrous lithium phosphate, while foreign brands such as Samsung chose lithium ternary. In the choice of different technical routes of batteries, Yinlong New Energy did not choose the conventional route in the market, but embarked on the road of independent research and development of lithium titanate.

A considerable part of the newly-built workshops of Yinlong New Energy that the reporter saw are producing lithium titanate batteries. At present, Yinlong plans to expand the production line of lithium titanate batteries on a large scale. According to the plan, it wants to build a closed cycle industrial chain strategic layout of new energy vehicle powertrain and vehicle R&D, production and sales with the unique lithium titanate technology as the core.

However, this battery technology is still under discussion in the market, and the market has different opinions on its advantages and disadvantages.

According to the relevant person of Yinlong New Energy, although the energy density of lithium titanate is lower than that of Ferrous lithium phosphate and ternary lithium in theory, Yinlong has improved the energy density of lithium titanate battery by 40% through continuous research and development in the past three years, and still maintained the characteristics of 6-minute fast charging and 30-year cycle life.

With the support of relevant national policies, the broad prospects of new energy vehicles have made Yinlong New Energy taste the sweetness and accelerated the pace of expanding production capacity.

The reporter learned from many sources that in the past year, Yinlong’s factory is expanding rapidly, and its production capacity will be greatly improved through these new factories. In these days when the news of Gree’s acquisition of Yinlong came out, Yinlong expanded faster.

According to official data, Yinlong New Energy sold a total of 1,844 buses from January to August this year. From the overall sales situation of the industry, Yinlong New Energy ranked seventh in the industry in the first eight months, with a very rapid growth. Wei Yincang revealed that Yinlong New Energy Commercial Vehicle currently has an annual production capacity of 10,000 vehicles, which will reach 30,000 vehicles next year and 100,000 vehicles in 2020, and will also promote the production and manufacturing of passenger cars.

Regardless of the acquisition result of Gree, the large-scale construction investment of Yinlong New Energy is emerging. This time, Yinlong New Energy announced a number of major events, including the completion and commissioning of the fourth generation of high-energy-density lithium titanate nanomaterials and the fourth generation of high-energy battery, the completion and commissioning of fast-charging buses and logistics vehicles, the foundation stone laying of the fourth phase of Austrian Titanium and the inauguration of the Austrian Titanium Nanomaterials Research Institute.

"The peak of orders for new energy vehicles is in the second half of the year. At present, the company has received a large number of orders, but most of them are complete vehicles. There are few orders for batteries. At present, the batteries we produce will be supplied to our own vehicles first, and we will only consider selling them to the outside world after meeting the needs of our own vehicles. The batteries are in a state of sales exceeding supply. The production capacity of our batteries is still expanding. " Insiders of Yinlong New Energy told reporters.

He told reporters that at present, Yinlong new energy vehicles are mainly supplied to Beijing, Handan, Zhuhai and other cities. This year, they have entered Shenzhen, Anhui and other places, and there is a special sightseeing line in Beijing that uses pure electric double-decker sightseeing buses produced by Yinlong. "At present, the demand in the Beijing market is constantly expanding."

Wei Yincang said that the company plans to invest about 35 billion yuan in the next five years, complete about 650,000 new energy vehicles, achieve energy storage of more than 1500MWH, and the total output of power batteries exceeds 4 billion ampere hours. The total output of lithium titanate materials reaches 42,300 tons, and the output of charging stations is nearly 15,000 units.

Li Yuheng, a researcher of China Investment Consulting’s new energy vehicle industry chain, said: "At present, many domestic new energy vehicle manufacturers are looking for financial support, and Gree, with abundant capital flow, is a good partner. Gree Electric is currently the world’s largest specialized air-conditioning enterprise integrating R&D, production, sales and service. In order to increase revenue, Gree began to enter the new energy vehicle market. New energy vehicles have become the development direction of the future automobile market. Coupled with the government’s strong subsidies for new energy vehicles, Gree’s willingness to choose to transform into new energy coincides with Yinlong’s expansion needs. "

Accelerate the extension of upstream and downstream Gree wants to swallow the whole industrial chain.

