Don’t hesitate to call 120 at this time!

    The second Saturday of September every year is the World First Aid Day, which aims to publicize and popularize the knowledge and skills of emergency rescue and improve the public’s self-help ability. This year is the 24th World First Aid Day. Let’s talk about what we should call "120" and what we should pay attention to.

   What situations do you need to call 120?

    What would you do if we suddenly suffered an accidental injury or a friend around us suddenly fainted? You may answer, call "120" emergency number. This answer is not entirely correct. The 120 hotline, also known as the "life hotline", is like a life-saving straw. Behind every emergency call, there is a life that needs help. But what needs to be understood is that not all unexpected situations need to call 120, and the "life hotline" should be left to those who really need emergency assistance.

    So, what circumstances need to call 120 emergency number? If you are outside the hospital, such as at home, in public places, or in the wild, once you have a sudden critical illness such as heart disease and stroke; Serious injuries caused by car accidents and accidental injuries; Fire, drowning, electric shock, poisoning, trampling and other sudden disasters; When there are major problems in life and health due to various unexpected factors, you should immediately call 120 for help.

   What are the symptoms of sudden critical illness?

    Let’s talk in detail about what symptoms may be sudden critical illness. If you encounter the following situations, don’t hesitate to call 120 for first aid immediately.

    1. If sudden severe chest pain, palpitation, dyspnea, fainting, accompanied by sweating and other symptoms, you should suspect a heart attack.

    2. In case of sudden hemiplegia, skewed mouth, confusion, difficulty in speaking or understanding, difficulty in seeing things with one eye or both eyes, severe headache, syncope, etc., you need to be alert to cerebrovascular accidents.

    3. The patient is pale, sweating profusely, with a fast but weak pulse and decreased blood pressure, which may be shock or collapse.

    4. A large number of hemoptysis or hematemesis also indicate that a critical illness may suddenly occur.

   What details should I pay attention to when dialing 120?

    The "120" emergency call is the first signal and premise to start rescuing critical patients. Invalid calls will seriously affect the normal work of the command center, delay the rescue time and waste emergency resources. In the process of making a phone call, you should also pay attention to the following six points to avoid delaying the treatment time.

    1. When dialing 120, you should try to stay calm, don’t panic, and speak clearly and concisely.

    2. Make clear the patient’s symptoms or injuries, so as to send a car accurately, and also make clear the site location, waiting place and contact telephone number that can be connected, so as to facilitate contact.

    3. After dialing 120, you can arrange people to wait for the bus at the intersection or next to obvious signs, and wave when you see the ambulance, so as to save time.

    4. If people from other places in Beijing are not familiar with their location, they should ask local people for help or call for help on their behalf.

    5. If you are at the junction of two counties and cities, the mobile phone signal is prone to drift, which can be avoided by using a fixed telephone. If there is no condition, you can also ask the emergency center where the signal drift is received to call for help.

    6. When dialing 120 on the expressway, it is necessary to explain the direction and general orientation. There is a kilometer sign on the shoulder, and the expressway code and kilometers should be clearly stated.

    It should be noted that dialing 120 is generally not allowed to specify a hospital. The 120 Command and Dispatch Center uniformly allocates the city’s emergency resources, and handles emergency patients in different levels and districts. First, hospitals are allocated according to the principles of being nearby, being urgent and professional, so as to ensure that patients can be treated quickly.

    In addition, it should be understood that there is a charge for calling an ambulance, which generally includes two parts: ambulance fee and pre-hospital first aid fee. Of course, these fees are uniformly stipulated by local provinces and cities, and all fees are based on standards. You don’t have to worry about the inflated fees.

Baojun responded： Yue is not a brake failure, but a ＂brake assist downgrade＂!

In the process of using the car, if the car can’t be braked, then the user will understand that this is "brake failure". Because the user is not an automotive R&D engineer.

Recently, due to the problem of Bao Junyue’s braking system, some users’ braking failure and braking force weakened, and some car owners had traffic accidents and even dared not drive. Faced with this situation, Baojun officially responded at the first time. In the statement issued by Baojun, users are informed that Yue is not a brake failure, but a "brake assist degradation".

[1] "Brake failure" and "brake assist degradation" mean the same thing to users!

