The flu is not an ordinary cold! The whole country has entered the flu season and taught you how to prevent the flu!

On December 19th, 2024, China Center for Disease Control and Prevention released the China Influenza Surveillance Weekly, No.835 (December 9th-15th) in the 50th week of 2024. According to the test data, the positive rate of influenza detection in southern and northern provinces continues to rise, mainly with subtype A(H1N1)pdm09.

1. Can you tell the difference between influenza, influenza A and influenza B?

Influenza, referred to as "influenza" for short, is divided into four types: A, B, C and D. It is an acute respiratory infectious disease caused by influenza virus, which can cause outbreaks and epidemics worldwide.

Second, how is the flu infected?

It is mainly spread by droplets such as sneezing and coughing, and directly or indirectly contacts infection through mucous membranes such as mouth, nose and eyes. Contact with items contaminated by viruses can also be infected through the above channels.

In certain places, such as crowded, closed or poorly ventilated rooms, it may also spread by aerosol.

3. Who are the susceptible populations of influenza?

The incidence of influenza is high, and the whole population is generally susceptible. Some high-risk groups, such as the elderly, infants, obese people, pregnant women and patients with chronic diseases, have a relatively high risk of serious complications caused by influenza virus infection.

4. What’s the difference between flu and common cold?

Mild flu is often similar to the common cold, but fever and systemic symptoms are more obvious.

Common cold. Sneezing, stuffy nose, runny nose and cough are the main symptoms.

Flu Generally, the acute onset is mainly high fever, and the body temperature is mostly 39-40℃. Patients often have systemic symptoms such as chills, chills, headache, muscle and joint pain, fatigue, loss of appetite, and respiratory symptoms such as nasal congestion, runny nose, sore throat and cough. It can also cause gastrointestinal symptoms such as abdominal pain, abdominal distension, vomiting and diarrhea. In addition, there may be other symptoms such as chest pain when coughing, facial flushing and conjunctival congestion.

5. What are the treatments for influenza?

High-risk groups infected with influenza virus are easy to cause severe influenza, and antiviral treatment within 48 hours of onset can reduce complications, mortality and hospitalization time.

6. Influenza ≠ Three great tricks of common cold, scientific prevention

Step 1 get the flu vaccine

Vaccination against influenza is the most effective means to prevent influenza and reduce influenza-related severe illness and death. It can significantly reduce the risk of influenza and serious complications of vaccinators.

2. Drug prevention

3. Personal protection

(1) Wash your hands frequently. Wash your hands frequently and pay attention to washing your hands correctly. Do not touch your eyes, nose or mouth with dirty hands.

(2) cover your mouth and nose. When coughing or sneezing, cover your mouth and nose completely with paper towels or elbows, throw the used paper towels into the trash can in time, and wash your hands in time.

(3) less gathering. During the influenza epidemic season, the elderly, children, pregnant women, patients with chronic basic diseases and other high-risk groups should try their best to reduce going to crowded places and closed spaces, and wear masks if necessary. Advocate the public to wear masks in public transport, closed spaces and crowded places.

(4) Regular ventilation. Open the window for ventilation at least three times a day for at least half an hour each time to keep the indoor air fresh.

(5) Enhance immunity. Enhance physical fitness and dietary balance. Maintain a scientific diet and daily life, actively exercise and improve the body’s immunity.

Recently, Ms. Yang in Shanghai found that many people around her had the flu. In order to take preventive measures and worry about the elderly and children, she took her 70-year-old mother and her 6-year-old daughter and was vaccinated with tetravalent influenza virus split vaccine. This vaccine is independently developed by Shanghai and can be used by people of all ages. Ms. Yang thinks that it will be more reassuring for a family to get the same vaccine.　

01, tetravalent influenza virus split vaccine

Influenza virus can cause seasonal epidemic every year because of its changeable virus antigen and rapid spread. At present, influenza vaccination is an effective means to prevent influenza and related severe illness and death.

The World Health Organization (WHO) has recently released the influenza strains in the influenza epidemic season of 2023-2024 for medical institutions’ reference, and the newly listed tetravalent influenza virus split vaccine of China Institute of Biological Products was developed by using the influenza strains recommended by WHO in the influenza epidemic season of 2023-2024.　

02. What are its advantages?

Contains more virus types

Trivalent influenza vaccine includes three virus types: H1N1 (A), H3N2 and Victoria strain B, while tetravalent vaccine also includes Yamagata strain B..