After investigation, the reporter found that the opposite of the reporter’s factory is the assembly workshop of Yinlong new energy vehicle, and Yinlong also has a vehicle production and assembly workshop in Shijiazhuang. In other words, just in this production base in Handan, Yinlong New Energy can completely produce and deliver vehicles from material production and processing to vehicle assembly. This base covers almost the entire industrial chain of Yinlong New Energy Vehicles.

After Gree acquires Yinlong New Energy, it will control the whole industrial chain of new energy vehicles.

The reporter learned that Handan New Energy Automobile Industrial Park is part of the national strategic layout of Yinlong New Energy, and after the acquisition of Gree, Yinlong New Energy will continue to expand to meet the production of complete vehicles.

Yinlong New Energy said that in the future, Yinlong New Energy plans to build Chengdu New Energy Industrial Park in Southwest China and Lanzhou New Energy Industrial Park in Northwest China. After being acquired by Gree, Yinlong New Energy will continue to exert its strength in technology research and innovation in the future.

In the expansion of Yinlong New Energy Handan Industrial Park, the upstream and downstream production of new energy vehicles has been promoted to the first place, and Yinlong is accelerating the expansion of battery materials and charging piles.

Is it worthwhile to spend 10 billion yuan to buy?

After Gree announced that it would spend 10 billion yuan to acquire Yinlong New Energy, the acquisition disclosed by Gree triggered a heated discussion in the market, and the technical path and valuation of Yinlong New Energy were also widely discussed in the industry, with different views.

Some insiders believe that the suitability of lithium titanate battery technology selected by Yinlong New Energy needs to be verified. At present, lithium titanate has the weakness of low energy density and instability. However, some insiders have raised doubts about the high valuation of Yinlong New Energy in the acquisition of Gree.

Wei Yincang responded by saying: "There is a reason why Yinlong spent ten years paying 10 billion yuan in tuition fees to choose the lithium titanate route." He does not deny that Yinlong’s lithium titanate battery has the weakness of low energy density compared with other technologies such as lithium iron phosphate battery, but its advantages of wide temperature resistance, high safety, long life and fast charging and discharging speed deserve more attention. However, he said that according to relevant statistics, the average daily driving distance of passenger cars is about 50 kilometers, and about 90% of passenger cars are not used for long-distance operation.

Regarding the question that the market questioned the overvaluation of the acquisition, Wei Yincang said that the company is expected to achieve high sales growth this year and next year, and the company is not worried about this issue, because orders are already increasing rapidly.

"We hope that through the acquisition, more enterprises of 100 to 200 billion yuan will be born in China." Regarding the acquisition target, Dong Mingzhu, chairman of Gree Electric, said.

　　■ Heavy industry city and cultural tourism food, which had little connection, have repeatedly collided with the phenomenal online celebrity effect.

　　■ The Red Star Capital Bureau learned that during this year’s "May 1" holiday, Zibo Station has sent more than 240,000 passengers, an increase of 85,000 passengers over the same period in 2019; According to the 2023 May Day Blowout Data Report released by WeChat, during the May Day period, the tourism consumption in Zibo increased by 73% compared with April; Weibo’s data also shows that during the May Day period alone, Zibo made 70 hot searches on Weibo.

　　■ The recently released GDP of Zibo in the first quarter shows that the recovery of its consumer market is faster than that of the whole country and province. Shandong waist city, which once had a weak sense of existence, has become the top flow of the whole network. In addition to Zibo, Hegang and Liuzhou, both industrial cities, also performed well in the first quarter of this year.

　　■ Can online celebrity effect be a shortcut to help urban development? The interviewed experts told the Red Star Capital Bureau that the promotion of the city’s popularity will have various advantages for attracting investment and will also drive a certain inflow of talents. However, it remains to be seen whether the simple "online celebrity effect" can drive GDP.

　　it is not unique

　　Hegang, a city in online celebrity, also performed well before Zibo’s economic recovery.

　　After the barbecue, Zibo’s first-quarter report card attracted social attention — — The recovery of its consumer market is faster than that of the whole country and province.

