Since the beginning of January this year, residents of Weicheng Town, Guiyang City, located in the mountainous area of Guizhou Province, have often seen a drone shuttle through the town. Under the belly of the plane, there was a box with the words "China Post". The local people later learned that this drone was used by the post office in the town to deliver mail to the surrounding mountain villages. Beijing Youth Daily reporter learned from the local post office on the 15th that this drone now flies twice a week, and it will be promoted if it works well in the future.

　　Postman part-time drone operator

　　On the morning of 15th, Wang Hua, a staff member of Weicheng Post Sub-bureau in Guiyang, took his drone to an open space near the town, and prepared to deliver newspapers and some mails to five villages around the town.

　　Wang Hua is a postman. He used to ride a motorcycle to deliver mail to several surrounding villages three times a week. Because the mountain road is rugged, although the distance is not far, it takes a whole day to deliver it every time. Since the beginning of January this year, Wang Hua has added a new task, which is to operate drones to transport mail.

　　"Our economy is not developed here. Many people have never seen drones, so many people gathered around to see them when they first started flying. Some old people asked us about the timetable for flying drones and came to see them several times." Wang Hua said.

　　Wang Hua said that he is driving a drone, but in fact the main operation is not done by him. He is mainly responsible for loading mail on the drone and then checking the battery. The flight route has long been set by the company that developed the drone. All he has to do is scan the QR code on the plane with his mobile phone, and then click the start button on the mobile phone, and the plane can fly according to the pre-designed route.

　　"It used to take a whole day to send the mail from these villages by motorcycle. Now the whole route is flown by drones, which is more than an hour." Wang Hua said.

　　Flying to every village requires changing batteries.

　　Director Chen Zhongxiang of Weicheng Post Sub-office told the reporter of Beiqing Daily that at present, there is only one drone in the town post office, and they selected five villages, namely Yingyan, Yinqiao, Maixiang, Xingguang and Lianhua Temple, as delivery pilots. Chen Zhongxiang said that these villages were chosen because they are relatively remote, and it takes too long and the road is dangerous to send mail into the village by manpower.

　　Chen Zhongxiang said that the UAV they are using now has a diameter of more than 1 meter and six propellers. In theory, it can carry about 7 kilograms of goods. However, for safety reasons, the stipulated delivery weight is no more than 5 kilograms, and the flying distance between villages is about 10 minutes. Every time you fly to a village, you need people from the village to help replace the new battery, and then you can fly to the next village. The whole journey is a "relay" process.

　　"The plane must be fully charged before it can take off. The last time we saw the power of the plane was 82%, we felt that we could complete a flight, but after the start, the plane still could not take off. This may be the design made by the aircraft research and development enterprise for the absolute safety of the aircraft." Chen Zhongxiang said.

　　Temporarily unable to replace manual delivery.

　　According to the staff of the UAV R&D company, when the plane lands, it needs to lay a red and blue positioning carpet at the landing site. The UAV is equipped with a sensor in the vertical direction. When it searches for the positioning carpet, it will land accurately. Location.

　　Chen Zhongxiang told the reporter of Beiqing Daily that it was not the decision of the town post office to equip the town post office with drones, but the higher authorities chose the Weicheng post office as a pilot. If the use effect is good in the future, it will continue to be promoted.

　　"Many people in the village felt particularly fresh when they saw the plane at first, and the people in charge of managing the plane in each village also had a WeChat group. When the plane took off and landed, everyone would inform each other."

　　Annabelle of Xingguang Village Committee is one of the managers of this drone. Every time he receives the mail from his village, he also needs to replace the plane with a new battery. "If the battery is not fully charged, the plane can’t fly, but there will definitely be no forgetting to charge the battery. Everyone will remind each other when they have WeChat groups."

　　Chen Zhongxiang said that in the past, the postman of the post office had to go into the mountain three times a week, but now it has been reduced to twice a week, while the drone now flies twice a week. If the effect is good in the future, it will increase the flight frequency. "But due to the limitation of load, drones can’t completely replace the postman now, and everywhere they go, they need people to get express delivery for batteries. There are still some troubles. It would be nice if these jobs can be replaced by machines in the future."

Cctv newsOn July 23rd, the State Council Joint Prevention and Control Mechanism held a press conference on the safety and effectiveness of vaccines in Covid-19. According to the report of the World Health Organization, the newly confirmed cases in the western Pacific where China is located increased by 37% last week, which is the fastest growing region in the world. Omicron’s BA.5 sub-branch has spread to more than 100 countries and regions around the world, resulting in an increase in the number of infections, hospitalizations and severe cases, and the pressure on China’s foreign countries to prevent imports is increasing.

Recently, the local epidemic situation has shown a trend of multi-point distribution and frequent occurrence. In some areas, the epidemic spillover has not been completely blocked, and the prevention and control situation is severe and complicated.