Universal for all ages

The first domestic universal tetravalent influenza virus split vaccine independently developed by Shanghai was approved by National Medical Products Administration on November 22, 2022, which achieved the unification of vaccination dosage forms for infants, adolescents, adults and the elderly for the first time in China and became the first exclusive universal tetravalent influenza vaccine for all ages in China.

Safer and more efficient

Shanghai Institute of Biological Products took the lead in completing the clinical study of full-dose tetravalent influenza vaccination for infants aged 6-35 months in China. The results showed that after two doses of tetravalent influenza vaccine from Shanghai Institute of Biological Products were inoculated, the highest serum protection rate against four subtypes of influenza was 98.6%, and the serum antibody protection rate, antibody seroconversion rate and geometric average titer of antibody were significantly higher than half dose, and there was no statistical difference in the incidence of overall adverse reactions.

Adverse reactions are lower.

The tetravalent influenza virus split vaccine of China Institute of Biological Products adopts two-step centrifugal refining and purification process, and contains no preservatives and antibiotics, thus minimizing the risk of adverse reactions.

Xiaoyun specially reminds everyone that in order to protect the health of the whole family, please ventilate, wash your hands and clean frequently. These simple and important preventive measures can effectively curb the spread of diseases and keep us away from germs.

The final chapter of the trilogy of life! Viva La Vida is warm and healing.

Special feature of 1905 film network Directed and starring, the film will be released nationwide on February 10th, the first day of the Lunar New Year. The film tells the story of "mindless" Lu Tu and "unhappy" Ling Min, two seriously ill young people with different personalities. Because of the agreement of "relay for life", they mistakenly embarked on a healing story full of love and strength.

After 2015 and 2020, the "trilogy of life" directed by Han Yan ushered in the final chapter — — Viva La Vida filled many audiences with expectations. According to the statistics of the ticketing platform, as of February 2, the pre-sale box office of Viva La Vida has exceeded 10 million yuan, and the number of pre-sales people has exceeded 200,000.

"Xi" of love in the Spring Festival file

In the Spring Festival camp featuring "Four Happiness Coming", the movie "Viva La Vida", a tender and healed love, is somewhat unique, so what is worth seeing in this Spring Festival camp?

Su Qin, an emotional expert who has seen the film, gave her reasons. First of all, this film is very energetic. Although it tells the story of two seriously ill men and women, the spiritual core it expresses is refusing to lie flat and refuse internal friction. Secondly, the film was wrapped in a comedy coat, and there were laughter, tears and feelings during the movie. Finally, it can lead us to think and explore the meaning of life itself, which is also the connotation of the trilogy of life directed by Han Yan.

The bright and lively moments in the film bring joy to the face: staying with your lover, tasting steaming food, exploring strange scenery in the distance, and getting together with friends and family … … It is these wonderful bits and pieces that together constitute the vitality conveyed by the film.

Healing love through mutual redemption.

Viva La Vida, as the final work of the trilogy of life directed by Han Yan, continues the bright and cheerful tone of the previous work and the philosophical thinking and discussion on the topic of love and life, and keeps the camera focused on the sadness and joy of the fate of ordinary people.

The film focuses on the love story of "relay for life" between two critically ill patients. The actor and actress starring Peng Yuchang and Li Gengxi also make the audience full of expectations. They subvert the previous role images and interpret the healing love of two critically ill patients with real and moving acting skills.

In the movie, the relationship between Ling Min and Lu Tu is a kind of deep complementary love. Ling Min (played by Li Gengxi) has a typical "hedgehog type" personality, and her appearance is covered with hard thorns. In life, she can defend her rights in the face of injustice, quarrel, or go to the hospital for treatment alone, but her heart is soft and fragile. When she sees others deliberately bullying and making fun of Lu Tu, she will bravely stand up and help him.

And Lu Tu (Peng Yuchang) is like a "Transformers", disguising himself with a changeable shell. Compared with Ling Min, his heart is very firm. He will have his own things to protect and protect his family. But externally, he presents an image of laughing and laughing. All his expressions seem to be ungrounded, but this so-called ungrounded is to cover up his inner uncertainty about the future.

Therefore, these two people are deeply complementary in character, and they also redeem each other when they meet and get along. However, complementary love often goes through a long running-in period, so in the movie, Lu Tu and Ling Min are more like a pair of tell it to the judge. Emotional expert Su Qin also has his own interpretation of this. "This kind of love can also be attributed to a kind of" situational "love, that is, putting them both in a special situation where they are seriously ill, but often this kind of love is stronger than the love encountered in ordinary life."

