Since September, Nanjing Children’s Hospital has received nearly 400 cases of influenza, which ushered in a small peak of influenza treatment.

Recently, the National Health and Wellness Commission held a press conference, suggesting that with the cold weather, it is the epidemic season of respiratory infectious diseases. Wang Huaqing, chief expert of immunization program of China CDC, suggested that influenza vaccine should be vaccinated before the end of October.

He mentioned that vaccination is usually better before the flu epidemic season, and it is generally recommended to complete vaccination before the end of October. If the vaccination is not available before October for various reasons, the vaccination should be completed as soon as possible in the follow-up so that the effect of the vaccine can be better played. Because it takes about 2 to 4 weeks for the vaccine to have an effect.

How to choose the flu vaccine? Who should be vaccinated the most? Who doesn’t recommend vaccination? About 13 questions about influenza vaccine, Jiangsu CDC authorities answered questions-

Q1. Why should I get the flu vaccine?

Influenza is not a common cold, but an acute respiratory infection caused by influenza virus. According to the estimation of the World Health Organization, influenza can cause 3 million to 5 million severe cases and 290,000 to 650,000 respiratory diseases-related deaths worldwide every year. Vaccination against influenza is an effective means to prevent influenza and reduce influenza-related severe illness and death.

Q2. What are the types of influenza vaccines? How should I choose?

There are inactivated vaccines (including split vaccines and subunit vaccines), attenuated live vaccines and recombination vaccines. According to the components contained in the vaccine, it can be divided into trivalent and tetravalent influenza vaccines. Compared with trivalent influenza vaccine, tetravalent influenza vaccine strains have added a pedigree of influenza B. Inactivated vaccine was injected intramuscularly, and attenuated live vaccine was sprayed intranasally.

The influenza vaccines approved for marketing in China this year include trivalent inactivated vaccine, tetravalent inactivated vaccine and trivalent attenuated live vaccine. People aged ≥6 months can be vaccinated with trivalent or tetravalent inactivated vaccine, and people aged 3~17 can also choose trivalent attenuated live vaccine. For people who can be vaccinated with different types of vaccine products from different manufacturers, they can voluntarily vaccinate any kind of influenza vaccine, and there is no priority recommendation.

Q3. When should I get the flu vaccine?

Usually, the antibody can reach the protective level after 2~4 weeks of influenza vaccination. The time and duration of the annual peak of influenza activity are different in different parts of China. It is suggested that the recipients should be vaccinated with influenza vaccine one month before the influenza epidemic season. If the vaccination is not completed before the arrival of the epidemic season, it can be vaccinated throughout the epidemic season.

Q4. Where can I get the flu vaccine?

Influenza vaccines can usually be vaccinated in community health service centers or hospitals. Vaccination units may vary from place to place, so please consult the local health administrative department for details.

Q5. Who needs influenza vaccination?

People who are over 6 months old and have no vaccination contraindications should be vaccinated against influenza.

Combined with the epidemic situation of influenza and the prevention and control strategy of multi-disease prevention, the harm of influenza is reduced as much as possible, and the following key and high-risk groups are recommended to be vaccinated in time:

① Medical personnel, including clinical rescue personnel, public health personnel, health and quarantine personnel, etc.

② Older people over 60 years old;

③ people suffering from one or more chronic diseases;

(4) Vulnerable people and employees in gathering places such as old-age care institutions, long-term care institutions and welfare homes;

⑤ Children aged 6 ~ 59 months;

⑥ Family members and caregivers of infants under 6 months old;

⑦ Crowds in key places such as kindergartens, primary and secondary schools and supervision places.

Q6. Who can’t be vaccinated?

① Those who are allergic to any ingredients contained in the vaccine (including auxiliary materials, formaldehyde, cracking agents and antibiotics) or who have had a history of severe allergy to any kind of influenza vaccination are prohibited from vaccination;

② Patients suffering from acute diseases, severe chronic diseases or acute attacks of chronic diseases, as well as patients with fever, are advised to be vaccinated after recovery or stable control of their condition;

③ Patients with Guillain-Barre syndrome within 6 weeks after previous influenza vaccination are advised to be evaluated by doctors before considering whether to vaccinate.

It should be noted that the following populations are prohibited from receiving live attenuated vaccines:

① Persons with low immune function due to drug use, HIV infection and other reasons;

② Children and adolescents who have been treated with drugs containing aspirin or salicylic acid for a long time;

③ Children with asthma aged 2-4 years;

4 pregnant women;

⑤ Those with a history of Guillain-Barre syndrome;

⑥ Those who used antiviral drugs such as oseltamivir and zanamivir 48 hours before inoculation, or those who used palamivir 5 days before inoculation, or those who used balosevir 17 days before inoculation.

Q7. What should I pay attention to after influenza vaccination?

After vaccination, you need to stay in the vaccination unit for half an hour. If there is no abnormality, you can leave on your own. After returning home, pay attention to rest, eat lightly and avoid strenuous exercise. If there is any abnormal phenomenon, you can consult and report to the vaccination doctor and go to the hospital if necessary.

Q8. Why do you have to get the flu vaccine every year?

First of all, influenza virus is prone to mutation. The World Health Organization proposes the recommended components of influenza vaccine for the next epidemic season every year based on the results of global influenza surveillance, and the influenza virus strains targeted by influenza vaccines may be different in different years. Secondly, the immunity of influenza vaccination will gradually weaken over time. Therefore, in order to provide more effective protection, it is recommended to vaccinate against influenza every year.

Q9. Is it safe to get the flu vaccine? Are there any side effects?

Influenza vaccination is safe, but like other medical products, influenza vaccine may also have adverse reactions. The common adverse reactions of influenza vaccination include local reactions (redness, swelling, induration, pain, burning sensation, etc.) and systemic reactions (fever, headache, dizziness, lethargy, fatigue, myalgia, general malaise, nausea, vomiting, abdominal pain, diarrhea, etc.). These adverse reactions are usually mild, and usually disappear on their own within a few days, with few serious reactions.

Q10. Can people with egg allergy be vaccinated against influenza?

Egg allergy is not a taboo in People’s Republic of China (PRC) Pharmacopoeia (2015 and 2020 editions). The current pharmacopoeia stipulates that the content of ovalbumin in inactivated influenza virus vaccine should not be higher than 250ng/ dose, and the content of ovalbumin in split vaccine should not be higher than 200ng/ml. There is no description of attenuated live vaccine at present. The measurement of egg protein content in commonly used influenza vaccines in China shows that the highest content is not more than 140ng/ml. At the same time, foreign scholars’ research on the inactivated vaccine or attenuated live vaccine inoculated to those who are allergic to eggs shows that no serious allergic reaction has occurred. Therefore, egg allergy is not recommended as a taboo for influenza vaccination.

Q11. Won’t you get the flu after vaccination?

In most years, influenza vaccine has a good match with influenza epidemic strains and has good protection. However, there is also a certain probability that the strain of influenza vaccine does not match the epidemic strain, which further affects the protection effect of influenza vaccine. In addition, influenza vaccination can only prevent influenza caused by influenza virus, but can not prevent such symptoms caused by infection of pathogens other than influenza virus (such as parainfluenza virus, adenovirus, etc.).

Q12. Can I get the flu vaccine while using antiviral drugs?