We must unswervingly adhere to the general strategy of "external defense input, internal defense rebound" and the general policy of "dynamic clearing". The areas where the epidemic occurred should deal with the clustered epidemic according to the local situation, concentrate resources and strength to quickly put it out, and quickly curb the spread of the local epidemic; Border areas and entry cities should strictly implement various measures for external defense input, strictly manage in a closed loop, and resolutely avoid the destruction of defense and the overflow of epidemic situation; Areas where no epidemic has occurred should continue to do a good job in normalization prevention and control, and maintain the efficient operation of the emergency response command system.

Covid-19 vaccination should be continued.

Last weekend, with the release of "Feng Shen I", "Super Family" and the national screening of "Enthusiasm", it added another fire to the already hot summer movie market. Although there are films that are not as good as expected, there are more excellent works that exceed expectations.

Disappeared She took the lead, Three Wan Li in Chang ‘an, In the Octagonal Cage were full of stamina, The First Part of Gods was well received, and The Warmth was warmly reflected.

One domestic film after another has completely ignited the film market in China, and this year’s summer box office is expected to break the box office record of 17.653 billion yuan created by the summer file in 2019.

On July 21st, the Mahua FunAge comedy "Super Family" directed by Song Yang and starring Allen and Shen Teng was released, which earned 87.33 million yuan at the box office that day, and unexpectedly won the one-day box office champion. However, its reputation was not satisfactory, and it was impossible to reproduce the hot box office in Moon Man in the same period last year.

These two films were originally considered as the most important domestic commercial films in the second half of this summer, but their box office performance in the first weekend was not as good as expected, which made people slightly worried about whether the China mainland film market could continue to be hot in August.

The east is not bright and the west is bright. Last Saturday and Sunday, the domestic comedy inspirational film "Enthusiasm", which was scheduled to be released on July 28, was released in the country one week ahead of schedule. The touching and funny story won enthusiastic response from the audience and restored confidence in the August film market.

As of the press release of The Vane of Film and Television, the box office in July this year has reached 6.656 billion yuan, which is only one step away from the highest box office record of 6.966 billion yuan in China film history created in July 2018. There are still eight days left, which will surely set a new record.

Among the new films released last weekend, the biggest surprise was the hip-hop comedy "Enthusiasm" directed by Dapeng and starring Bo Huang and YiBo. This is the second film directed by Dapeng released this year.

On March 10th, "Keep You Safe" starring Dapeng, Li Xueqin, Andrew and Wang Xun earned 700 million box office and 7.7 points for Douban. "Enthusiasm" is even worse in terms of word of mouth, starring lineup and release schedule.

The film tells the story of little people pursuing their dreams and fighting back. The theme of street dance is not only novel, but also meets the aesthetic needs of young audiences. The whole film is both exciting and tearful. Personally, it is the best film directed by Dapeng so far.

"Enthusiasm" has the right casting, and the scene of the street dance competition is very explosive and youthful. YiBo gave full play to his dancing skills and presented his best performance on the big screen to the audience.

As always, Bo Huang’s performance is grounded and humorous, and she also shows off her dancing skills in the film. He and Yun-peng Yue also made a lot of jokes in the film. When Liu Mintao’s mother sang "Zhang San’s Song" in the film, I saw my eyes moist.

Such an inspirational film, which is burning, touching, funny and realistic, is likely to lead the second half of the summer file in August and this year, and the box office will hit 2 billion or even 3 billion yuan.

According to the data of Cat’s Eye Professional Edition, up to now, the summer box office in 2019 and 2018 ranked first and second in the box office of China film history in the same period. By analyzing the box office rankings of single films in the past two years, we can find that five films have grossed more than 1 billion yuan.

At present, three films, Disappeared She, Trapped in an Octagon Cage and Long March, have grossed more than 1 billion yuan this summer, and the films that are expected to exceed 1 billion yuan in the second half are expected to be Feng Shen Part I and Enthusiasm. Meg 2, which was released on August 4th, is likely to have a good reputation. In this way, there are expected to be as many as six films with a box office of 1 billion this summer.

In 2019, Ne Zha, the champion of summer box office, earned 4.706 billion yuan at the box office. In the summer of 2018, Dying to Survive, the box office champion, earned 3.098 billion yuan, and the runner-up "The Richest Man in Xihong City" earned 2.52 billion yuan.

This year’s summer file, "Disappeared She" currently ranks first at the box office with 3.465 billion yuan, which has surpassed Dying to Survive. The box office of octagonal cage is currently close to 2 billion yuan, and the final box office will definitely exceed 2 billion yuan. Cat’s Eye’s latest forecast that the final box office of Chang ‘an Three Wan Li will be 1.94 billion yuan.