As mentioned earlier, when the owner stepped on the brakes, but the braking force was insufficient, it was "brake failure" from the user’s point of view, because the user was not an automobile engineer. Therefore, the officially declared "brake assist degradation" is actually the same as "brake failure" in the eyes of users. Simply put, there is something wrong with the braking system.

Since there is a problem, it must be solved! In Baojun’s statement, he did not point out the specific solution, but said in general terms that "the user’s vehicle problem has been solved, please feel free to use it" and "sincerely and properly cooperate with the owner’s aftermath". These two sentences are both general.

First, it didn’t explain exactly how it was solved. After the software update, will there be similar situations in the future? How to prevent similar situations from happening? Baojun didn’t make it clear.

Second, Bao Jun did not specifically point out what solutions there are. Is it compensation amount or compensation maintenance? Or what? I didn’t make it clear. Therefore, from the user’s point of view, after reading Baojun’s statement, I don’t know what to do.

[2] The problem of the car is easy to solve, and the psychological fear of the user takes time!

If you can’t stop while driving, you will be very scared. Even if it is repaired, I believe you will still be afraid to continue driving for a long time. This is better than the recent Jeju Air plane accident in South Korea. Many people canceled their travel plans because they were afraid to fly again in a short time. Even if this is a small probability event, even if the entire aviation industry is still safe. However, consumers’ psychology has developed fear and needs time to repair.

By the same token, many Yueye users have suffered from "brake power degradation" this time, even if Baojun has explained that the problem has been solved, please feel free to use it. However, I believe that there will still be users who are afraid to drive again, or when driving again, the speed is slower. The problem of the car is easy to solve, but the psychological fear of the user takes time to repair.

[3] Baojun should take a complete recall process, not a paper statement!

Since the psychological fear of users is difficult to solve in a short time, it is necessary to build confidence in users! The correct way is not to solve it internally. Instead, take a complete recall process!

The formal recall process is to report to the State Administration of Market Supervision! Then submit the original design scheme, with a detailed explanation of the problems, causes and accident probability. Baojun needs to make a recall plan, which contains solutions to the problems found and ensures that the solutions are objective and effective. This plan also needs to be submitted to the National Development and Reform Commission and filed with the competent authorities. Recall under the supervision of the competent department or through OTA upgrade!

Only in this way can the problem be solved under the supervision of the relevant state departments. In the eyes of users, it is the real solution. The user’s inner fear will also be repaired. Now, relying on Baojun’s simple statement is not enough to calm users’ inner fears. On the contrary, it will deepen users’ distrust of Baojun!

Shenzhen has completed 17 million doses of vaccination, and increased the supply of vaccine to ensure that people should receive it.

　　CCTV News:In Shenzhen, Guangdong Province, the supply of vaccines has also been increased recently, and the vaccination coverage has been expanded to ensure that qualified people can receive all vaccines.

　　In the early morning of June 13th, more than 600 doses of COVID-19 vaccine were sent to a COVID-19 vaccination site in Futian District, Shenzhen, and the vaccination staff operated the cold chain overnight to extend the vaccination time and ensure the vaccine supply. In the case of large-scale supply of vaccines, the vaccines distributed to the inoculation points should be "cleared every other day".

　　In order to expand the coverage of vaccination, Shenzhen has added 603 temporary vaccination sites and 2,473 vaccination stations, relying on hospitals, community health centers and stadiums. At the inoculation point of Nanshan Cultural and Sports Center, the citizens who came to vaccinate according to the appointment time lined up in an orderly manner. At present, the maximum daily vaccination amount of this inoculation point is 5,000 doses. At the same time, according to the number of batches of vaccines in stock and the queuing situation at the vaccination site, the Shenzhen Municipal Disease Control Department adjusted the appointment method in time. From June 1, the city implemented the appointment vaccination work, which greatly shortened the waiting time of citizens at the vaccination site.

　　In the streets, communities, staff and residents of Yantian, Baoan, Longhua and other districts in Shenzhen, they joined the vaccination work. The layout of the inoculation site is well-defined, so as to avoid cross-trip of citizens as much as possible. Residents scan the code for filing, inoculation and observation, which is orderly. Since May, more than 2,200 volunteers have participated in the prevention and treatment work in Shenzhen.