Inactivated influenza vaccine can also be inoculated during the prevention and treatment of influenza antiviral drugs. Preventive or therapeutic use of anti-influenza drugs will affect the immune effect of attenuated live influenza vaccine, and it is not recommended to use both at the same time. If you have used any other vaccines or drugs, including over-the-counter drugs, please inform the vaccination doctor before vaccination.

Q13. Can the flu vaccine be vaccinated at the same time as other vaccines?

Inactivated influenza vaccine, other inactivated vaccines and attenuated live vaccines, such as enterovirus 71 vaccine, pneumococcal vaccine, herpes zoster vaccine, chickenpox vaccine, measles vaccine and DTP vaccine, can be inoculated in different parts at the same time.

There is limited research evidence that live attenuated influenza vaccine and other vaccines are vaccinated at the same time. After vaccination with live attenuated influenza vaccine, other live attenuated vaccines can only be vaccinated after an interval of more than 4 weeks. (Wang Tian)

The commendation meeting of the 2016 Shanghai Key Project Practical Meritorious Competition was held this morning (January 12). Before the meeting, Han Zheng, secretary of the Shanghai Municipal Party Committee, met with representatives of advanced collectives and individuals. Han Zheng said,2017 is the year of deepening the "Thirteenth Five-Year Plan". It is hoped that advanced collectives and individuals will play a leading and exemplary role, always adhere to safety first, quality first, management first, science and technology leading, and make greater contributions to building Shanghai into a more beautiful city and making people’s lives happier.

On the morning of January 12th, Han Zheng, secretary of the Shanghai Municipal Party Committee, met with representatives of advanced collectives and individuals. The pictures in this article are all Chen Zhengbao’s pictures.

Shanghai leaders Yang Xiong, Wu Zhiming, Ying Yong, Yin Hong, Xue Chao and Li Yiping, and Shanghai Garrison Political Commissar Ma Jiali attended the meeting.

On behalf of the Shanghai Municipal Party Committee, the Municipal People’s Congress, the Municipal Government and the CPPCC, Han Zheng congratulated the advanced collectives and individuals who were commended for their meritorious deeds in key projects, paid tribute to the vast number of urban builders and managers who fought in the front line all the year round, and expressed gratitude to the general public who understood, cared for and supported urban construction and major projects. He said that at this time of the year, we review the course of Shanghai’s key projects’ practical meritorious deeds competition, feel the hardships and share the joy of success. Since China’s reform and opening-up, especially since Pudong’s development and opening-up, Shanghai’s key projects have been closely focused on making up the shortcomings and facing the future development, constantly pushing forward, laying a solid foundation for the city’s economic and social development. This year is the year of deepening the 13th Five-Year Plan. According to the requirements of the central authorities, Shanghai is striving to be the vanguard of national reform and opening up and the pioneer of innovation and development, and is striving to basically build the "four centers" and a socialist modern international metropolis by 2020. The field of urban construction shoulders heavy responsibilities. Hope that advanced collectives and individualsAlways adhere to safety first, quality first, safety is the bottom line, and quality is life. We must always tighten the string of safety and continue to play a benchmark and leading role in key projects and practical projects with the world’s advanced level as the standard. Always adhere to management as the priority and science and technology as the guide, put management in a more important position to ensure safety and quality, highlight scientific and technological innovation, and improve the quality of the city. Always adhere to the people-friendly and civilized construction, and try to minimize the impact on the orderly operation of the city and the normal life of the citizens during the construction process.

At the commendation meeting, Yang Xiong said that last year, the achievements of major projects and practical projects in this city were gratifying, the shortcomings of urban management were remarkable, and the task of aiding Xinjiang was successfully completed, achieving the "Thirteenth Five-Year Plan" and "a good start". This year is an important year for implementing the 13th Five-Year Plan and deepening the structural reform on the supply side. Facing the new situation, we should conscientiously implement the general tone of striving for progress while maintaining stability, sum up experience, blaze new trails, roll up our sleeves and go all out to complete various construction tasks.

"Safety and quality are the lifeline of major engineering construction and must always be put in the first place." Yang Xiong pointed out that it is necessary to pay strict attention to construction safety, take effective measures, consolidate the main safety responsibilities of construction, survey, design, construction and supervision, pay close attention to key construction links, and strengthen the safety control of major risk sources. It is necessary to continuously improve the quality of the project, adhere to the international first-class benchmarking, comprehensively consider the design, construction and operation, adopt more advanced international quality standards, vigorously carry forward the craftsman spirit, and strive to create more excellent projects. To improve the level of civilized construction, the construction unit should further strengthen the overall awareness, focus on improving internal management, reduce related social costs, and minimize the impact of engineering construction on the city. The construction of rail transit stations should strive to occupy less roads and return them early. It is necessary to strengthen dust control on construction sites and roads, and urge transportation enterprises to reduce "leakage" in muck transportation. We should persist in scientific and technological innovation and promote the transformation and upgrading of the construction industry. To become an important carrier of scientific and technological innovation, major projects should promote prefabricated buildings in major projects throughout the city, and constantly increase the proportion of prefabricated components used in each project. It is necessary to speed up the popularization of building information model technology (BIM), and establish and improve the matching project approval mode and standard system. It is necessary to make more use of new technologies such as the Internet of Things and big data to explore intelligent life cycle management of buildings.

Shanghai leaders Ying Yong and Xue Chao, and Yi Li Pinghe Garrison leader Ma Jiali attended the meeting. A number of advanced collectives and individuals who made outstanding contributions to the construction of major projects and practical projects in this city in 2016 were commended.

It is reported that in 2016, 122 major engineering projects in the city were comprehensively promoted. By the end of December of that year, a total investment of 128.01 billion yuan had been completed, and 123.6% of the plan was completed at the beginning of the year.

　　On Tuesday, local time, US stocks finally got rid of the light market trend for more than a week, but unfortunately it was not a big rise but a big drop. The three major indexes closed down across the board, with the Dow down more than 300 points and the Nasdaq down 2%.

　　On the one hand, the power of the earnings season began to show, and giants such as McDonald’s and UPS warned that the macroeconomic prospects were not good in the earnings report. On the other hand, the deposits of Daiwa Bank in the United States dropped by 40%, and UBS’s net profit in the first quarter halved, all of which highlighted that the banking crisis had not completely subsided and the market risk aversion was ignited.

　　On Monday, the First Total Bank disclosed that even though Wall Street giants had jointly deposited 30 billion dollars, they lost over 70 billion dollars in the first quarter of this year alone. At the end of the first quarter, the deposit figure was only $104.5 billion, far below the $136.6 billion expected by analysts.

　　The first total and the bank lost 49.38% of its market value on Tuesday. In the news, the media reported that the bank was going to sell "50 billion to 100 billion dollars" of long-term assets to solve the mismatch problem. It is reported that Biden administration officials have been keeping in touch with Daikyo Bank in recent days, and the White House is increasingly worried that there is not much time left for Daikyo Bank to appease investors and depositors, but American policy makers are not worried that risks may spread further among banks.

　　It is worth noting that due to various indications that there are still many risk factors in the market, traders no longer bet 100% that the Fed will continue to raise interest rates before the middle of this year. According to the observation tool of the Federal Reserve, the probability of raising interest rates by 25 basis points in May fell to 81.5%, compared with 90.5% the previous day.