Ling Min and Lu Tu live hard in every moment. Although their lives are in trouble at present, they still don’t give up, bravely and actively fight against their fate and are full of enthusiasm for the future. In the preview released, Lu Tu and Ling Min cheered with clenched fists and shouted "Come on Ollie" to life, conveying infinite hope and strength to the audience.

As the only warm realistic movie in the Spring Festival, "Viva La Vida" uses the brave "life and death agreement" of two young people to get rid of the haze of fate and see the sunshine of life. I look forward to meeting you in the cinema on the first day of the New Year’s Day and feeling the power of love and life together!

The 281st issue of ＂Criminal Investigation man of iron＂ concealed the illness and completed the transnational pursuit mission.

In the ward of the Department of Nephrology, Xu Hongsheng, who usually loves to talk and laugh, lies quietly in the hospital bed, looking tired and sleepy. What happened to this "criminal investigation man of iron" who was famous in Fujian Minqing police? This has to start from that day …

On that day, Xu Hongsheng, deputy head of the Criminal Investigation Brigade of Minqing County Public Security Bureau in Fujian Province, who had just returned from treatment in Shanghai, heard that Zhan, a fugitive from the "Red Wanted Order" of the Ministry of Public Security and suspected of fund-raising fraud, appeared in Malaysia. Because it is the first time in the history of public security in Minqing, there may be language communication barriers, which requires the appointment of a policeman with high comprehensive quality. The bureau leaders are worried about the candidate for this case. After understanding the situation, Xu Hongsheng volunteered to carry out this task. The leader was worried that his physical condition would be too much for him, but in the end Xu Hongsheng insisted and had to agree to go. In fact, in the eyes of bureau leaders, Xu Hongsheng, who has rich experience in handling cases, is the best candidate for this operation. After the approval of the leader, Xu Hongsheng immediately went to Malaysia to pursue the pursuit, but no one knew that at that time, he had made an appointment with the doctor to go to Shanghai for review, but it was temporarily cancelled because of the pursuit mission.

After Xu Hongsheng arrived in Malaysia, he did not care about the boat and the car, and immediately began to control the suspects. The sly suspect Zhan seems to smell something and has been closed for several days. In order not to alarm the snake, Xu Hongsheng stayed near Zhan’s possible hiding place for three days and three nights. When he was hungry, he ate bread with mineral water, and the clothes wet by the dew in the morning could not be changed. Finally, the suspect Zhan couldn’t hold back and was successfully captured by Xu Hongsheng as soon as he went out. After Xu Hongsheng escorted Zhan back to Fuzhou, he didn’t take a break and devoted himself to the intense pre-trial work.

During the trial, colleagues found that Xu Hongsheng was holding his head in his hands, his face was white, and the beads of sweat on his forehead kept rising, so he advised him to stop arraignment and go to the hospital. However, Xu Hongsheng said that it was an old attack, and he would be fine if he went home and took some medicine. In the evening, Xu Hongsheng dragged his tired body home and fell asleep. It didn’t take long for his condition to deteriorate sharply, with severe vomiting, and he was rushed to the hospital by his family. The doctor diagnosed him as uremia. This is the beginning of the scene …

At work, Xu Hongsheng dares to fight and fight. Engaged in criminal investigation for 7 years, he has participated in and solved more than 1,000 criminal cases, including 12 homicide cases, arrested more than 400 criminals of various types, and recovered economic losses of more than 5 million yuan for the masses. However, in life, Xu Hongsheng is an unqualified husband and father. Xu Hongsheng’s wife Ye Jinhui often complains that falling in love with Xu Hongsheng means falling in love with someone who doesn’t go home. Ten years ago, Ye Jinhui met Xu Hongsheng. After she got married, she found that the man she had entrusted for life was often "unreliable". One winter, my daughter had a high fever. Anxious Ye Jinhui called Xu Hongsheng, but Xu Hongsheng said that she was squatting and couldn’t leave. No way, Ye Jinhui had to go to the hospital with her child in her arms.

How many family gatherings, promised to be a good Xu Hongsheng, but was absent; How many times did he get a phone call in the middle of the night? He hastily put on his clothes and went out for several days. Because of this, his wife quarreled with Xu Hongsheng a lot, but every time he quarreled, Xu Hongsheng smiled in front of his wife and promised not to dare next time. But as soon as the phone call came, he immediately forgot the promise he had made before. In fact, my wife doesn’t know that Xu Hongsheng really loves the profession of police!