　　It is understood that at present, Shenzhen has completed about 17 million doses of vaccination, with an average daily vaccination of about 500,000 doses and a maximum of 600,000 doses.

Scientific Anti-epidemic ｜ ＂Cheap Mobile Supermarket＂ trucks enter the community and the people live in an orderly way at home.

　　CCTV News:Since the outbreak of this epidemic in Changzhou, Jiangsu Province, several communities have been temporarily closed for management. People in the community live orderly at home, and many people cheer for epidemic prevention in different ways; Relevant departments drove the "cheap mobile supermarket" truck into the community to facilitate residents to purchase living materials.

　　These round pyrography works in front of us are the appearance of anti-epidemic personnel fighting in the front line, which makes people feel warm and powerful. After the outbreak of this epidemic, Mr. Fan, who lives in Heping International Garden in Tianning District, Changzhou, picked up a pen in his hand and created more than ten such pyrography.

　　Another resident, Ma Zhiming, who lives in Daming Jiayuan, Jiaze Town, Wujin District, is 70 years old. In the past two days, he has just finished writing and performing an anti-epidemic drama "War and Epidemic", which was well received by everyone after being sent to the group.

　　There are nearly 3,000 residents in Daming Jiayuan. Although the residential area is temporarily closed for management, many residents in the residential area will not only take care of their families, but also decorate their courtyards and balconies with various bonsai and flowers, so that they can feel the smell of "all loves can’t be shut up" at home.

　　In order to ensure the normal life of residents, local people not only send more people to do daily epidemic prevention and disinfection work, but also drive "cheap mobile supermarket" trucks in the community, with fresh fruits and vegetables, aquatic products, grain and oil and other living materials lined up, and the on-site staff dressed in protective clothing introduced the daily dishes to the residents who came to purchase. The reporter observed at the scene that there are more than 25 kinds of dishes sold here, and the price is lower than the market price. The local caring enterprises also sent fresh fruits and vegetables to the residents in the closed control area and the control area.

Restoration of the leakage incident in Gulou District, Nanjing： the joint examination school mistakenly took the exam ahead of time, and the students passed the questions to the students and thought a

　　Nanjing Yuying Second Foreign Language School’s Explanation on School Time Errors in the Mid-term Survey of Grade Seven Mathematics and Related Joint Survey. The intersection of pictures in this article

　　On the morning of April 25th, Gulou District, Nanjing conducted the mid-term unified examination for Grade One (Grade Seven). Many candidates found that the math problem in front of them was exactly the same as the one published on the Internet the night before the off-campus training institution "Learn and Think".

　　How can the examination paper of the district unified examination be leaked in advance? How do social training institutions get test papers in advance? … … Many parents have strongly questioned that the Education Bureau of Gulou District in Nanjing has openly "endorsed" learning and thinking under the background that the education authorities at all levels have issued a document to strictly control off-campus training institutions.

　　After many interviews, The Paper (www.thepaper.cn) clarified the cause of this "leaking incident" that attracted much attention from the society: the famous school "Yuying Second Foreign School" in Liuhe District of Nanjing and the strongest education area in Nanjing — — After consultation, the Education Bureau of Gulou District decided to adopt the mid-term unified examination paper ordered by the education department of Gulou District, and agreed on the unified examination time. However, Yuying No.2 remembered the examination time wrong, and as a result, the examination was one day ahead of schedule. After the examination, some students from Yuying No.2 Foreign School took photos of the test paper and sent them to the teachers of social training institutions who "learn and think" for analysis and answer. Since then, the test paper has been shared among parents by the teachers who "learn and think", which led to the early disclosure of the mathematics test paper for the first unified examination in Gulou District.

　　On the evening of 25th, Wen Jun, president of Yuying No.2 Foreign Language School, apologized to all sectors of society through The Paper on behalf of the school. Wen Jun said that due to the mistakes in the organization of this examination, he sincerely apologized to the Gulou District Education Bureau and all the junior high school students, parents and schools in Gulou District for their adverse effects.

　　The Education Bureau of Gulou District of Nanjing confirmed to The Paper that the results of the Math Examination in Grade One of Junior High School with "leaking questions" will be cancelled, and "there will be proper arrangements next".

　　Learning and thinking: I don’t know if it’s a unified examination paper in Gulou District.