If "Enthusiasm" can reach 23 billion yuan at the box office after its release, and other heavy films such as Meg 2’s "Put all your eggs in one basket", "Assassination Storm" and "Learning Dad", this summer’s box office is likely to break the highest box office record in China’s film history at the same time.

A single flower does not make a spring. Compared with Ne Zha’s dominance in the summer of 2019, this summer’s top films are richer in themes and types, and the box office structure is more reasonable. Looking forward to China movies getting better and better!

　　Editor’s note:With the improvement of living conditions and the strengthening of health awareness, more and more people enter the fitness industry. Some people exercise to gain muscle, while others exercise to lose weight. What benefits can fitness bring us? Today, people’s network health talks with you.

　　Strength training, the benefits are not only muscle gain.

　　1. Prevent and improve anxiety and depression. A study of more than 1,800 people at Harvard University found that people with mild to moderate depression who do strength training at least twice a week have significantly less symptoms than those who don’t. This is because strength training increases the blood flow in the brain and releases brain hormones that enhance mood, such as norepinephrine and dopamine.

　　2. Improve cognitive function. A study published in the journal Molecular Psychiatry shows that people who do strength training twice a week have significantly improved their cognitive function after 18 months. Researchers say that strength training can thicken a part of the gray matter in the brain that is often affected in early Alzheimer’s disease.

　　3. Reduce the risk of falling. Falling is the main cause of death among people over 65 years old, and the weakness of lower body strength, especially leg strength, is the main risk factor. In a review of 17 studies published in the British Medical Journal, it was found that the risk of the elderly who participated in the fall prevention exercise program, including strength training, decreased by more than one third.

　　4. Reduce the risk of type 2 diabetes. A Japanese study published in the Journal of Diabetes Research shows that the elderly over 60 years old have undergone low-intensity resistance training twice a week for 16 weeks, and their blood sugar levels have improved significantly. Su Hao said that the process of human aging itself is caused by insufficient energy supply of cells, and strength training can delay cell aging and improve sugar metabolism.

　　5. Prevent heart disease. A study of 4086 adults by the American Heart Association in 2018 showed that strength training can protect health better than aerobic exercise. Last year, a study published in the journal Medicine and Science in Sports and Exercise showed that less than one hour of resistance exercise per week can reduce the risk of metabolic syndrome (such as hypertension, high cholesterol and elevated blood sugar). "This is because strength training can increase the body’s sugar and lipid metabolism." Su Hao explained.

　　6. Relieve the symptoms of chronic kidney disease. Muscle atrophy is one of the symptoms of chronic kidney disease. A study published in the American Journal of Physiology last year found that patients who combined aerobic exercise with strength training three times a week significantly increased their muscle strength and overall physical fitness, and other symptoms of patients with kidney disease, such as itching, shortness of breath, impotence and muscle spasm, were also relieved. Patients who only do aerobic exercise have no obvious effect.

　　Four movements can reduce underarm fat

　　Some women find that there are two lumps of meat under their armpits when they are wearing clothes, which greatly affects their appearance and worries them. In this regard, Tan Sijie, a professor at the Department of Sports Human Science of Tianjin Institute of Physical Education, said that this excess meat is mostly false breast milk, that is, the subcutaneous fat in front of or under the armpit increases, which can be improved through the following four actions to make the body look better.

　　1. Back flexion: Sit on the bed or mat, hold the ankle with both hands, touch the ground with the elbow joint, bend the upper body forward, fully extend the back, and try to make the chest touch the thigh; After 6 ~ 8 seconds, restore and do it for 10 ~ 12 times.

　　2. Flexion and extension of the back of the neck: stand up straight, hold the barbell piece with both hands, and elbow height lifts it, then lift the barbell piece upward until the arms are straight, and then restore it. Do it 8 times in a row and do 4 ~ 6 groups.

　　3. Push the wall exercise: hold the wall with both hands upright, stand with your body leaning forward against the wall, bend your elbows and push the wall to make your body upright, and then stop for a while and restore. Do it 20 ~ 30 times in a row, a total of 2 groups.

　　4. Bend your arms and strengthen your chest in a prone position: kneel on the floor with your arms straight, then bend your arms down until your chest hits the ground. When bending your arm, pay attention to putting your body’s center of gravity on your wrist, and support your body weight with the strength of your arm and wrist. Do it 8 ~ 10 times repeatedly.

　　Exercise since childhood, and you will get less cancer all your life.

　　An epidemiological study by the University of Sao Paulo in Brazil shows that from the age of 17, the health benefits of 60 minutes of moderate physical exercise every day will accumulate for a lifetime.