　　According to official data of Zibo, the city’s GDP reached 105.77 billion yuan in the first quarter, up 4.7% year-on-year. In the first quarter of Zibo, the consumer market showed obvious improvement in economic development, and the recovery momentum was strong. In the first quarter, the city’s total retail sales of social consumer goods reached 31.36 billion yuan, up 8.3% year-on-year, 2.7 and 2.5 percentage points higher than that of Shandong province and the whole country respectively. Among them, the sales (turnover) of wholesale, retail, accommodation and catering above designated size increased by 9.5%, 15%, 16% and 25.2% respectively, which were 4.7, 14.9, 7.2 and 19.8 percentage points higher than those in January and February respectively.

　　Zibo’s GDP growth in the first quarter was not entirely due to the sudden popularity of barbecue in Zibo. Pan Helin, co-director and researcher of Digital Economy and Financial Innovation Research Center of International Joint Business School of Zhejiang University, told Red Star Capital Bureau that the barbecue explosion in Zibo started in March this year, mainly in April and May, and Zibo’s GDP will be even more brilliant in the second quarter. At the same time, Zibo’s local finance and local economy have blossomed, and the improvement of local business environment can drive Zibo to have a "flywheel effect".

　　Coincidentally. Hegang, another "online celebrity city", unexpectedly hitched a ride in the Internet era because of the price of cabbage for 20,000 or 30,000 suites, and gained a lot of traffic. In the first quarter of this year, Hegang’s data was also very bright. From January to March, the GDP of hegang, Heilongjiang Province was 7.46 billion yuan, with a growth rate of 8.5%, which was higher than the provincial average (5.1%) and ranked first among 13 prefecture-level cities in Heilongjiang Province.

　　A revelation

　　Can online celebrity Effect Drive the Development of Resource-exhausted Cities?

　　Zibo and Hegang, both important old industrial cities in China, played an important role in the early development of new China, and are now also listed as "resource-exhausted cities".

　　"The last time Zibo was so hot, it was the time of Qi." Netizens commented on Zibo’s long-standing "marginalization".

　　In fact, besides being the capital of Qi, Zibo is an old industrial base with a history and an important petrochemical base in China.

　　According to Xinhua News Agency, Zibo has a modern industrial history of more than 100 years. It is the only city in China that covers three types: resource-exhausted cities, independent industrial and mining areas and old industrial bases.

　　For today’s Zibo and Hegang, industry is still the main driving force for their development.

　　In 2022, the tertiary industrial structure of Zibo was 4.3: 49.8: 45.9; In 2021, the ratio was 4.3: 49: 46.6; Comparatively speaking, the proportion of the secondary industry has increased compared with 2021, the proportion of the tertiary industry has declined, and the primary industry has not changed. The proportion of secondary industry in Zibo ranks second among 16 cities in Shandong, second only to Dongying (57.8%); According to the data of the first quarter, although the proportion of the secondary industry declined slightly (48%), it still occupies half of the country, so it can be seen that "industrial city" is still the biggest background color of Zibo.

　　Compared with Harbin, an old industrial base in Northeast China, Hegang’s industrial genes are still strong. In 2022, the proportion of three industries in Harbin was 12.2: 23.4: 64.4, and it has been transformed into a service-oriented city with a low proportion of industries. In 2022, the proportion of the three industries in Hegang was 25.5: 38: 36.5. In addition, the industrial added value of hegang will increase by 9% in 2022, which is 8.2 percentage points higher than the provincial average, ranking first in the province.

　　It remains to be seen how much the online celebrity label can bring to industrial cities. Liang Ma, a researcher at the National Development and Strategy Institute of Renmin University of China and a professor at the School of Public Administration, told the Red Star Capital Bureau that there will be short-term effects, which will improve the development of the service industry, including retail and catering, but whether these can be sustained remains to be seen.

　　Where is the road?

　　How to stimulate long-term vitality?

　　Liuzhou path is difficult to copy.

　　Zibo’s barbecue is on fire. How to stimulate the city’s longer-term economic vitality is a real proposition outside the barbecue label.