　　On the morning of the 25th, the schools in Gulou District conducted the mid-term examination of the seventh grade (Grade One) mathematics.

　　Parents of many students felt familiar when they saw the test paper: On the evening of 24th, they downloaded a "2018 Mid-term Mathematics Test Paper for Grade One (Part Two) of Yuying Foreign Middle School" in the "Parents’ Help" forum.

　　After comparing with the unified examination paper in Gulou District on the morning of 25th, the 26 questions in the whole volume are exactly the same. Why did "learning and thinking" get the test questions of the unified examination in Gulou District in advance?

　　On April 25th, the person in charge of public relations responded to The Paper, saying that on the afternoon of April 24th, a student gave the teacher the math test paper of the first phase of Yuying No.2 Foreign Middle School and asked for answers. After that, the teacher shared the test papers and answers with the parents.

　　"Seeing some good papers and questions, teachers usually share and guide them among parents." The person in charge said that after understanding, the teacher was "completely unaware" that this set of papers was the next day’s Gulou District Mathematics Unified Examination Paper.

　　The person in charge said that at noon on the 25th, after the mid-term exam in Gulou District was over, parents heard that the unified exam questions in Gulou District were the same as those shared by the teacher in the group the night before, and they felt "very nervous" and puzzled about learning and thinking, and deleted the relevant papers uploaded to the group in time.

　　On the afternoon of April 25th, the relevant person in charge of Xueersi Nanjing went to the Education Bureau of Gulou District for a report.

　　Xu Zhengquan, vice president of Yuying No.2 Foreign Language School, told The Paper that as a joint examination school in Gulou District, Yuying No.2 Foreign Language School misremembered the examination time of seventh grade mathematics. "It should be on the morning of 25th, and we took it on the afternoon of 24th".

　　Xu Zhengquan said that after the exam, according to the usual practice, the examinee’s answer sheet was collected, but the examination paper was not collected, so the examination questions were made public after the exam. "The school definitely didn’t take the initiative to give the examination paper for learning and thinking."

　　Some parents questioned whether there is any interest between Yuying Erwai and Nanjing Xueersi, which jointly organized the "Learning and Thinking Class".

　　Xu Zhengquan and Wen Jun, the president of Yuying No.2 Foreign Language School, said that the statement that Yuying No.2 Foreign Language School cooperated with learning and thinking was purely misinformation, and "we have no connection with any training institution".

　　According to the public reports, The Paper found that in 2016, a school called "Yuying Foreign School" had cooperated with Nanjing to run the "Learning and Thinking Class".

　　According to the staff of Xu Zhengquan and Yuying No.2 Foreign School Office, Yuying Foreign School and Yuying No.2 Foreign School are not the same school, and they are independent.

　　On the evening of 25th, Wen Jun, the president of Yuying No.2 Foreign Language School, made a detailed response to the The Paper reporter, saying that after the school investigation, due to negligence in work, the school had an exam in advance. After the exam, a student took photos of the exam questions and passed them to the teacher surnamed Zhang, who was learning and thinking, which led to the topic being made public.

　　On behalf of the school, Wen Jun issued an apology statement through The Paper: I sincerely apologize to the Gulou District Education Bureau and all the junior one students, parents and schools in Gulou District for the bad influence caused by the mistakes in the organization of this examination.

　　"This problem is entirely due to the mistakes of school staff. The school will seriously deal with the relevant staff according to the relevant work discipline. " Wen Jun said.

　　In response to questions from parents, is Yuying Erwai giving a "back pot" to the Gulou District Education Bureau? Wen Jun said that "there is no such speculation". "Our own mistakes are our own responsibility and have nothing to do with others. Our apology is responsible and sincere. "

　　Gulou District Education Bureau confirmed that the math test results will be cancelled.

　　On the evening of 25th, Chen Chunbao, secretary of the Education Working Committee of Gulou District Committee, told The Paper that the math test scores of Grade 7 (Grade 1) in this district would be cancelled. How to determine the results of this course next needs to be studied, but there will be a proper arrangement.

　　According to its introduction, the leaked test questions were not written by Yuying No.2 Foreign Language School, let alone by "learning and thinking", but by the education department for schools in Gulou District to adopt and organize examinations.