　　In order to investigate the causes of chronic diseases and the long-term effects of physical activity, nutrition, hormones and environment on the development of diseases, the research team conducted a follow-up survey on 28,000 American women. The researchers collected the physical exercise data provided by the participants in adolescence (12-22 years old), and then followed up their physical examination results and exercise every year. The relationship between physical activity in adolescence and the risk of adenoma was tested by logistic regression model. It was found that the risk of adenoma was reduced by 7% in people with more physical activity in adolescence (more than 60 minutes of exercise every day). Starting to exercise in adulthood (23-64 years old) reduces the risk by 9%; Those who have been exercising from adolescence to adulthood have reduced the risk by 24%. The findings were published in the British Journal of Cancer.

　　Researchers say that the health benefits brought by sports will have cumulative effects with age. At a time when unhealthy lifestyles such as sedentary, smoking, drinking and overeating are widespread, this study aims to enlighten the public that educating children to form the habit of insisting on exercise from adolescence will benefit them for life.

　　Exercise in the gym is step by step.

　　Step 1: Warm-up (10 ~ 15 minutes): As soon as many novices enter the gym, they can’t wait and immediately start strenuous exercise, ignoring an important link — — Warm up. Wang Anli said that warm-up activities can not only reduce sports injuries, but also improve sports ability, improve joint flexibility and mobilize internal organs.

　　Warm-up activities are based on body fever, slight sweating and no fatigue, and mainly low-intensity activities. For example, you can do some knee stretching exercises first, and then jog for a few minutes, preferably outdoors; Walk for a while after jogging, and increase the swing range of your arms appropriately; After feeling the temperature rise, do some stretching exercises. In addition, warm-up activities can also be carried out in a targeted manner. For example, before spinning training, you can do opening and closing jumps, lunges and leg stretching to mobilize breathing and leg muscles.

　　Step 2: Training (about one hour). Many people run on the treadmill for an hour as soon as they enter the gym, which makes it difficult to carry out strength training later because the energy has been exhausted. The correct order is: anaerobic first, then aerobic, such as dumbbell bending, squat and other anaerobic exercises to improve metabolic function, and then aerobic exercise, the exercise effect is better, but pay attention to the fact that the total time of the two should not exceed 1 hour.

　　When training equipment, you should practice big equipment first and then small equipment, otherwise, there may be no stamina; We should also follow the principle of gradual progress, starting with a small number of pounds, such as 1 pound, 3 pounds and then rising to 5 pounds or more; The number of practice groups starts from 2 groups, and then gradually increases, with a group of 12~15 times. In addition, when practicing strength, novices should first choose fixed equipment, such as bench press with Smith machine, feel muscle contraction and learn to exert strength, and then practice free weight training, such as lifting barbells from the ground.

　　Step 3: Tidy up or relax (5 ~ 10 minutes). After the training, finishing activities with a small amount of exercise for 5 to 10 minutes can make the muscles recover faster and prevent muscle spasms, injuries and soreness. For example, you can walk fast or run 300 meters and do stretching activities. In addition, relaxation activities are also targeted, that is, which parts of muscles are used more during exercise, where to relax. For example, spinning training uses more muscles in legs and shoulders. After training, you can do leg press, turn shoulders and other actions.

　　According to media reports, recently, a "shared sleeping cabin" in Zhongguancun, Beijing was closed, and the "shared sleeping cabin" in Yinhe SOHO also temporarily stopped operating.

　　On the afternoon of the 18th, the reporter from Zhongxin. com came to the "Enjoy Sleeping Space" experience store on the second floor of Zhonggang Plaza Venture Corporation in Zhongguancun Street and found that the door was indeed closed, and the words "System upgrade, suspended use" were posted outside the door.

　　Subsequently, the reporter scanned the QR code, and the mobile phone popped up a "system update and maintenance" prompt, which could not be used normally.

　　At the same time, according to media reports, similar situations have occurred in the experience points in Shanghai and Chengdu. Contrary to the fate of bike-sharing, which was quickly spread across the country before, "shared sleep" was embarrassed to leave before it was hot.

　　Person in charge: it is expected to be officially launched after the initiative to shut down.

　　Why did the "shared sleeping cabin" stop using? Is this behavior done by the police?

　　Dai Jiangong, co-founder and CEO of Xiangshui Technology, denied the statement that it was "seized by the police" on the Internet.

　　Dai Jiangong told the media that the company has not received any rectification opinions or seizure notices from the relevant departments since the pilot at the end of May, but for the sake of long-term development, it is necessary to communicate with relevant departments, so it took the initiative to suspend all "shared sleeping cabins" in Beijing.

　　He emphasized that the company has put more than a dozen "shared sleeping cabins" in Beijing to test and collect user feedback, but it has not been officially launched. The positioning of this project is not hotels or renting beds, but to provide a comfortable space for office white-collar workers in a relatively closed office building, which is not open to the public at night.