　　Zibo is not the first industrial city to put on the "Red Label of Food Network". Liuzhou, the hometown of snail powder, is the largest industrial city in Guangxi, and its data in the first quarter of 2023 also shows the strength of the tertiary industry in Liuzhou. The added value of the primary industry was 2.444 billion yuan, a year-on-year increase of 4.4%; The added value of the secondary industry was 29.207 billion yuan, an increase of 3.1%; The added value of tertiary industry was 41.603 billion yuan, up by 4.1%. The added value of tertiary industry accounts for 3.3: 39.9: 56.8, and the tertiary industry accounts for nearly 60%.

　　Although it is an industrial city like Zibo, Liang Ma believes that Liuzhou has stronger "vitality". "Snail powder is sold through e-commerce, and its related industries, such as planting, production, sales, marketing, etc., have now started on a scale and formed a brand, and its continuous influence will be further amplified." Snail powder is an industry that can radiate without coming to Liuzhou. "Liuzhou has found a sustainable path, and now it doesn’t need the online celebrity label, because everyone has formed a brand recognition, and a group of consumers have the consumption habit of buying snail powder." But barbecue in Zibo is not yet. Liang Ma explained that Zibo’s supporting facilities are barbecue-centered, and you need to go to the local place to punch in to create output value.

　　Ren Zeping, an economist, said that in recent years, people from all walks of life in Shandong have obviously improved their sense of crisis and enterprising spirit for development. Zibo is a typical case. Ren Zeping believes that innovation drives high-quality development and Shandong lacks new economy, new industries, new technologies and new ideas. I hope Shandong can seize the new opportunity of the new round of industrial technology revolution and realize lane change and overtaking.

　　Fortunately, despite the label of online celebrity, Zibo and Hegang, as industrial cities, are also actively seeking the road of transformation.

　　Last July, China Graphite Group (02237.HK) was listed in Hongkong, becoming the first listed company in Hegang. Zibo regards the "four strong" industries of new materials, intelligent equipment, new medicine and electronic information as the main direction of the transformation of old and new kinetic energy in industry — — It is proposed that by 2025, the added value of the "four strong" industries will account for 55% and 42% of the regional GDP respectively, and the modern service industry will account for 60% of the added value of the service industry.

　　At the same time, with the help of online celebrity label, both Zibo and Hegang have made full efforts in attracting investment this year.

　　Online celebrity effect is favorable for attracting investment, which is the most important aspect that Liang Ma thinks. "The popularity has increased, so that those who may not have paid attention to the industrial structure of this city in the past are willing to invest in attracting investment. It may also promote the development of its own traditional industry or manufacturing industry, and it will also bring about this increase in output value. "

　　In addition, the advantage lies in talent attraction. "The popularity of the city has increased, and everyone may also be concerned about investment or employment opportunities. These two aspects are more critical." Liang Ma pointed out that barbecue brings more soft power to Zibo, making barbecue an opportunity to ride the wind, continuously strengthening city publicity and brand promotion, and keeping its popularity at a high level, which is very likely for Zibo to become a new second-tier city.

　　　　　　 CCTV News:In Quzhou City, Zhejiang Province, there is a post-90s youth named Mao Hantao. He suffers from congenital cerebral palsy, with muscular atrophy in both legs and difficulty in walking. The fingers of both hands are almost stiff, and only the index finger of his right hand can move. Although his IQ is normal, he dropped out of school at home after graduating from junior high school because of his health and other reasons.

　　　　　　 At school, Mao Hantao was good at writing. At home, he sometimes made up some short stories about his feelings. He used his only movable finger to type. In this way, he spent nine years, and has created more than 2 million words of novels so far, knocking out a sky for his writer’s dream.

　　　　　　 Two or three crosses wrote two million words in one minute.

　　　　　　 Mao Hantao is a post-90s generation. Only his right hand is flexible, and his left hand can’t type at all. So he can only knock with one thumb, maybe twenty or thirty words a minute. He keeps writing novels, changes them if he is not satisfied, and then deletes them and rewrites them if he is not satisfied. Delete write, write delete like that … … Then step by step to achieve their own satisfactory state.