　　Chen Chunbao said that Yuying No.2 Foreign Language Institute has been conducting joint examinations with some schools in Gulou District for many years, and there have been no problems before. On the 25th, the Education Bureau of Gulou District has received a statement and an apology letter from Yu Ying Er, and the other party is sincere.

　　"Although this incident was a unilateral mistake of time by Yu Ying Erwai, it was also a wake-up call for us." Chen Chunbao said that the Gulou District Education Bureau will further strengthen management and communication to prevent such incidents from happening again.

　　Chen Chunbao said that after research, it was decided that from the perspective of being responsible for all students, the results of this seventh-grade mathematics midterm exam will be cancelled. Gulou District Education Bureau will communicate and coordinate with the school and make proper arrangements for the next step.

　　Chen Chunbao told the The Paper reporter that since the plan is still under study, it is still impossible to give a definitive answer on whether it will "retake the exam". If there are further arrangements, all parties will be informed in time.

　　According to its introduction, the only problem this time is the seventh grade mathematics examination paper, and there are no problems in other subjects.

Read the article and release the annual original IP list, and the ＂post-90 s＂ writers contribute more than half of the online reading income.

On the evening of June 3rd, the 6th Reading Original IP Festival was held in Shanghai. As the "wind vane of IP development", Shengdian announced the annual heavy original IP list, including annual theme works, annual overseas works, annual top ten male/female popular works, annual adaptation expectation works and many other projects.

According to Cheng Wu, CEO of Reading Group, vice president of Tencent Group and CEO of Tencent Pictures, the value of IP development lies in "making good stories endless". "While good stories are constantly emerging, they also enrich the connotation and extension through various forms such as video games".

The newly released "Xinhua Cultural Industry IP Index Report" shows that at present, China’s Internet native IP is rising, potential writers and high-quality works are constantly emerging, and at the same time, the concentration effect of online literature IP incubation is strengthened, injecting new vitality into industrial development. The data shows that the online literature writers are constantly injecting fresh blood, showing the characteristics of being younger and more diverse. The "Z generation" writers and readers have become the mainstay of the industry.

Nearly 80% of the new writers in the reading platform in 2020 are "post-95 s", and the "post-90 s" writers have contributed more than half of the online reading income. Among them, the post-90s writers, Eagles Eat Chickens and Little Langjun Selling Newspapers, respectively, set a new monthly ticket and subscription record for online literature in the past 20 years with their two works, The Robbery of All Ethnic Groups and Da Feng Da Geng Ren.

That night, "Da Feng Da Geng Ren" included the four titles of "Best Works of the Year", "Top Ten Men’s Frequencies of the Year", "Oriental Fantasy Works of the Year" and "Expected Works of Film and Television Adaptation of the Year" in one fell swoop, making it one of the most eye-catching works on the list. "The author integrates common routines and uses excellent characterization and plot structure skills to create tension between characters and story clues, which brings readers a relaxed and pleasant reading experience." Zheng Zhang, an associate professor at Tsinghua University School of Journalism and Communication, commented.

Ye Feiye, a platinum writer of Reading Group, won the title of "Best Writer of the Year" and "Talking Elbow" won the title of "Honorable Writer of the Year". Ye Feiye won the first place in the monthly ticket list for girls in the original literature billboard for four years in a row, and her works have more than 10 billion hits on the Internet, which has set a new record for the electronic daily sales of single works for many times. Her representative works include I like tomorrow, I share half of my room with you, I like you, I decide, and my husband takes it home. Last year, "Talking Elbow" once again refreshed the popularity of works with the same theme with "The First Sequence", which was collected by the National Library together with his book "The King forgives his life". The new book "Naming of the Night" has also set a record for refreshing the first payment according to the number of hours since it was put on the shelves.

At the same time, the younger readers have also brought a new atmosphere in the field of online writing. The 2021 annual conference of reading articles held on the same day revealed that 70% of the active users of reading articles’ apps are under the age of 30, and the secondary theme loved by young people has risen, and the proportion of light novels has increased by 370% in three years. Young readers are keen on interaction and comments. In 2020, the number of "This Chapter" readings was nearly 100 million, which contributed more than 32% to the improvement of users’ per capita reading time and 10% to the improvement of users’ payment rate.