　　In addition, the person in charge also told the media that there is no approval and license from relevant departments for the "shared sleeping cabin" at present, but the local industrial and commercial administration departments have been invited to check it out and explain the situation to them. The company will be officially launched after obtaining permission from relevant departments such as health and fire protection.

　　Lack of supervision "shared sleep" has many hidden dangers.

　　In view of the emergence of the new concept of "shared sleep", there are both support and opposition.

　　Supporters generally believe that this kind of sleeping cabin is simple to use and low in price, which meets the needs of many office workers for a nap. At the same time, some opponents believe that the health and safety hazards of sleeping cabin are huge.

　　In this regard, Su Haopeng, a professor at the Law School of the University of International Business and Economics and director of the Consumer Protection Law Research Center, said in an interview with Zhongxin.com that unlike bike-sharing, the "shared sleeping cabin" caused great controversy as soon as it appeared, mainly because its industry was different from that of bike-sharing.

　　"Although the operator emphasizes that the sleeping cabin is only used by the internal staff of some office buildings, and it is not a 24-hour service, it is provided for others to rest, and it is a market-oriented and profitable behavior. It should be included in the scope of the hotel industry from the perspective of economic format." Su Haopeng emphasized that it is necessary to manage the "shared sleeping cabin" according to the hotel industry from the service content.

　　He emphasized that the operation of the "shared sleeping cabin" involves a series of management issues such as fire protection, sanitation and public security. If you conduct business activities without the supervision of any relevant departments, it is a violation of the relevant laws and regulations on industrial and commercial management.

　　Zhu Wei, a professor at China University of Political Science and Law and an expert member of the internet society of china Sharing Economy Working Committee, also believes that in China, the operation of hotels and guesthouses needs the approval of many departments, such as industry and commerce, health and fire protection, but today’s "shared sleeping cabins" do not have these qualifications, which hides many hidden dangers. These "shared sleeping cabins" must obtain the relevant qualifications of offline hotels to ensure the health and safety of users before they can go online.

　　Under the upsurge of "sharing economy", what can be done with people "share”？

　　The embarrassing experience of "shared sleeping cabin" has also made people start to think about whether the products that have sprung up under the upsurge of "sharing economy" really belong to the sharing economy, or are they just in the name of "sharing"?

　　In Su Haopeng’s view, "sharing economy" is not an accurate legal or policy concept. "In a broad sense, as long as a commodity or service is used by an unspecified majority, it can be called ‘ Sharing economy ’ 。”

　　He believes that the current "shared sleeping cabin" is basically the same model as bike-sharing, and it can be included in the broad sense of "shared economy", which is a new economic form.

　　On the other hand, not everything is suitable for "sharing". This kind of "shared sleep" which is in seamless contact with the body is difficult to guarantee in terms of safety and hygiene, and its rationality is worth considering.

　　Zhu Dajian, director of the Institute of Sustainable Development and Management of Tongji University, also believes that sharing is very fashionable now, but not every kind of "sharing" has a stable and long-term demand, and not every new thing covered with "sharing" has innovation, which still needs to be tested by the market and society.

　　In his view, from sharing among acquaintances to sharing among strangers by mobile payment, the era significance of sharing economy lies in breaking "everything should pursue possession" and becoming "not seeking possession but seeking use". (End)

　　Wu Zhenyu, the winner of Golden Horse in Taiwan Province, is famous for his outspoken and outspoken attitude in the entertainment circle. Yesterday, when he came to Shanghai to walk for a brand, he threw an amazing view in public. He bluntly said: "The lower the education level, the greater the probability of getting rich." Gu Xiaoming, a professor at Fudan University, thinks that Wu Zhenyu’s theory that it is difficult to get rich by reading is biased, but it also has some truth. "There are indeed many rich people who have no education, but they have tacit knowledge. Reading is not useless, the key is not to die reading. "

　　The theory of "getting rich" is surprising.

　　Yesterday, Wu Zhenyu appeared in Shanghai as the image spokesman of worship, but the media was most concerned about his film and television works. In this regard, Wu Zhenyu said that he and a screenwriter friend recently completed an English novel, "adapted from a screenplay." He also revealed that he had advised his friend to quit his job as a professor and concentrate on writing this novel. However, his reason is surprising. "I think reading too much in college will paralyze my brain, because books are all old things."

　　In the subsequent interview, Wu Zhenyu threw out the theory that it is difficult to get rich by reading. "I found that the lower the education level, the greater the probability of getting rich. Go and see how many rich people have read many books, and Lang Lang only plays the piano. " When the media questioned that Lang Lang had gone to college, he responded: "It’s an art school, just playing the piano." He also said bluntly that he would use this view to educate his children.

　　Currently focusing on TV dramas.