　　　　　　 At that time, when I started writing, I didn’t intend to publish it at all. Then I wrote about 500,000 to 600,000 words and posted them on that Baidu Post Bar. Mao Hantao had several QQ groups, and people in their QQ groups said, Your writing is not bad, and your writing is not bad. Why not publish it … … Then he wanted to try it, and then he went to the domestic novel website and published it on their platform, with about 38 thousand hits. After the novel was written, he got the money, and the manuscript fee was 1400 yuan. After getting it, Mao Hantao was also happy all day.

　　　　　　 Mao Xiaotao’s father Mao Xiaobo: "It is also his own hobby that children can write now. We also feel very happy. We also hope that he can stick to his hobby and change his life through his hobby."

　　　　　　 Write your own shadows and dreams into the novel.

　　　　　　 We might as well read a short paragraph: "Time has passed, and in a blink of an eye, things have changed, and things have changed … … Everything, unconsciously, is branded in everyone’s heart — — It’s called the brand of time. One man, one sword. No one knows how long this man has been by this well … … Maybe even he must have forgotten? "

　　　　　　 This is a fragment from Mao Hantao’s novels. Mao Hantao feels that his style of writing has the shadow of his idol Jin Yong, while the hero has his own shadow. He said that the protagonist is a slow learner, but he is very diligent, and finally he is recognized by the underworld and the divine world. Here are his shadows and dreams.

　　　　　　 Mao Hantao said that the protagonists in his novels usually have one thing in common, that is, the little people at the bottom of society are not good at anything and can’t do anything well, and later they succeeded through hard work. Just like himself. Now he has finished a novel with a length of 1.29 million words, which is definitely not the end of Mao Hantao’s dream. He is writing several novels at the same time, including basketball and other themes. Mao Hantao said, "I am an upward young man, and I am willing to strive for the top. I also hope that I can become a writer who can support my family, and I hope that girls will like me. Although this is a bit difficult, I will work hard for it." May his dream come true.

The peach blossoms and magnolias downstairs seem to have all opened overnight, with pink smiling faces. I opened the window, and the spring breeze brought their faint fragrance.

For China people, each season has its own unique flavor, which reminds us of the appearance of time and the smell of home. Of course, spring also has flavor, such as peach blossom, pear blossom, magnolia flower, grass, earth and wild vegetables. Changing seasons and eating at the right time are the aesthetics of life formed by China people in getting along with nature. Everything grows, and now is the best season to eat wild vegetables in a year.

Chun feng Hua Cao Xiang

I remember when I was young, every season, the temperature was getting higher and higher, the sun was shining on my body, and my cotton-padded clothes could not be worn. My father would lead me to the riverbank of the Grand Canal near my hometown, half for an outing and half for finding wild vegetables. Under the river bank, the water surface is much wider, and the wind blowing from the canal water surface smells of reeds. On the riverbank, the grass has already passed the ankle, and the fragrance of plants and the moist mud smell are floating in the air and drilling into the nostrils. Our bodies seem to be light at once, throwing off our hands and feet and running into the grass. Gouqitou, shepherd’s purse, purslane, Artemisia selengensis, dandelion, and some wild vegetables that I can’t name are getting higher and higher day by day. These wild vegetables that have survived the winter seem to contain the aura of heaven and earth in their bodies, and their roots are full of vigor.

Artemisia selengensis grows by the water, which is a kind of wild vegetable with a "very fragrant" taste. Wang Zengqi praised it as "sitting by the river and smelling the newly rising spring water when eating". My hometown is not far from Gaoyou, Wang Zengqi’s hometown, and the types of wild vegetables are also very similar. He said, "Lycium barbarum is everywhere … The local Lycium barbarum is not used as medicine, which is probably not as good as that produced in Ningxia. Lycium barbarum is a perennial plant. In spring, young leaves appear, that is, gouqi head. "

My father’s favorite is the cold gouqi head. After washing it, blanch it with boiling water, chop it up, sprinkle some salt, and sprinkle it with balsamic vinegar and sesame oil before serving. The first taste is slightly bitter, but when swallowed, the throat is somewhat sweet, and that unique fragrance is hard to forget. We will miss this taste every few days. As the temperature keeps rising, the gouqi head becomes darker in color, and its taste is no longer as fresh as it was at the beginning. We will try to pick as many as possible, put them in bamboo plaques when we get home, dry them in the sun, and make stuffing with meat in autumn and winter, making buns and jiaozi, which is another kind of delicious food.