In this transnational pursuit, Xu Hongsheng was afraid that his wife would disagree and did not report his illness to his wife truthfully. It was not until he was taken to the hospital that his wife knew that his condition had deteriorated.

Xu Hongsheng’s wife has been with him all these days since he was hospitalized. She said that this is the longest time they have stayed together since they got married. Xu Hongsheng often says that his wife has half the credit in his military medal!

Who doesn’t want to have a healthy body, who doesn’t want to give his lover a safe harbor, and who doesn’t want to spend more time with his children. As a people’s policeman, how to choose when the people need it? Xu Hongsheng chose to charge first, because he always put the responsibility and mission on his shoulders first. Let’s say thank you to this "criminal investigation man of iron"!

Super preservative helps food to keep fresh for a long time.

Microbiologists at the University of Minnesota in the United States have recently discovered a super natural preservative that can kill all kinds of bacteria and keep food for a long time at room temperature. It is reported that this preservative is called "Bisin", which is naturally produced from some harmless bacteria. This preservative can prevent meat, fish, eggs and dairy products from spoiling, and it is equally effective for opened red wine and salad dressing. The food added with this natural preservative does not even need to be put in the refrigerator, and it can be kept for several years at room temperature. However, due to the different functions of vegetables and fruits, the preservative can not keep them fresh. The researchers said that this natural preservative is better than any previous one, because it does not destroy the nutritional components of food, and no chemical components are added to food. It is just a natural component. At present, researchers have applied for a patent for Bissin in the United States. Milk, sausages and sandwiches added with Bissin are expected to be on the market within three years.

Super preservative helps food keep fresh for a long time.

?Fresh food could be made to last for years after scientists discovered a natural preservative capable of destroying a whole class of bacteria, including E.coli and listeria.

Fresh food could be made to last for years after scientists discovered a natural preservative capable of destroying a whole class of bacteria, including E.coli and listeria.

There would also be no need to refrigerate produce treated with the preservative, called, bisin, which is produced by harmless bacteria.

They say that foods like milk, sausages and sandwiches containing the agent could be on the shelves within three years.

Ready meals, opened wine and fresh salad dressing could also be safely consumed long after they were bought, say scientists.

Researchers at Minnesota University in the US discovered the substance from a culture of a harmless bacteria, Bifodobacterium longum, commonly found in the human gut.

It is the first naturally occurring agent identified that attacks so-called gram-negative bacteria such as E.coli, salmonella and listeria.

Dan Sullivan, an Irish microbiologist who now works at the university, told The Sunday Times: "It seems to be much better than anything which has gone before. It doesn’t compromise nutrient quality — we are not adding a chemical, we are adding a natural ingredient."

He and his team have patented the substance in the US.

Bisin is related to nisin, which attacks gram-positive bacteria, and is used in the manufacture of processed cheeses and meats. As such, it is generally recognised as safe and would not have to be pharmacologically tested.

It would not be able to prevent fruit and vegetables from rotting, however, as they decompose in a different way.

Further research is now ongoing, looking at exactly how good it is at stopping bacteria from growing.

Meanwhile, a British wholesaler has begun to make sandwiches with a two-week shelf life, by replacing all the oxygen in the plastic packaging with nitrogen and carbon dioxide.

Ray Boggiana, a food technologist who helped develop the range for Booker, which supplies convenience stores, said: "The science is not new. It’s all about using a protective atmosphere in the packaging."

Six regional inspection centers of the Ministry of Environmental Protection were renamed as regional inspection bureaus.

　　BEIJING, Nov. 23 (Xinhua) According to the official Weibo news of the Propaganda and Education Department of the Ministry of Environmental Protection, the Ministry of Environmental Protection held a regular press conference in November today. Liu Youbin, inspector of the Mission Department of the Ministry of Environmental Protection, introduced that recently, the central editorial office approved the transformation of the environmental protection supervision centers of the Ministry of Environmental Protection in North China, East China, South China, Northwest China, Southwest China and Northeast China from institutions to administrative agencies dispatched by the Ministry of Environmental Protection, and renamed them the North China, East China, South China, Northwest China and Northeast China respectively.

　　Liu Youbin said that at present, the Ministry of Environmental Protection has issued a "three-set" plan for each supervision bureau, clarified its main responsibilities, internal institutions and staffing, and re-appointed the directors of each supervision bureau, and all work is progressing in a coordinated and orderly manner.