　　Wu Zhenyu’s memorable roles in film and television dramas are mostly malicious and bad characters. In this regard, Wu Zhenyu said that he didn’t care about always playing "bad guys" and didn’t deliberately want to transform. He also smiled and asked, "aren’t there still many actors who are bent on playing the bad guys?"

　　Asked about his latest work, Wu Zhenyu revealed that he was currently filming a TV series about medical ethics in Qingdao. He said with a smile: "I am’ the countryside surrounds the city’. Now many actors who make TV dramas are proud of making movies, so I will make TV dramas. " For the invitation of TV series, Wu Zhenyu is open to all. However, his agent said that Wu Zhenyu’s interest in TVB was not great, which was not that he was dissatisfied with TVB. The main reason was that TVB’s pay was too low, because they were all contracted artists.

　　Wu Zhenyu admits that he is not used to the style of filming by mainland directors. "I like to be able to restore a complete scene when filming. However, when filming in the mainland, there were too many crew members. As soon as the filming started, everyone came out at once, and their breathing could be heard at the scene. "

　　Experts’ Interpretation of Wu’s "Reading Theory"

　　Regarding Wu Zhenyu’s theory that it is difficult to get rich by reading yesterday, Gu Xiaoming, a professor at Fudan University, bluntly said, "Reading is certainly useful, but now there is something wrong with our education. Nowadays, experts and scholars are always’ this is Harvard University’. It seems that there is no other knowledge in the world except these famous universities. "

　　He later thought that Wu Zhenyu’s theory of "reading is difficult to get rich" also had some truth. "Indeed, many of our successful businessmen have not received higher education. But these self-made entrepreneurs have tacit knowledge and are rarely bound by the frame. " Gu Xiaoming concluded: "Reading is both useful and useless. It’s definitely not good to just gnaw at dead books. It takes 20 years for the theory of textbooks to accumulate, 10 years for all of them to be reviewed, 10 years for printing, distribution and promotion, and a textbook can often be used for another 10 years. Adding up the knowledge in textbooks and the knowledge in reality, it is actually decoupled for 50 years. Therefore, the key to reading is to combine knowledge with practice.

Q:What are the nutrition and health problems of Shanghai residents?

A:It is not eating too much, but the dietary structure is unreasonable, mainly because there are less plant foods (cereals/vegetables/fruits) and more animal foods (livestock and poultry meat); The proportion of fat in diet is high, and the energy provided by fat is 38.0%, which exceeds the recommended upper limit of 30%.

First, the problem of overweight and obesity is prominent. As far as diet is concerned, the problem is unreasonable dietary structure (more animal food/less plant food, high fat ratio).

The overweight and obesity rate of Shanghai residents is 44.1%, which is close to the average level of cities in the national nutrition monitoring results from 2010 to 2013 (the overweight and obesity rate of big cities in China is 47.8%). Shanghai residents don’t eat too much. The energy intake of Shanghai residents is lower than that of 10 years ago, which may be related to the change of lifestyle, people no longer engaged in manual labor, and the decrease of energy demand, as well as the trend of energy intake of people found in international and our country’s nutrition monitoring.

There are many factors that cause obesity. As far as dietary factors are concerned, the main problem of Shanghai residents is the unreasonable dietary structure. The traditional Chinese diet mainly takes plant food (cereal is the staple food), which is rich in dietary fiber, which is beneficial to prevent chronic diseases. However, current monitoring shows that the intake of animal food in residents’ diet greatly exceeds the recommended level, while the intake of cereal has dropped significantly in the past 10 years, and the intake of vegetables and fruits is insufficient. Such a dietary structure contains less dietary fiber, which is not conducive to the prevention of chronic diseases. At the same time, the absorption rate of different foods in the human body is different. The current dietary structure may increase the absorption rate of food, which may lead to the increase in the overweight and obesity rate of residents.

On the other hand, the monitoring also found that the percentage of energy provided by residents’ fat was 38.0%, which was close to the average level of big cities (37.2%) in the national nutrition monitoring results from 2010 to 2013. In the recommendation of Dietary Guidelines for China Residents, the percentage of energy provided by dietary fat does not exceed 30%, which has now exceeded the upper limit by a lot. Animal foods, especially livestock and poultry meat, contain more saturated fat. The monitoring results show that the intake of livestock and poultry meat in Shanghai residents’ animal foods exceeds the recommended 61%.

Second, suggestions on unreasonable dietary structure: increase plant food, reduce animal food, and replace some livestock and poultry meat with aquatic products.

1. Increase the intake of plant foods such as cereals, vegetables and fruits.

In view of the dietary nutrition problems found by monitoring, it is suggested that residents gradually improve their dietary structure and increase the intake of plant foods such as coarse grains, vegetables and fruits. Usually, people’s food intake in a day is relatively stable. If the intake of plant food increases, the intake of animal food will decrease accordingly.