　　However, for technology stocks, the financial reports of Microsoft and Google have slightly eased some market concerns. AI and cloud services helped Microsoft’s financial report exceed expectations, with revenue of $52.9 billion, higher than analysts’ expectations of $51.03 billion; Earnings per share were $2.45, higher than analysts’ expectations of $2.24.

　　The interest rate swap contract of the Federal Reserve in June currently reflects that the benchmark interest rate of the central bank is only 20 basis points higher than the current effective federal funds rate, which implies that the possibility of raising interest rates in one of the next two FOMC meetings is about 80%, while it was almost certain that the Fed would raise interest rates in May.

　　The debt ceiling deadlock is hard to solve. The White House says Biden will veto the Republican bundled spending reduction plan.

　　The Republican proposal put forward by House Speaker McCarthy requires that the debt ceiling of $1.5 trillion be raised and the future total government expenditure be reduced by $4.5 trillion. On Tuesday, the White House said that the debt ceiling must be solved without any conditions.

　　Xinhua News Agency, Beijing, December 18th: Four Questions about Vaccination for the Elderly — — Investigation report from the front line of epidemic prevention and control

　　Xinhua news agency reporter

　　90.37%, which is the proportion of people who have completed the whole vaccination of Covid-19 vaccine in China; 86.6% and 66.4%, respectively, are the proportion of people over 60 years old and over 80 years old who have completed the whole vaccination.

　　With the weakening of pathogenicity in Omicron, the popularization of vaccination and the accumulation of prevention and control experience, China’s epidemic prevention and control is facing a new situation and new task.

　　The comprehensive group of joint prevention and control mechanism in the State Council optimized the implementation of the "New Ten Articles" of epidemic prevention and control, and accelerated the Covid-19 vaccination for the elderly. The Central Economic Work Conference just held also proposed that we should optimize epidemic prevention and control measures according to the current situation, conscientiously implement various measures for epidemic prevention and control in the new stage, focus on the prevention and control of the elderly and groups suffering from basic diseases, and strive to maintain health and prevent severe diseases.

　　Why should we emphasize the necessity of vaccination for the elderly? Does vaccination work? Is vaccination safe? The reporter launched an investigation on the front line of epidemic prevention and control.

　　On December 15th, at the COVID-19 Vaccination Point in Zhongguancun Street, Haidian District, Beijing, medical staff vaccinated the elderly with COVID-19 vaccine. Xinhua News Agency reporter Ren Chaoshe

　　How necessary — — The defense line of the elderly group is relatively fragile.

　　Li Cuiwen, 78, lives in a remote village in the central province. Children are all in the city. On weekdays, they send rice flour oil, and the vegetables are grown in their own fields. They go to the town to catch a gathering once a month.

　　"I can’t see outsiders." Li Cuiwen and his wife have not been vaccinated with Covid-19 vaccine so far. "Is everyone fighting, even if we don’t fight, we can’t infect us?"

　　Li Cuiwen is not the only one who has similar questions. In this regard, Xia Gang, director of the Department of Health and Immunity of the National Bureau for Disease Control and Prevention, said that there are quite a few disabled and semi-disabled people in China who live at home for a long time and rarely go out, but they may still be infected when they are accompanied by relatives or visited by relatives.

　　Compared with the previous strains in Covid-19, the pathogenicity of Omicron is weakening, but the infectivity is becoming stronger. The extremely fast transmission speed is multiplied by China’s huge population base. Even if the severe illness rate and mortality rate are already very low, the number of people at risk should not be underestimated.

　　During the epidemic in Shanghai from March to June this year, compared with those who were not vaccinated, the death risk of people over 60 years old who completed the booster immunization was reduced by 98.08%, and that of people over 80 years old who completed the booster immunization was reduced by 95.83%.

　　At the press conference of the State Council Joint Prevention and Control Mechanism held recently, Xia Gang introduced that according to the research, if the elderly over 80 years old are not vaccinated with one dose of vaccine, the risk of death after being infected with Covid-19 is about 14.7%; If one dose of vaccine is inoculated, the risk of death will be reduced to 7.16%; If three doses of vaccine are inoculated, the risk of death will be reduced to 1.5%.

　　"I strongly call for accelerating the vaccination of vaccines, especially for vulnerable people such as the elderly." Zhong Nanshan, an academician of China Academy of Engineering, said.

　　On December 15th, two groups of communities were prepared in Kangmei Street, Liangjiang New District, Chongqing, and the medical staff of the community health service center checked the information of the elderly who had been vaccinated with COVID-19 vaccine. Xinhua News Agency reporter Huang Weishe

　　How effective is it — — Survey data show that the risk of severe illness can be greatly reduced.

　　In Chongqing, Zhang, an 84-year-old rehabilitation patient, told reporters that he suffered from many basic diseases such as hypertension and diabetes. He completed the third dose of vaccination in July this year and was infected with Covid-19 in November. After treatment, his condition was effectively controlled and he has been discharged.

　　On December 16th, in the home of residents in Honghe Road Community, Zhongshan Road Street, Yongchuan District, Chongqing, the mobile vaccination team conducted pre-vaccination consultation and physical examination for the vaccinated elderly. Xinhua News Agency reporter Huang Weishe

　　"Studies at home and abroad confirm that vaccination has a good effect in preventing serious illness and death." Xia Gang said that after being infected with Covid-19, the elderly are more likely to develop into severe illness or even death, and Covid-19 vaccine will benefit the most.

　　At most, beijing ditan hospital has treated more than 100 COVID-19 patients over 80 years old. Chen Xiaoyou, vice president of the hospital, said that the vaccination rate of these elderly patients is generally low, and the incidence of severe illness after illness is relatively high, especially in COVID-19, which is aggravated by basic diseases.

　　COVID-19 Designated Treatment Hospital in Hefei — — Ding Zhen, director of the Department of Respiratory and Critical Care Medicine of Hefei Binhu Hospital, told the reporter: "For some elderly people with basic diseases such as hypertension and diabetes, Covid-19 infection may aggravate the inflammatory reaction in the body, aggravate the condition of the basic diseases, and even lead to multiple organ failure."

　　Ding Zhen introduced that from the observation of their clinical treatment, the elderly who have been vaccinated are less likely to get worse and the time required for nucleic acid to turn negative is shorter.

　　In October, 2022, The Lancet Infectious Diseases published a research result based on the real-world vaccination population, which was released by the relevant research team of School of Public Health, Li Ka-shing Medical College, HKU. The study shows that the effective rate of preventing severe illness is about 70% for the elderly over 60 years old who are vaccinated with two injections of domestic inactivated vaccine, and the effective rate of preventing severe illness is over 95% after the third injection of intensive immunization.

　　On December 13th, in the Community Health Service Center of Baihedong Street, Liwan District, Guangzhou, medical staff made information entry and consultation for the elderly residents who came to receive COVID-19 vaccine. Xinhua News Agency reporter Deng Hua photo

　　Security geometry — — Make clear the taboo of vaccination and ensure safety to the greatest extent.

　　In the past few days, in Huanghuagang Street, Yuexiu District, Guangzhou, the average number of elderly people who take the initiative to consult and make an appointment for vaccination has exceeded 300, which is significantly higher than usual.