"To build an influential and vital IP, the key lies in long-term development planning." Zou Zhengyu, head of the copyright business of Yuewen Group, said that Yuewen platform has launched a series of plans in terms of audio content, physical book publishing, animation adaptation and game development. "For example, the audio work of" Da Feng Da Geng Ren "was launched for two months, and the broadcast volume of the whole network broke 40 million; The broadcast volume of "Men Out of Xianmen" reached 3.5 billion, and the audio works of "Waifu" also formed a very strong IP linkage effect during the TV series. "

In addition, in terms of comics, it is expected that more than 100 works, such as "The Dragon Shepherd" and "Above the Dome", will be developed simultaneously this year, and the first batch of more than 30 web IP’s that cooperate with Quick Watch Comics are also being changed. In terms of animation, IP content covers six series: legendary story, future fantasy, urban superpower, youth adventure, super-burning competition and heart-pounding. Recently, more than 50 films are being developed, including Da Feng Da Geng Ren, The First Sequence, Starting from the Red Moon, Ghost Blowing Lights and Global Martial Arts. In terms of games, IP-authorized games such as Douluo Mainland, Ghost Blowing Lights, Master of Secrets and Biography of Immortals will also be launched one after another.

"Reading will also take measures such as creative encouragement, work support, adaptation recommendation, etc., and within three years, the number of newly signed writers under the age of 30 will double, the remuneration will double, and the new gods will double. By supporting new writers and young writers, the creative ecology will be further activated." Yang Chen, vice president and editor-in-chief of Reading Group, said.

How do children ＂charge for 5 minutes and talk for 2 hours＂

　　I remember the first time I saw the slogan "charge for 5 minutes and talk for 2 hours", I immediately thought of those children who were alive and kicking all day. They are almost tireless in playing. They will be noisy in scenic spots or playgrounds until all the electricity is consumed. Then, in their parents’ arms or in the back seat of the car, they are still drinking or talking one second and falling asleep the next.

　　Next, it may often take only an hour to rest, and they can "resurrect with blood" and continue to play wildly. The reason why the baby is so tired is also a great reason.

　　However, although we all know this feature of children, do you know the reasons behind it? Why is there so much energy in their small bodies?

　　Comparable to triathletes.

　　At present, the most famous research on the amazing potential of children in anti-fatigue is an experiment done by researchers at the University of clermont-ferrand: they recruited three groups of volunteers, each with 12 people, who were national male athletes engaged in triathlon, cycling or long-distance running; 12 boys with an average age of 10 and a half; And 12 ordinary adult men who rarely engage in strenuous exercise participated in the study.

　　These three groups of volunteers were asked by the researchers to do two sets of 7-second cycling sprints, and then pedal their bicycles as soon as possible for 30 seconds.

　　After exercise, the researchers compared the energy production of different groups of volunteers, including aerobic exercise and anaerobic exercise. Among them, anaerobic exercise does not consume oxygen, but will produce a lot of lactic acid, which will cause muscle fatigue.

　　After that, the researchers compared the recovery rate of heart rate, blood oxygen level and lactate clearance rate of different groups of volunteers after exercise. Finally, the researchers found that children are not easily exhausted by cycling, which is equivalent to the fatigue of professional athletes.

　　In fact, in all tests, children’s physiological function performance is better than that of untrained adults, and their physical strength recovery speed is faster than that of professional athletes.

　　Muscle structure has advantages.

　　Although the experimental results are surprising, this advantage of children’s undeveloped body is not accidental, it is the result of children’s special body structure.

　　Don’t treat children as miniature adults, they are all "Little Superman" — — As far as muscle composition is concerned, children’s muscles are composed of 70% red muscle fibers and 30% white muscle fibers, while in adults’ bodies, red and white muscles account for 50% respectively.

　　This particularity of muscle structure means two completely different energy production mechanisms. White muscle fibers are mainly supplied with energy through anaerobic, that is, creatine phosphate (a high-energy molecule) and sugar (glucose) are directly supplied with energy, which can make muscles release strong explosive force in a short time. In contrast, red muscle fibers are powered by aerobic respiration.

　　Red muscle contains a large number of "small factory" mitochondria, which can use more oxygen and make the production more efficient. Therefore, although it is inferior to white muscle in explosive power and strength, red muscle has stronger endurance.