It is worth noting that in the past 10 years, the grain intake has dropped significantly. At present, the grain intake of residents is 189.6g, which only reaches 69% of the recommended intake (the recommended intake is 200-300g, compared with 275g/2200kcal). It is suggested that residents should increase the intake of cereals, and at the same time, they should match the thickness, and pay attention to increasing whole grains and miscellaneous beans, because cereals with high processing precision will cause high blood sugar response. Rice can be eaten with whole grains (brown rice), miscellaneous grains (oats, millet, buckwheat, corn, etc.) and miscellaneous beans (red beans, mung beans, kidney beans, flower beans, etc.).

2. Reduce animal food, you can choose aquatic products to replace some livestock and poultry meat.

At the same time, it advocates food diversification. In view of the problem of excessive intake of livestock and poultry meat by Shanghai residents, it is recommended that residents can choose aquatic products to replace some livestock and poultry meat. Livestock and poultry meat contains saturated fat, which is a risk factor for cardiovascular diseases and tumors. Aquatic products contain unsaturated fat, which is beneficial to health.

Finally, it is recommended to choose at least 12 different foods every day to prevent the risk of chronic diseases caused by possible nutritional deficiency or excess.

Third, the rising trend of overweight and obesity among students has not been curbed, and sugary drinks are widely consumed. Excessive drinking of sugary drinks is one of the risk factors of overweight and obesity, so it is suggested that students should be controlled to drink sugary drinks.

There are many factors that cause overweight and obesity, except the unreasonable dietary structure mentioned just now. In addition, there are differences between primary and secondary school students and adults. This monitoring found that it is common for primary and secondary school students to drink sugary drinks. 74.6% primary and middle school students drink sugary drinks more than once a week, and 36.5% primary and middle school students often drink them. It is more common for high school students to drink sugary drinks, and 62.5% of them often drink them. There are also a few students who drink sugary drinks every day. 20.9% of primary and secondary school students drink sugary drinks more than once a day, and the proportion of high school students is even higher. There are 41.5% of high school students who drink sugary drinks more than once a day.

The Dietary Guidelines for China Residents (2016 Edition) recommends that children and adolescents prefer boiled water to sugary drinks every day. Drinking sugary drinks does not produce satiety, resulting in excessive intake of sugar and energy. According to literature reports, excessive intake of sugary drinks can easily lead to various diseases such as obesity, diabetes, metabolic syndrome and blood lipid problems.

It is suggested that primary and secondary school students should be restricted from drinking sugary drinks, students should be encouraged not to drink sugary drinks, and extra sugar and energy intake should be reduced. Parents and school teachers should be aware of the influence of sugary drinks on children’s overweight and obesity. It is suggested that schools should encourage students not to bring sugary drinks into school, schools should not provide sugary drinks for sale, and widely carry out health knowledge propaganda on restricting sugary drinks in schools.

4. The intake of oil and salt in Shanghai has obviously decreased in recent 10 years, thanks to the measures to control oil and salt in Shanghai, but the current intake of oil and salt is still higher than the recommended level, and it is necessary to continue to strengthen intervention.

Our diet is mainly salty, and frying, frying and frying are common cooking methods. Excessive intake of cooking oil and salt in the diet is one of the important factors causing hyperlipidemia and hypertension. According to the monitoring results, the daily per capita intake of cooking oil and salt is 36.4g and 7.5g, respectively, which are 21% and 24% lower than the survey data 10 years ago, and 11% and 16% lower than the national average of big cities.

We compared the trend of oil and salt intake in Shanghai in recent 10 years, and found that it was obviously decreasing. At the same time, we also looked at the trend of oil and salt intake in urban areas of China in recent 10 years, but there was no obvious downward or upward trend, and it remained basically stable. This difference in trend should be attributed to the health education and intervention on oil and salt control led by the Shanghai Municipal Government in the past 10 years, such as the distribution of "salt control spoons" and "oil control pots" throughout the city in 2008 and 2009, so that the vast number of Shanghai residents can truly experience the quantitative concept of "eating less salt and putting less oil" and turn the traditional propaganda slogan into a reality for residents.

Residents’ intake of cooking oil and salt decreased obviously, thanks to various health education and intervention led by the Shanghai municipal government in the past 10 years, which is a good aspect. On the other hand, we should also see that the intake of oil and salt for eating at home is still higher than the recommended standard. The recommended daily intake of oil and salt is no more than 25 grams per day, and the current intake of cooking oil and salt for residents is still far from the recommended level. Measures to control oil and salt should continue to be strengthened.

5. At present, it is common for residents to eat out (61% residents eat out). In addition to traditional intervention in family cooking, institutions such as restaurants and canteens should be intervened in the future.