　　Yu Shu and Ye Yi, who live in Nongben community, had concerns about vaccination because of their basic diseases. After many door-to-door publicity by community workers and volunteers, Ye Yi was vaccinated under the health monitoring of doctors, and there were no adverse reactions. The next day, Uncle Yu also completed the vaccination. "Now I know that the previous concerns are redundant."

　　On December 12th, in Guanggang New Town, Liwan District, Guangzhou, elderly residents got off the convenient vaccination vehicle after receiving COVID-19 vaccine. Xinhua News Agency reporter Deng Hua photo

　　The reporter found in many places that the enthusiasm of the elderly for vaccination has improved significantly recently, but some elderly people are still worried about the safety of vaccines. Many elderly people admitted to reporters that they were mainly worried that "they are old and have basic diseases, which will bring adverse reactions after vaccination".

　　"Chronic diseases such as diabetes and hypertension are not absolute taboos for vaccination in Covid-19. As long as these chronic diseases are well controlled and in a stable period, Covid-19 vaccine can be vaccinated." Zheng Zhongwei, director of the Science and Technology Development Center of the National Health and Wellness Commission and head of the working group of the vaccine research and development special class of the the State Council Joint Prevention and Control Mechanism, said.

　　According to the situation of vaccine research and development and the practice of vaccination, the joint prevention and control mechanism of the State Council has defined the vaccination taboos of the elderly in the Work Plan for Strengthening Covid-19 Vaccination for the Elderly, including four types of situations in which vaccination cannot be carried out or postponed. At the same time, local health departments should implement the "four haves" requirement that vaccination units should have emergency personnel stationed in general hospitals with level 2 or above, emergency equipment and medicines, 120 ambulances on duty, and green channels for treatment in general hospitals with level 2 or above to ensure vaccination safety.

　　Step by step to carry out training on judging vaccination contraindications, and guide medical staff to scientifically judge vaccination contraindications; Well-known doctors from various specialties were transferred to form a vaccination consultation expert group to patiently answer various consultation questions … … Many places are refining the work of answering questions and doubts to eliminate the doubts of vaccination for the elderly to the greatest extent.

　　How convenient is it — — The "last 100 meters" is constantly getting through.

　　Every Tuesday and Saturday afternoon, it is the day when the "Medical Qingqi Team" comes to the door for vaccination in Pingguoyuan Street, Shijingshan District, Beijing. The "Medical Qingqi Team" consists of 5 to 6 street, community workers and medical staff, and is divided into two groups, each group can enter about 12 households.

　　"Conduct a health assessment first, ask the elderly whether they have basic diseases, look at past medical history, etc., and confirm whether the elderly are suitable for vaccination." Luo Yan, one of the medical staff of the "Medical Qingqi Team" and the medical department of Beijing Rehabilitation Hospital affiliated to Capital Medical University, said, "After the assessment, we will further communicate with our family members, and after the family members agree, they will sign an informed consent form and vaccinate."

　　Similar situations have appeared in many places recently. A special session of Covid-19 vaccination was held in Jinbi Yayuan Community, Baiyun District, Guangzhou. 63-year-old Ms. Liu suffers from rheumatoid arthritis. The medical staff inquired about her physical indicators in detail. After assessing that she met the vaccination requirements, she was instructed to take the third shot of vaccine.

　　On December 10th, He Lingling (left), a nurse from Fangmiao Street Community Health Service Center, vaccinated the elderly in the community with COVID-19 vaccine at COVID-19 vaccination site in Yaohai District, Hefei. Xinhua News Agency reporter Guo Chenshe

　　Li Zizhen, director of the immunization room of the Community Health Service Center of Dongcheng Sub-district Office in jieshou city, Anhui Province, told the reporter that twenty or thirty elderly people have come to get Covid-19 vaccine every day recently, and the telephone number for consultation is also from morning till night. A mobile door-to-door vaccination service team was set up in the local area, equipped with first-aid equipment and medicines, and came to the door at any time.

　　Set up green channels for the elderly, temporary inoculation points and mobile inoculation vehicles; Medical staff with rich experience in diagnosis, treatment and vaccination are selected to form vaccination teams, carrying common equipment and medicines needed during post-vaccination observation, and providing home vaccination services for disabled and semi-disabled elderly people … … Many places are optimizing various convenience measures as required, and getting through the "last 100 meters" for the elderly.

　　For the country’s 267 million elderly people over the age of 60, every 1 percentage point increase in vaccination rate means that more than 2 million people have built a barrier against serious illness and death. "The Spring Festival is coming, and now vaccination usually takes half a month to be effective, which is of great benefit to prevent large-scale spread when people go home and a large number of people migrate during the Spring Festival in Spring Festival travel rush." Zhong Nanshan said.

　　On October 27th, 2016, the inaugural meeting of Electrical Technology Branch of China Automotive Engineering Society was held in Shanghai Automobile Exhibition Center. The conference was presided over by Ning Xiaoyang, senior consultant of China Auto Parts Industry Company and chairman of China Auto Parts Electronic and Electrical Development Center.

　　In April 2022, General Secretary of the Supreme Leader visited Hainan and came to the "brain" of Nanfan Scientific and Research Breeding Base — — Sanya yazhouwan seed laboratory. The general secretary said: "Only by grasping the seeds of China with your own hands can you stabilize China’s rice bowl and achieve food security."

　　Nanfan, a large number of agricultural workers’ repeated migration journey. From September every year to May the following year, they come to Hainan from all over the world to take advantage of the unique tropical climate conditions here to carry out a series of scientific research activities such as crop seed breeding, hence the name "Southern Breeding".

　　At the moment, it is the season of the south. Let’s follow a rice seed to observe how it will grow from creating materials to breeding and seed production.

　　Sampling — — Sanya, Hainan

　　It took 10 years to produce a good variety.

　　Some have just been sown or seedlings, some are heading green, and some are golden to be harvested — — Walking into the Nanfan Base in Sanya, Zhongzhong Group, you can get a glimpse of rice at all growth stages.

　　"The advantage of Hainan is that there are abundant light and temperature resources, and we will sow here every one or two months." Shi Yitao, assistant of rice breeding in Zhongzhong Group, is a good way in the crop field. "Farmers will, we will;" Farmers won’t, and we understand. "

　　For a year, he guarded the experimental field like a child, and his broad face was tanned. "Water carefully every day to observe, prevent snails, birds and mice. I want every seedling to sprout and thrive. " Shi Yitao said.

　　It’s windy, rainy and sunny, which is a summary of the local climate by Nanfan people.

　　Sowing in the hot sun, sometimes, you have to hide from the rain four or five times for half a day. Whenever it rains, Shi Yitao is on tenterhooks: when the seedlings were young, he was afraid of the heavy rain and washed up the nutrient soil and washed away the seedlings; The rice is a little longer, catching up with the typhoon. The water in the field is more than 60 centimeters, leaving an ear on the water surface. It is raining against the wind and drowning again and again. "Danger is not afraid, and nothing is important to keep the seedlings."

　　In the corner of the experimental field, the iron fence was deeply embedded in the soil, and a small rice field was specially taken care of. "Specially rat-proof, afraid of gnawing materials." Shi Yitao gently pulled open the iron door and walked through a ridge, and the green and tall seedlings came into view.

　　"these are breeding materials R1607 with low cadmium gene introduced, which is already in tillering stage." Shi Yitao bowed down and took off a piece of leaf with tweezers, about 1 cm long, and carefully put it in a deep hole plate. "I hope it will be successful in one sampling."