Human fireworks

It is said that spring is three points, and one point is in the wild. Another spring has come, and the breeze reminds people of the aroma of wild vegetables.

Spring is the best time to taste the fireworks. "The peaches and plums in the city are worried about the wind and rain, and the shepherd’s purse flowers in the stream head in spring." "I don’t know how Malan enters the morning cup, but it’s like oats shaking the spring breeze." "The bamboo shoots of Artemisia Polygonum Thunb try the spring dish, and the taste in the world is pure joy." Poets are probably the first to discover the "beauty of wild vegetables" and record them.

After the fright, the variety of wild vegetables suddenly increased, such as shepherd’s purse, spring bamboo shoots, purslane, Toona sinensis, mother-in-law and Malantou. In Nanjing, Jiangsu Province, with the continuous improvement of epidemic prevention and control situation, citizens’ lives gradually returned to daily life. In Kexiang vegetable market, Nanjing citizens who love wild vegetables are choosing seasonal wild vegetables that have just been listed to enrich their dining tables. This year, more merchants choose "cloud selling" to move wild vegetables originally placed in farmers’ markets to the Internet. People can bring home the spring flavor in the fields with their fingers at home and taste the spring without leaving home.

At the beginning of March, farmers in Linyi, Shandong Province began to sell various seasonal wild vegetables through WeChat and Taobao stores. In the photos he took, the roots of wild vegetables were still covered with wet soil, and the aroma seemed to come out through the screen. "A lot of people who come to buy are old customers and want to taste fresh." "Yue Yue Xian" told reporters that some of these wild vegetables were dug in the wild by themselves, and some were bought from nearby villagers. "In the past, these wild vegetables were scattered in the fields, but now they have become people’s’ good hearts’, and the price of a catty is in 6 yuan-8 yuan."

"In the past, we ate wild vegetables for food, but now it is for health." Xu Congjun, a Beijing resident, feels that the status of wild vegetables on the dining table of China people has changed dramatically in the past few decades. Now people eat wild vegetables, which is not only delicious, but also pleasant.

The best taste is in my hometown.

In the past few years, I always took my children to the wild to see flowers and grass every spring. This spring, in the days of staying at home, taking children to know wild vegetables and feel the taste of spring in the kitchen has become the most relaxing time of our day. After simple cooking, two or three kinds of wild vegetables were put on the table in a green way, which was refreshing and refreshing. We completed the spring outing on the tip of our tongue again and again.

Zhang Ye chose to make a pickle to remember this spring. Spring bamboo shoots that have just been listed, with fresh meat and ham, can be simmered slowly and bubbled, which can make people "fresh off their tongues". "Every spring, I will cook pickled vegetables several times." This is Zhang Ye’s favorite hometown dish, who has lived in Beijing for many years. "People’s tastes are hard to change, and the taste of hometown is deeply rooted. Even after years, just a trace is enough to soothe the heart. The moment I tasted the soup, I really felt that spring was coming. "

In everyone’s mind, "hometown" is probably the most resonant word. The longer you leave home, the stronger your feelings for your hometown will be.

"Shepherd’s shepherd’s purse is a wild vegetable that people in eastern Zhejiang often eat in spring. Needless to say, people in the countryside can eat it at any time as long as there is a backyard in the city. Women and children each take a pair of scissors and a’ seedling basket’ and squat on the ground to search. It is an interesting game job. At that time, the children sang:’ shepherd’s purse Malantou, my sister married at the back door.’ Later, some villagers in Malantou brought it to the city for sale, but shepherd’s purse is still a kind of wild vegetable, which needs to be picked by themselves. "Zhou Zuoren in the hometown of wild vegetables, a genre painting in eastern Zhejiang as slowly unfolded in front of our eyes, dotted with the most ordinary wild vegetables. Hometown food has also appeared in Wang Zengqi’s works many times. He once wrote about hometown Artemisia selengensis, Lycium barbarum, shepherd’s purse, purslane and so on. These wild vegetables not only have the spring scenery of hometown, but also have the taste of hometown.