From the monitoring data, we also found that the current rate of residents eating out is 61%, which is much higher than the national rate of urban residents eating out of 42%. The people who eat out in Shanghai are mainly young people aged 15-44. People used to eat at home, but now they eat out more and more. We can also see from ourselves that prepackaged foods (that is, packaged food, such as cakes, bread, sausages, etc.) has become a new choice. The development of science and technology has made life more convenient, and the rise of new consumption methods such as take-away and online shopping has affected the traditional family cooking habits. These changes pose new challenges to traditional nutrition intervention strategies.

The monitoring also found that the sodium intake of Shanghai residents was 4927.2mg, which was nearly 1.5 times higher than the recommended level. Excessive intake of sodium is closely related to the increase of blood pressure and the occurrence of hypertension. At present, the sodium intake of residents through salt accounts for 3/5 of the total sodium intake. Besides salt, sodium comes from salty condiments (such as soy sauce, monosodium glutamate, etc.), semi-finished dishes, pickled products, snacks, etc. (common sweet preserves also contain a lot of sodium), and vegetables also contain a certain amount of sodium. In the past, we actively advocated reducing salt intake, which can reduce sodium intake. As mentioned just now, residents’ eating style has changed. More and more people eat out, and they choose more packaged foods. In order to control the intake of sodium, besides controlling the intake of salt, they also reasonably choose condiments, packaged foods and snacks containing sodium.

In the past, our intervention measures to control oil and salt covering the whole city have made great achievements, but the intake of oil and salt for residents to eat at home is still higher than the recommended level. For future intervention and publicity, we will continue to strengthen the implementation of intervention measures to control oil and salt. On the other hand, we will also keep pace with the times, not only to continue to publicize the knowledge of reasonable nutrition for residents, but also with the popularity of residents eating out. Centralized dining halls, restaurants, take-away service providers, and prepackaged foods enterprises will also be the key targets for nutrition promotion in the future, advocating the supply of catering and food with "reducing salt, limiting oil and reducing blood sugar", encouraging dining places to carry out nutrition propaganda, formulating easy-to-understand nutrition labels in prepackaged foods, and guiding residents to choose food reasonably.

In addition, it is recommended that everyone eat at home, adhere to the habit of cooking at home with less oil and salt, and at the same time, eating at home also promotes the emotional exchange and promotion of family members.

6. Insufficient calcium intake is common, and residents drink less milk every day. It is suggested that residents increase the frequency of drinking milk and increase the intake of soybeans and bean products.

Our traditional Chinese diet is mainly based on plant food, which is conducive to the prevention of chronic diseases, but it also has an obvious defect, lacking a good source of calcium. Milk is a good source of calcium, and Chinese diet does not contain milk. A good phenomenon found in this monitoring is that residents have the habit of drinking milk, 41.6% residents consume milk every day, and 71.4% students consume milk every day. However, 86.8% residents still have insufficient calcium intake. Milk supplements the calcium that is insufficient in daily diet. Calcium is an integral part of bones and teeth, and it is an important nutrient for physical growth and bone development. Calcium deficiency will affect normal growth and development and cause osteoporosis. The Dietary Guidelines for China Residents (2016 Edition) recommends that each person should take 800mg of calcium daily, and students in the growth stage need 1000-1200mg. Every 100ml of milk contains about 104mg of calcium. In addition to the calcium in daily diet, 300ml of milk is needed every day. At present, the monitoring results show that the daily milk intake is insufficient. The average daily milk intake of residents is 97ml, and that of primary and secondary school students is 150ml.

Encourage residents to increase the amount of milk they drink. If the single intake is small, they can increase the number of times they drink milk, improve the calcium intake level and ensure the normal demand of the body. People who are lactose intolerant can choose low lactose milk or yogurt. At the same time, soybeans or bean products are also a good source of calcium. The Dietary Guide for Residents in China recommends that they consume 25g soybeans or a considerable amount of bean products every day. At present, residents’ intake of soybeans and bean products is less than half of the recommended amount. It is suggested that residents increase their intake of soybeans or bean products.

Title: Branching can promote the formation of flower buds in cherry trees.
Text:

The purpose of cherry tree branch pulling in spring is to improve the overall illumination, ease the branch potential of the tree, increase the amount of short branches, promote the formation of flower buds, and prevent the fruiting parts from moving out. The time to pull branches is best completed after the sap flows and before germination. Pay attention when pulling branches, pull straight, and don’t bend into a bow.

Young trees must pay attention to the strength of pulling the main branches, which must be kept above 60 degrees, and the side branches should be pulled to 90 degrees, so that they are easy to branch out and become flowers after budding. The rope for pulling branches should be tied with soft plastic rope or cloth strips, and the binding parts should be adjusted frequently to avoid overflowing the trunk and causing glue to die the tree.