　　From the summer of 2021 to now, this batch of materials has been planted in Hainan for three consecutive seasons, plus one season in Hainan in winter of 2020 and one season in Hubei in early 2021. It has been crossing, backcrossing and selfing for more than two years, and it has been five generations. Preliminary laboratory data show that the genetic traits of low cadmium gene have already appeared in future generations.

　　"If there is no problem with the re-inspection data, after maturity, you can select a trial plant with the best growth and the best laboratory genetic data from these 2000 strains." Shi Yitao said.

　　Just pick one plant, will it be too few?

　　"You don’t look down upon it, the seed setting rate is very high, one plant also has one or two thousand grains, and the ear of rice is half an arm long. This is also the reason why the rice variety Youyou 607 is favored by the market. "

　　"If you compare Quanyou 607 to an excellent ‘ Baby ’ Then R1607 is like an excellent ‘ Father ’ 。” Zhou Hua, director of rice testing of Zhongzhong Group, said that R1607 not only aggregated 8 rice blast resistance genes and 3 lodging resistance genes, but also aggregated 17 genes of sheath blight resistance, cold tolerance, flood tolerance, nitrogen efficiency and yield. Now, after introducing the low cadmium gene, even if rice is planted in fields with excessive cadmium content, it is low in adsorption or insensitive to cadmium.

　　How long does it take to breed a fine variety like Quanyou 607?

　　"It took 10 years from breeding to variety approval!" Zheng Ruifeng, the head of the R&D team of Quanyou 607 and the director of rice breeding of Zhongzhong Group, said that the creation of new materials is very uncertain. "There have been 52 cross combinations, and finally only R1607 was bred."

　　The R&D team will then introduce genes against bacterial blight, rice planthopper and fragrance, etc., and constantly upgrade and transform R1607 to become an all-around champion, so that the "baby" born will be better.

　　What is the most difficult thing in breeding?

　　Zheng Ruifeng replied in this way: if the varieties that show "leverage" are planted in other places for trial planting, some unexpected situations may occur, such as not resisting high temperature, low temperature, lodging, a certain disease, or a certain climate. Sensitive, "this will make all previous efforts and investments zero."

　　The early research and development is difficult, but the heart is still not hanging. Once it enters large-scale production, the strings in the heart will be tightly stretched. The bigger the promotion area, the more worried it is. "If farmers fail to harvest food, we will have trouble sleeping, and we will be relieved when we harvest it." Zheng Ruifeng said.

　　Detection — — Wuhan, Hubei

　　Breeding experts wear "gene glasses"

　　In Wuhan, Hubei Province, the genotyping laboratory of the Life Science and Technology Center of China Seed Group, the low cadmium sample sent from Sanya base, finally ushered in the key experimental link — — DNA genetic material was extracted and analyzed.

　　Zhang Xiaobo, the head of the laboratory, tapped the button, and the shaker, centrifuge and PCR instrument ran one after another. The data showed that the recovery rate of differential loci was 88.7%, and the recovery rate of whole genome reached 97.5%.

　　What do these data mean? "This shows that the low cadmium gene has indeed been stably passed on to the offspring of R1607. After the upgraded version of R1607 matures, a new trial production process can be started." Zhang Xiaobo explained.

　　"In the breeding process, the laboratory and the experimental field are closely linked." Ye Rongjian, deputy director of the Technology Platform Department of the Science and Technology Center of Zhongzhong Group, said that the genetic performance after the introduction of low cadmium gene is difficult to observe by experience. "Is cadmium adsorbed into rice seeds? The naked eye can’t see it at all."

　　"When R1607 was first created, molecular biological breeding technology was just beginning, and we took the path of traditional cross breeding combined with molecular breeding assisted selection. Nowadays, molecular marker detection and genome breeding technology have become very common, which is like wearing a pair of glasses that can see through the function of genes for breeding experts. " Zheng Ruifeng said that intelligent breeding in the future, relying on artificial intelligence, big data and biotechnology, will be more efficient and accurate.

　　Of course, the powerful function of this pair of glasses depends on the breakthrough of basic research. "The reason why the introduction of low cadmium gene has achieved results for more than two years is because the functional sequence of low cadmium gene is very clear." According to Ye Rongjian, there are about 50,000 genes predicted in rice. At present, about 4,000 genes are cloned and their functions are clear. It may take many years for a gene to know its functions, and the road ahead is still very long.

　　"The laboratory not only undertakes the task of detection and analysis, but also explores the mystery of genes." Nie Dongming, the seed administrator, pushed open the heavy security door, and a germplasm resource bank with more than 100,000 rice materials was presented. Here, at the temperature of 4 degrees Celsius, the seeds enter a dormant state and can be safely stored for 5-mdash; Ten years.

　　Zhou Hua said that the germplasm resource bank is a treasure house for creating breeding materials. At that time, Academician Yuan Longping discovered the special material of wild rice sterile plant "Wild Abortion" in Sanya, and achieved the breakthrough of hybrid rice breeding.

　　R1607′ s breakthrough in rice blast resistance is also due to the germplasm resource bank. "At that time, we were making a breakthrough in the technology against rice blast. I heard that the Chinese Academy of Sciences discovered a gene with strong resistance, but breeding experts did not have this material at hand. We went to the germplasm resource library to search and found the original material. " Zheng Ruifeng introduced that this peasant variety was used to cross and backcross with indica rice varieties, and a series of materials containing rice blast resistance genes were bred.

　　"If things in nature are lost, you may not find them when you want to use them in the future. The importance of the germplasm resource bank is now more and more deeply understood. " Zheng Ruifeng said that it is a source protection when its value is not clear and the advantages of germplasm resources are not tapped.

　　Zhou Hua introduced that China Seed Group and Yazhouwan Seed Laboratory jointly issued a list for the first-class scientific research institutes and universities in China, and Industry-University-Research jointly integrated gene resources, and there were more than 10 topics in the field of rice alone. In addition to further cooperative research on low cadmium genes, there are also cooperation in herbicide resistance and rice false smut resistance. "The goal is to make excellent rice varieties full of treasures."

　　Seed production — — Hainan dongfang

　　One mu of seed production can be used for more than 100 mu of fields.

　　"Yanmei, throw me the seedling!" "Good, then!" Fu Yanmei didn’t lift her head. A bunch of tender rice seedlings came out and flew over eight or nine women who worked hard, drawing an arc over the paddy field and accurately "delivering" it to Zeng Yabei.

　　On February 3rd, gancheng town, Dongfang City, Hainan Province, after the Spring Festival, seed production and rice transplanting have been busy for more than a week. The villagers cooperated skillfully, transplanting rice in the field, and there were bursts of laughter from time to time.

　　Such busy and cheerful scenes often appear in the process of seed production. In the whole seed production process, the most attractive thing is heading and flowering, which is also called catching powder.

　　At the end of October last year, in this field, the reporter witnessed a scene of catching powder. The sky clears up, the temperature rises, the male parent and female parent materials in the rice field bloom and spit, and pale yellow flowers are dotted with light green ears of rice swaying gently in the breeze. A 40-meter-long rope hangs in an arc on the ear of rice. The two workers each held one end and walked quickly forward in parallel. Where the rope passed, the ears of rice touched, the stamens trembled, the pollen floated to the pistil of the female parent, and suddenly a pale yellow powder fog was stirred in the field.