　　If an adult still has a lot of red muscle fibers, it is mostly inherited or the result of high-intensity training. But children do not benefit from training, but are born to be comparable to endurance athletes.

　　Small body shape is more divided

　　Children’s infinite energy not only comes from their unique muscle structure, but also benefits from their small body shape, which makes them have an extremely fast oxygen supply speed before their height soars in adolescence, and can deliver oxygen to all motor muscles in a short time to provide energy in time.

　　"It’s like the difference between a mouse and an elephant. Mice are small in size and have high oxygen demand, mainly relying on aerobic energy supply system; Elephants that are huge and bulky rely on anaerobic energy supply systems. " Sebastian Ratel, the leader of the research project, said, "In small animals, it takes much shorter time to transport oxygen."

　　As for the recovery speed, the experiment shows that the recovery rate of heart rate in children’s group is 85%, that of athletes is 60%, and that of untrained adults is only 40%.

　　Researchers attribute this outstanding performance of children to a more effective acetylcholine inhibition mechanism — — This neurotransmitter can slow down the beating speed of the heart through the parasympathetic nervous system (controlling the autonomous operation of the body).

　　Children also have outstanding performance in removing metabolic waste from the body. You know, metabolic waste is the culprit that disturbs muscle contraction. The research team tested the content of lactic acid in the blood of the tester — — Lactic acid is a metabolite produced by muscle fatigue. The test results show that compared with endurance athletes, children’s lactic acid disappears faster, and ordinary adults are far behind in this respect.

　　"Lightning speed" is the wonder of researchers for children’s physical recovery ability. They analyzed that this may be because children are smaller and their muscles are closer to the oxygen-rich blood pumped by the heart, so they can use oxygen more effectively. Children’s extra energy comes from slow muscle fibers, which contract slowly, protecting children from being injured by excessive exercise.

　　No need to exercise deliberately.

　　Although the metabolic ability is not limited by body shape, children’s legs are not strong enough, coordination is insufficient, and the toughness repair ability of tendon system is weak, which leads to low body efficiency and limited mechanical movement ability. It is true that children’s quick recovery makes people feel never tired, but it is not the case when they exercise for a long time.

　　After children enter adolescence, their bodies gradually turn to rely on anaerobic system, which, like their adult parents, makes them tired easily and slows down their recovery. Therefore, before puberty comes, it is best to focus on cultivating their sports skills and action effectiveness through coordinated exercise and motor function exercise, so as to improve sports efficiency, rather than focusing on improving aerobic metabolism, because children’s aerobic metabolism efficiency is already very high.

　　Therefore, there is no need to deliberately do aerobic exercise in childhood. On the contrary, from adolescence, it is necessary to continuously improve the motor function and efficiency of the body. Since children’s bodies grow rapidly and have a brand-new body cognition after entering adolescence, it is necessary to focus on improving aerobic metabolism at this time to maintain the body’s rapid recovery ability, delay the onset of fatigue, and prevent diabetes, obesity, insulin resistance and cardiovascular diseases.

　　Mentality and sleep also help.

　　In addition to the characteristics of physiological function, children’s mentality is a model of "living in the present". They devote themselves wholeheartedly to the present activities, crying if they want to, smile happily, naive and carefree, while we adults bear all kinds of pressures and worries of life every day, and have a lot of depressed negative emotions, which is also a great consumption of physical vitality and energy.

　　Needless to say, children can generally get much more abundant sleep recovery time than adults. According to the statistics of national data, the average sleep time of children under 5 years old is 10 ~ 12 hours, which is beyond our adults’ reach. (brown squirrel)

　　At the beginning of school, Ms. Li, who lives in Jiangxia, Wuhan, "panicked". "The balance of the bank card is insufficient. When I checked the consumption flow, the 12,000 yuan in the card was all recharged by the children playing games to buy props."

　　Ms. Li’s child is a "online game fan" this year. During the summer vacation, children play online games to kill time and buy equipment in the online game mall through WeChat coin purse. Ms. Li knows nothing about this.

　　How do primary school students deal with APP in their leisure time? In the past few days, the reporter launched the "APP survey commonly used by primary school students in Wuhan" online and offline. As of 18: 00 on August 31, more than 600 valid questionnaires were collected, including 431 online surveys and 175 offline surveys. Statistics show that chatting, short videos and game apps have won a lot of "juvenile hearts".