　　Liu Youbin said that since the regional supervision center was piloted in 2002 and fully established in 2008, it has played an active role in strengthening China’s environmental protection supervision and law enforcement, actively responding to environmental emergencies, and effectively coordinating cross-provincial pollution disputes. However, because it has always been a public institution, it has affected the authority of supervision and law enforcement. This time, the inspection center has completed the transformation to the inspection bureau as a dispatched administrative agency, which has solved the problem of the law enforcement identity of the inspection center and will effectively promote the modernization of the national environmental governance system and governance capacity.

　　Liu Youbin emphasized that the six regional supervision bureaus will further strengthen the function of "supervising government", work together with the State Environmental Protection Supervision Office to build a national environmental protection "supervising government" system, further improve the environmental protection supervision system, and provide a strong guarantee for the central environmental protection supervision work.

Salt-tolerant crops are promising in the future.

　　CCTV News:Experts said that in addition to rice, there are many salt-tolerant crops in China. At present, agricultural scientists are working hard to improve the salt and alkali tolerance of crops, and there is great potential for salt and alkali tolerance crops in the future.

　　At present, the types of saline-alkali land for sea rice cultivation in China are soda frozen soil saline-alkali land in northeast China, saline-alkali land around Bohai Sea, arid and semi-arid saline-alkali land in northwest China, saline-alkali land in coastal small watershed type, newly-born saline-alkali land in southeast China, and secondary saline-alkali land in degraded farmland in central China. Other salt-tolerant crops can also be planted in these places.

　　Liu Chunming, Dean of Peking University Modern Agricultural College:Different crops have different levels of salt and alkali tolerance, such as some sorghum and cotton, which have strong salt and alkali tolerance, such as typical Salicornia angustifolia and Suaeda wetland, which can grow at a concentration (medium) close to seawater.

　　Planting rice on saline-alkali land can improve saline-alkali land through long-term salt drainage, so that the goal of gradually turning saline-alkali land into fertile land can be realized.

　　Liu Chunming, Dean of Peking University Modern Agricultural College:Corn, wheat, soybean and rice are all being studied (salt-tolerant planting). In the past few years, we have been digging up some important resources to transform the salt-tolerant ability of our crops.

　　Founded in 1989, Beilun Middle School in Ningbo, Zhejiang Province is a young and energetic ordinary high school. The school has refined the concept of "people-oriented, adaptive development" to meet students’ diverse and personalized learning needs, so that every student can "find what he wants" and "become the best himself".

　　People-oriented, Create Characteristic Curriculum

　　Facing the new situation and new requirements, the school has built a high school curriculum system of "infiltrating humanities and cultivating science" on the original basis, and created a number of characteristic core courses with rich characteristics and great potential. The so-called "characteristic curriculum" is not only rooted in the existing conditions of the school, but also based on the internal needs of students, and it must face the future development direction. After careful design, a number of characteristic courses, such as robot education and mathematical modeling, emerged as the times require and became the window of school curriculum reform.

　　Entering the Robot Maker Center, the competition venue, honor exhibition area, robot building room, robot programming room and other areas are refreshing. Multi-functional subject laboratories can be used for robot course teaching, community activities, competition training and other activities. Since its establishment, Maker Center has been adhering to the concept of "STEAM Education", aiming at improving students’ interest in science, technology, engineering, art and mathematics, and improving students’ teamwork and problem-solving ability by promoting robot education. The school has trained specialized talents by offering "DIY (Do-it-yourself Robot)" elective course, carrying out robot club activities, participating in robot competitions, etc., and many talented students have emerged in mechanical design, program design, operation control, etc., and have achieved excellent results in various competitions at all levels. More importantly, the award-winning students discovered their self-worth through robot education and established their professional ideals.

　　The school takes innovative laboratories and subject classrooms as carriers to promote the construction of subject-specific courses, and constructs subject-centered characteristic courses that run through compulsory and elective courses, thus forming its own school-running characteristics. VEX (Robot World Championship) robot, programming, mathematical modeling, NS (local storm) street dance and other characteristic courses have been loved and recognized by more and more students from scratch, effectively promoting the development of students’ personal introspection intelligence and interpersonal intelligence.

　　Establish a school with excellent teachers and build a teaching and research community

　　In order to promote the development of school teachers, and strive to build a team of high-quality teachers with international vision, domestic leadership, noble ethics and exquisite business, the school has implemented three training projects of "blue", "backbone" and "Excellence" for teachers, and built a teaching and research community based on the trinity of individuals, teams and schools.