　　Wang Shiming, general manager of Hainan Nongle Nanfan Technology Co., Ltd. said: "Breeding is to bring a bag of seeds and carry a bag of seeds back. Seed production is different. One acre of seed production can be used for more than 100 acres of fields. "

　　There are many seed production processes, so it is necessary to plant seeds in reverse order to let parents meet this flowering period. For example, it takes 100 days for the male parent of Quanyou 607 to plant and 80 days for the female parent, so the male parent should plant 20 days in advance; After that, we constantly observe the leaf period, analyze the flowering period, and sometimes adjust it through water and fertilizer to ensure that the flowering period meets.

　　"Artificial powder driving can improve the seed setting rate of hybrid rice." Wang Shiming introduced that many years ago, there were as many as 100,000 people in Hainan from Pingxiang City, Jiangxi Province. In recent years, the country has revitalized the seed industry, and Pingxiang has also introduced measures such as subsidies for large seed producers and subsidies for grain production. Encouraged by this, many Jiangxi farmers who have produced seeds in Hainan have returned to their hometowns for development.

　　"Raising seedlings, transplanting seedlings, heading and pollination, harvesting and drying seeds, selecting seeds and packaging, I can play when I am young." Wang Shiming has been following his parents to Hainan for more than 20 years. His skin is tanned and he speaks slowly. In 2022, Dongfang City, where he lives, was recognized as a national seed production county, with a million mu of fertile land in Thanksgiving Plain. "Winter seed production starts at the end of December every year, and the seeds are harvested in April and May of the following year, which is just the time for the middle and lower reaches of the Yangtze River."

　　Affected by rising land rent and labor costs, Hainan rice seed production has been moving westward, from Sanya to Ledong Li Autonomous County, and then to Dongfang City. "The average annual land circulation per mu in the East is 1,300 yuan, but it has already exceeded 3,500 yuan in Sanya." Wang Shiming said.

　　In the middle and late September of 2022, Wen Mincao, deputy manager of the production department of Zhongzhong Agricultural Science and Technology Company, received an urgent task. When the seed production area of Quanyou 607 Hainan suddenly increased from the original six or seven thousand mu to more than 20,000 mu, his head was buzzing. Where can he find the producer and production base?

　　The Chinese company implements the order system and gives plans to manufacturers and professional teams all over the country every year. However, the farming season in the mainland has passed in winter and it is difficult to produce seeds; Although Hainan can produce seeds, it is also the winter melon and vegetable season, with less open space, high land rent and early seed delivery time. At one time, it is a bit intense to "grab the base".

　　Thanks to Wang Shiming’s contacts in many ways, Wenmin Cao took only one week to reach an intention on 6,000 mu of land and finally breathed a sigh of relief. "Seed production counties support the integration of production, processing, warehousing, packaging and logistics. With favorable policies, we have signed a cooperation framework for the integration of production and supply chain with local manufacturers, which can be produced locally, packaged locally and sent to the market, and can be stored locally if they are not sold out."

　　All the efforts are worthwhile.

　　In the middle and lower reaches of the Yangtze River, farmers who have tasted the sweetness have long been thinking about good seeds. In Shilou Village, Wudian Town, Zaoyang City, Hubei Province, Chen Bangguo, a large grain grower, called Qiu Yunze, a seed dealer in Wudian Town, after planting winter wheat.

　　"Good seeds are in demand! When we tried to plant Quanyou 607, it was Laoqiu who came to sell it, and he guaranteed it, saying that it was not good to compensate my output. As a result, two or three hundred kilograms of rice were added to an acre of land. I am happy to invite Laoqiu to eat! " Chen Bangguo said.

　　"In the early stage, we will build a model field display, and invite large households to go to the scene to observe the harvest and yield measurement, so that more farmers can see the comparative advantages of varieties. In the later stage, collect information about high-yield farmers, make posters, and organize seedling meetings from seedling stage to heading stage to expand influence. " Speaking of the promotion experience of good seeds, Wang Hanyong, deputy sales manager of Hubei Branch of China National Seed Group, talked endlessly.

　　The field of hope, season after season, the story of a fine variety will be told constantly.

　　Planning for this issue: Yin Xinyu, Wu Yan and Cheng Juxin

Original title: The anti-epidemic documentary film Days and Nights in Wuhan shocked the audience by showing the heroic city war epidemic story in Han Dynasty.

Record life with life, and create a heroic hymn of ordinary people. The first domestic anti-epidemic documentary film co-produced by the Propaganda Department of Hubei Provincial Party Committee, Film Channel and Hubei Radio and Television Station held a special screening ceremony for Hubei media at Kaide 1818 Lumiere Cinema in Wuchang on the afternoon of 16th. During the epidemic in COVID-19 at the beginning of last year, the photojournalist of Changjiang Daily was always on the front line of anti-epidemic, and his work was selected as the material for the anti-epidemic documentary film Days and Nights in Wuhan. More than a dozen Hubei media reporters, representatives of some hospitals and communities in Wuhan, and some filming teams that provided materials for Days and Nights in Wuhan watched the film.

Not a voice-over, not a line.

Sun Tzu recited Tang poems to cheer up his grandfather in the intensive care unit; The husband cried in front of the camera, saying that his wife wanted to live and made delicious food and sent it to the hospital. Medical couples in Jinyintan Hospital spend the night in the car outside the hospital to avoid infecting their families … …

There is no popular actor and no designed acting skills. Every character and story in Days and Nights in Wuhan comes from the real record at the peak of Wuhan epidemic last year. The film was shot by more than 30 photographers in several hospitals, and many shots went deep into the intensive care unit. The audience could see scenes that they could not see at ordinary times: medical staff feeding patients, changing medicine, turning over and scrubbing their bodies, including surgery and rescue.

The camera was also aimed at the patients’ families and volunteers outside the hospital. They also fought to win time for the patients’ recovery and the smooth delivery of pregnant women. These pictures have no processing or rendering, and truly show the real picture of people fighting the epidemic in a city.

The most touching picture in the film is that just after a patient was sent away, a little life came into this world crying. This is the alternation of death and life, which is the continuation of life hope. The birth of a little life also smeared a bunch of bright colors for the world.

Dozens of times in the film, the images of Wuhan city were inserted, from the initial dark clouds, to the bright lights in the three towns during the joint fight against the epidemic, to the turning of Wuhan into safety when cherry blossoms were in full bloom. Raindrops from the Yellow Crane Tower, lonely cyclists on the Yangtze River Bridge, birds on the branches of hospitals, and the streets and alleys in Wuhan seemed to all talk, telling that our city was in a critical moment, we were United as one, we were fighting, and we would surely defeat the virus.

More than 1000 hours of precious materials, 30 first-line photographers of war and epidemic, recorded their lives with their lives, and created heroic hymns of ordinary people. The film didn’t use a voice-over or write a line. Everything is extremely real, and it conveys more love and warmth, which is to cherish our hard-won happy life now.

"Delicate restraint, gentle telling", "plain with the power to hit people’s hearts", "the lens language is full of beauty" and "the real record is better than the top performance" … … Many people expressed such admiration after watching it.

The medical staff looked down with tears all the time.

"The whole process was seen with tears. The camera language brought me to that moment last year, when my colleagues and I joined hands to die. Seeing the medical staff in the movie, I also saw my colleagues and I were there. "

After the screening, Chen Sheng, a doctor’s representative from Wuhan No.7 Hospital, said that the most impressive scene was the baby’s first cry in the morning, which suddenly pulled his heart up. At that time, his tears could not stop flowing downwards, because it represented new life and hope.

Chen Sheng’s colleague, Dr. Chen Huifang, said that she also watched it with tears in her eyes. This film brought her back to the difficult period of fighting the encounter. She saw the figure of her colleague and the story of the heroic Wuhan people. What moved her in particular was to see an old man in the film who remained optimistic, strong and humorous after more than ten days of treatment, and the scene of the birth of a newborn. The tenacity of life made her shed tears.

Yao Shanglong, the chief physician from Wuhan Union Medical College Hospital, is not only an anti-epidemic fighter, but also a person who recovered from COVID-19 infection. After watching Days and Nights in Wuhan, Yao Shanglong said with emotion that he spent more than 30 days and nights in the ward a year ago. He saw not only doctors but also patients. He experienced volunteers driving him home and community staff serving him, which fully demonstrated that Wuhan is a heroic city. This epidemic is ruthless, but there is love in the world, which fully embodies the spirit of great love of Wuhan people. It will be difficult for everyone in 2020, and everyone will be great.

What the film gives him is objective, real and touching, with life and death in it, but it gives people positive energy, the optimism of our medical staff and our patients, and the support of our family and all walks of life. During his stay in hospital, it was these that made Yao Shanglong finally overcome his illness.

The film Days and Nights in Wuhan uses a lot of video materials from Tan Haiyan’s team of Hubei Radio and Television Station. After watching the screening, Tan Haiyan and photographers Wu Qin and Wang Wei were interviewed. Tan Haiyan said that this is the fourth time she has watched a film. What is different this time is that she watched it in the cinema for the first time. The fourth time I saw her, I still shed tears. The scene that made her cry was that the film changed from the first act to the second act, which was the empty mirror of Wuhan city. It’s so beautiful. She knows that it’s not easy for all the heroes of Wuhan people to be behind this beauty. It’s only after 76 days of fighting that we got such a beautiful night scene. (Reporter: Wan Jianhui)

　　CCTV News:At present, the flu season has entered, and the level of flu activity has been on the rise recently. However, everyone has some misunderstandings about the flu. Let’s sort it out.

　　Myth 1: This year’s flu is more serious than in previous years.

　　Every winter and spring is the high incidence of influenza. According to the monitoring data released by China CDC, the overall activity level of influenza in China is lower than that in the same period of last year, and will show a downward trend from the end of this month.

　　Song Tie, Deputy Director of Guangdong CDC.: "It is mainly influenza A (H1N1) virus. There are many outbreaks in primary schools this year, but at present, with the school holidays, this outbreak will gradually decrease."

　　Myth 2: This year’s influenza virus variants are easy to cause complications.

　　In the past two days, many parents have been fidgeting because of the news that "the flu virus turned to attack children’s brains this year". Does this year’s influenza virus mutate, and is it easy to cause complications? China CDC said that at present, no variation of influenza virus has been found in various places.

　　Whether you will get complications after suffering from the flu depends on the patient’s own resistance and the power of the virus. Generally speaking, influenza may cause pneumonia, myocarditis, or central nervous system diseases including encephalitis. This is not a new situation this year, so there is no need for excessive panic. However, these five groups of people should pay special attention. They are more likely to get flu complications than ordinary people and belong to high-risk groups.

　　1. Children under 5 years old

　　2. Older people over 65 years old

　　3. Patients with chronic diseases and immune diseases

　　4. Obese people

　　5. Pregnant women

　　Myth 3: Strong people don’t have to be afraid of the flu.

　　Doctors said that people who are strong and have strong resistance should not think that their chances of getting the flu are low, so they don’t pay attention to rest and prevention, so that the virus also has the opportunity to take advantage of it, such as fatigue, hunger, or soaking clothes after sweating a lot. Among influenza complications, the incidence of myocarditis is higher in healthy young adults. This is because these people are more immune, and when they are invaded by the virus, their own defense system will also damage myocardial cells while removing the virus.

　　Myth 4: Influenza is treated as a common cold.

　　The doctor said that the symptoms of the common cold are mild, and most of them are respiratory symptoms such as sore throat, cough and stuffy nose, while the flu is accompanied by high fever above 38℃, chills, dizziness and headache, muscle aches, etc., and it is highly contagious. Once you have cold symptoms, you should go to the hospital for examination and diagnosis, and prescribe the right medicine. At present, antiviral drugs for influenza are prescription drugs, which must be taken under the guidance of a doctor. Antibiotics have no effect on influenza.

　　Myth 5: relying on "remedies" such as vinegar fumigation to prevent influenza

　　In order to prevent the flu, some people smoke vinegar at home. The doctor said that acetic acid can only kill bacteria when it reaches a certain concentration. Moreover, the flu virus is not a bacterium, and it cannot be killed by acetic acid at all. Blind vinegar fumigation will also aggravate the condition of patients with bronchitis and emphysema.

　　Others rely on oral vitamin C to prevent influenza. Doctors say that taking enough fruits and vegetables has the same effect as oral vitamin C, which can improve immunity, but it has no antiviral effect. According to the method of drinking Radix Isatidis and other traditional Chinese medicines to prevent influenza, the doctor said that Radix Isatidis is cool and not beneficial to all patients.

　　Yang Shuyu, President of Xiamen Medical Association, Fujian: "When a cold is prevalent, it is very important to pay attention to improving your immunity, instead of blindly taking drugs, which will affect and damage your immunity."

During the Spring Festival, for pet owners who have travel plans, "staying behind" pets has become a big problem.

During the Spring Festival, the orders of pet foster care institutions around the country increased greatly, and there was a situation that "one cage is hard to find", and the price also rose. Some foster care institutions launched SVIP rooms as high as 1299 yuan/day, and the price was comparable to that of five-star hotels. In addition to pet foster care, "door-to-door feeding" is also a more cost-effective choice for pet owners. During the Spring Festival, the lowest price for door-to-door feeding of pet cats in Beijing is in 100 yuan/time, which is about 25 yuan’s holiday fare increase compared with the usual door-to-door feeding price.

For businesses, it is natural not to miss this good opportunity to make money. Pet foster care service is becoming a hot business. Before this year’s Spring Festival, Box Horse launched services such as on-site pet feeding and dog walking in Shanghai during the Spring Festival. The original price was 128 yuan, and the snapping price was 98 yuan.

Home feeding is more cost-effective

During the Spring Festival, many pet shops received a large number of foster care orders. The demand for pet foster care in Shanghai pet foster care shop this Spring Festival has increased by about 30% compared with last year. In October 2023, customers in Beijing pet foster care shop began to book rooms during the Spring Festival, and in December 2023, pet foster care rooms were fully booked. The owner of pet foster care in Guangzhou said that he would receive more than a thousand foster care orders during the Spring Festival. It is found that in some pet shops in Beijing, the Spring Festival foster care service should be reserved 15 -60 days in advance, which can be described as "a nest is hard to find".