　　The "Blue Project" is aimed at new teachers, and the school strives to give new teachers a "good start", gain a firm foothold and grow rapidly for a period of three years. Concentrate on learning once a week, or invite famous teachers inside and outside the school to present their opinions, or watch the demonstration class of famous teachers collectively, or discuss themselves around the theme. At the same time, each new teacher is equipped with dual tutors for teaching and class management, and the training hours stipulated by the new teachers are implemented, and the tutor responsibility system is implemented; Targeted professional competence plan will be carried out, and professional training and assessment will be organized by discipline teaching and research staff to comprehensively improve teachers’ classroom teaching ability and class management ability.

　　Relying on the young teachers’ salon, the "backbone" project actively explores the superior resources in the school, integrates the potential strength of the team, conducts activities once a month, and simultaneously implements "please come in" and "go out". The Young Teachers Salon has set up a special secretariat to comprehensively improve the teaching ability of young and middle-aged teachers under the guidance of the Scientific Research Department, cultivate teachers’ sense of identity in education, optimize teaching design, teaching implementation and teaching evaluation, implement differentiated education according to students’ characteristics, and promote the reform of classroom teaching and learning methods by applying information technology.

　　The "Excellence" project takes the famous teacher’s studio as a platform to enhance the leading role of the school’s famous teacher’s studio and famous teacher’s workplace. According to the working idea of "building a platform, sharing resources, pairing mentoring, integrating teaching and research, basing on the classroom and growing rapidly", focus on curriculum reform and educating people; Expand the educational vision of teachers, help them to concise, summarize and reflect on teaching experience, update teaching concepts and form teaching styles.

　　On this basis, the school has continuously explored research approaches that are in line with the actual situation of the school and students, built a community of teaching, research and training, actively created brand disciplines at the city and district levels, improved the discipline construction ability, and promoted the discipline construction and teacher development of the school and even the whole region.

　　Educating people with characteristics and establishing a home-school consortium

　　The school has continuously deepened the "tutorial system for all students’ growth".

　　Adhering to the educational philosophy of "caring for every student as much as possible, and making students succeed as much as possible", we strive for a training environment of "all teachers are mentors and all students are cared for" to maximize the overall quality of students. Emphasis is placed on the diversified, developmental and procedural evaluation of students, guiding teachers to actively participate in students’ learning process, and fully stimulating students’ active internal drive and subjective initiative in learning life.

　　With the development of the times, it has become the consensus of modern education to strengthen the joint efforts of schools, families and society to educate students. The school has established the Parent Development College, actively exploring various forms of family education guidance, and promoting parents to form correct family education concepts and scientific family education methods. Aiming at the content of family education guidance, the school has set up a comprehensive teaching team to undertake the teaching work of the parents’ growth college. Psychological teachers are responsible for the guidance of family parent-child construction, emotional management, self-confidence, personality development and adolescent sex education; The class teacher undertakes the guidance of school life adaptation, academic self-planning and daily relationship handling; Excellent parents’ representatives shall provide guidance on legal knowledge, physical health knowledge, vocational education and future planning. The school actively provides all kinds of learning and training opportunities for teachers, regularly invites excellent family education experts to give lectures, organizes teachers to participate in seminars inside and outside the province, and conducts various forums, salons, online exchanges and other activities in the school to further improve the level of teachers.

　　The Parents’ Development College carefully designed activities and improved the curriculum system, which was well received by parents. On the basis of offering regular courses, the School of Parent Development has developed a series of required salons entitled "Smart Parents, Youth and Health", covering how to establish a good relationship with children, actively pay attention to children’s needs, and communicate effectively with children. In view of the typical problems encountered in students’ growth, the Parents’ Development College has developed a variety of special salons, such as "Let go of the burden and do whatever you want — — How to help children face the pressure of study ""Goals and planning — — Stimulate children’s inner learning motivation ". All kinds of special salons form a "menu", which parents can choose independently according to their actual needs. The school has been awarded the pilot unit of the national youth health parent training program, the youth health education base of Zhejiang Family Planning Association, and the first-class psychological counseling station of primary and secondary schools in Zhejiang Province. As the position of the school’s family education guidance, the Parents’ Growth College provides an important guarantee for the school’s education and teaching, which better meets the educational needs of parents and creates a better educational ecology for the development of students.