The strong demand has also pushed up the price of pet foster care. Some pet owners said that the cost of pet foster care for 8 days during the Spring Festival has even been equal to the rent of apartment rooms in Beijing. The data of several pet foster care shops in Beijing were selected, and it was found that most pet shops have introduced rooms with different stalls, and basically every foster pet shop is equipped with a camera for pet owners to check the situation in real time. In addition, cleaning and disinfection are also standard in pet shops. In some rooms with higher fees, its supporting services will also increase services such as massage, accompanying play, free shuttle and bathing in the sun.

In some pet shops for cats, the price of some ordinary rooms is 100-200 yuan/day, and the daily price of luxury rooms is as high as 500 yuan. The difference between "deluxe room" and "ordinary room" lies in the size of the room, the number of cats accommodated and the supporting services. The price of "Sunshine Suite" in a pet shop in Sanlitun, Beijing is 899 yuan/day, and the daily price of "SVIP Room" in a pet shop in Baiziwan, Beijing is 1000 yuan/day, and the daily foster care price exceeds that of five-star hotels.

In addition, the price of foster dogs is higher than that of cats. In the pet shop in Sanlitun, Beijing, the price of the same type of room type foster dog is 100-300 yuan/day more expensive than that of the cat. If the foster care is calculated as 8 days during the Spring Festival, at least 800 yuan is needed, which is equivalent to the cat’s living expenses for nearly two months. If you want pets to receive better services, the total cost of foster care can reach 10392 yuan.

It is worth noting that in addition to foster cats and dogs, some pet shops offer foster rabbits and birds, and the daily price is below 100 yuan.

In addition to pet foster care, door-to-door feeding of pets is gradually becoming popular. Before the Spring Festival, there will be advertisements for door-to-door feeding services on social platforms, community corridors, elevators and other places. Most of these people who provide feeding services are private, and such people will label themselves as professionals such as "senior pet owners and pet store clerks". Door-to-door feeding services include food cleaning, adding food and water, shoveling excrement and adding sand, interactive play, health monitoring and so on. The charging standard varies according to the distance, the number of pets and holidays.

According to the titanium media and titanium map, the service price of door-to-door cat feeding in Beijing includes five aspects: cat feeding service fee, basic door-to-door fee, fare increase per kilometer, fare increase for multiple cats and fare increase on holidays. Among them, the prices of more than half of the "pet caregivers" are between 31 yuan and 40 yuan, and the average prices are 35.9 yuan/time and 37.7 yuan/time respectively; The average price of fare increase for "pet tutors" whose door-to-door distance exceeds 1km is 6.6 yuan/time, and the average price of fare increase for feeding one more cat is 7.4 yuan/time.

On holidays, almost all "pet caregivers" will increase their prices, with the range of 11-30 yuan/time accounting for over 70%, and the average price is 25.7 yuan. According to the lowest price during the Spring Festival, the daily price of feeding a cat at home is 99.3 yuan/day. Door-to-door feeding service can be selected once every 2-3 days, and the total cost during the Spring Festival is about 200-300 yuan, which is more cost-effective and cost-effective than pet foster care shops that have to pay every day.

Pet foster care business continues to heat up

There are more than 30,000 related enterprises registered in China.

The data shows that in 2023, the number of pet dogs in China was 51.75 million, an increase of 1.1% over 2022; The number of pet cats is 69.8 million, an increase of 6.8% compared with 2022; The consumption market of urban pets (dogs and cats) is 279.3 billion yuan, an increase of 3.2% compared with 2022. In the pet consumption market of more than 200 billion yuan, more and more pet supporting services are applied. The pet business is said to be a gold-sucking business for enterprises, and more and more brands are eyeing the pet service.

Before the Spring Festival this year, Box Horse APP launched the Spring Festival pet door-to-door feeding and dog walking service in Shanghai. Professional pet companions have more than one year’s experience in raising pets independently, and broadcast live video of the whole process to the owner.

It is reported that the service can only be used during the Spring Festival, and the date can be from the 27th of the twelfth lunar month to the 7th day of the first lunar month. The main contents of the service are changing water and feeding food at home, walking the dog and playing with you. This service was completed by the cooperation of Box Horse and unigo, a pet service brand. The company was established in June 2022, and mainly engaged in pet bathing, pet grooming, dog walking and door-to-door feeding services.

At present, there are more than 30,000 enterprises in China whose enterprise names, business scope or products and services include "pet foster care", and most of these enterprises were established between 2016 and 2020. Among them, in 2016, the registered growth rate of "pet foster care" related enterprises was the fastest, reaching 96.8%; In 2019, the number of registered enterprises related to "pet foster care" was the largest, reaching 7880. In terms of geographical distribution, Shanghai has the largest number of "pet foster care" related enterprises, reaching 3898; In addition, the number of "pet foster care" related enterprises in Guangdong Province and Jiangsu Province also exceeds 2,000.

Whether foster care or door-to-door feeding, there are certain security risks. In pet foster care, it is difficult to guarantee the sanitation of foster care environment, and pet shop staff are not well cared for. In the aspect of door-to-door feeding, it is not uncommon that the property of the pet owner is lost and the door-to-door feeding personnel are bitten by pets during feeding. At present, the pet foster care industry is still in an "extensive" state, and there is no unified service standard for pet foster care in the industry. In the future, the pet industry still needs to be further standardized to reduce security risks, so that this service can develop more sustainably.

In fact, the styling and interior of BYD Han has not changed at all in the 2022 model, and it is still a strong coupe style, and it is also full of BYD-style luxury and sense of technology. In addition to the technology-assisted configuration of armed teeth and the optional 15.6-inch large screen, BYD Han’s materials and color texture collocation can also be called the top name-this is a car that will be amazing at first sight, but after watching it more, you will feel that many design elements still come from it. And it appears on the streets of first-tier cities, and it doesn’t feel against it.

The core of the 2022 BYD Han can be said to have been upgraded in a comparable way, from the old DM system with 2.0T+ motor to DM-i and DM-p based on 1.5T engine. Compared with the previous generation DM, the fuel engine in the new powertrain is upgraded to hybrid exclusive 1.5T, which is more suitable for hybrid working conditions in calibration. At the same time, the cruising range of both DM-i and DM-p models is greatly improved. The whole system started with a pure electric cruising range of 121 kilometers. The DM-i flagship with a pre-sale price of 292,800 yuan has a pure electric cruising range of 242 kilometers, while the DM-p four-wheel drive flagship with the highest pre-sale price has a cruising range of 202 kilometers.

This kind of cruising range performance is actually to make up and greatly improve the short board that the old Han DM can only run short-distance local routes by pure electricity. When traveling long distances, the old DM is not really too fuel-efficient if it takes the high speed. After all, the pure electric cruising range of the previous generation DM with tens of kilometers plus self-charging SOC can only reach 70%. In long-distance travel, the battery combined motor becomes a burden. The updated hybrid system, used in daily cities, may not need engine intervention at all, and it is replaced by battery+motor pulling the engine to run.

To some extent, BYD Han has opened the "success password" of domestic high-end cars, because its pricing has not been regarded as "crazy", but has been widely accepted by the market, that is, people will really buy it. You know, at a price of about 300,000 yuan, you can already buy a high-end version of the joint venture brand B-class car, such as the Accord, Camry and Teana, and other traditional home and business cars. However, this is a domestic car, and although it still has some minor faults, it seems that it has begun to leave some joint venture cars behind, which is the embodiment of the product, and of course, it benefits from the green brand policy.