　　Nearly 60% of primary school students have exclusive mobile phones or iPad.

　　According to this survey, 58.7% of primary school students have their own smart phones or iPads, and mobile phones or iPads have become "playmates" and "study companions" for many primary school students. 60.09% parents have time restrictions on their children’s use of electronic products such as mobile phones, 36.66% parents only allow their children to study, and only 3.25% parents have no restrictions on electronic products and can use them at any time.

　　It is noteworthy that in this survey, 56.15% of primary school students said that they used their mobile phones or iPads for less than one hour every day, 35.5% used their mobile phones or iPads for 1-3 hours, 6.03% used their mobile phones or iPads for 3-5 hours, and 2.32% used their mobile phones or iPads for more than 5 hours every day. Experts generally recommend that children use electronic products for no more than one hour every day.

　　Some primary school students said frankly.

　　"You can only break up with your mobile phone for one day at most."

　　In the survey "How long do you think you can live without your smartphone or iPad at most", 20.42% choose a day, 33.41% choose a week, 23.2% choose a month and 22.97% choose a year or more.

　　"You can only break up with your mobile phone for one day at most!" A 10-year-old boy named "Mark" told reporters that he has his own iPad. Besides online classes, he also downloaded many commonly used apps and online games, such as WeChat, homework help, Tik Tok, Snake and Cool Dog Music. Parents stipulate that you should not use the iPad for more than one hour every day, but it is not strictly enforced on weekends and summer vacations. After a summer vacation, he felt that his eyesight had declined, but he was afraid to tell his parents.

　　China Children’s Development Report (2019) released by China Children’s Center and Social Science Literature Publishing House on August 2019)— — Children’s life outside school shows that children spend an average of 43.24 minutes using electronic products every day on school days. It takes longer to use electronic products on weekends, with an average of 96.27 minutes.

　　Excessive use of electronic products is not conducive to children’s physical and mental health. A survey shows that the longer children use electronic products, the lower their social skills and anti-frustration scores, and the higher their myopia.

　　Chat, short video, game APP

　　Won the "juvenile heart"

　　In the "APP you use most often" option survey, 63.11% of the respondents checked "APP related to learning", accounting for the highest proportion. Followed by social apps such as QQ and WeChat, accounting for 61.72%; Short video apps such as Tik Tok and Aauto Quicker accounted for 37.82%, game apps such as the glory of the king accounted for 24.13%, and other apps accounted for 15.31%.

　　Children put learning-related apps in the first place when filling out the questionnaire, but when the reporter actually investigated and visited, it was found that the latter three types of apps were the most interesting and used by children: social, short videos and games. China Child Development Report (2019)— — The Situation of Children’s Life Outside School also shows that children’s liking for watching Tik Tok, cartoons and Aauto Quicker for entertainment (4.19 points), playing online games and chatting online (4.00 points) has reached or even exceeded 4 points (out of 5 points).

　　More than 30% of respondents occasionally brush short videos.

　　Regarding "Do you pay attention to Tik Tok, Aauto Quicker, Volcano, bilibili and other short video apps", 47.33% choose "I know but I’m not interested", 36.43% choose "I pay attention to it and brush it occasionally", 10.9% choose "I brush it often and find it very interesting" and 5.34% choose "I not only brush it, but also try to upload it myself".

　　It can be seen that short video has attracted more and more attention after the rapid development in recent years. The children interviewed all know short video apps such as Tik Tok and Aauto Quicker, and the proportion of using them for 1-3 hours every day has reached 15.55%.

　　"According to your observation, what types of short videos do peers around you like to brush? In a survey, pupils’ responses mainly focused on five aspects, among which "parody in life" accounted for 54.99%, "entertainment circle related to idols" accounted for 34.34%, and "game explanation tutorial" accounted for 36.19%. However, "related to learning and professional skills" accounted for 37.35%, and "related to natural and cultural landscapes" accounted for 23.2%.

　　In the item "Why did you start to brush short video apps", children said that they often saw them online, accounting for 33.41%; Secondly, "curious, take the initiative to use" accounted for 29.23%, "classmates often brush" accounted for 20.88%, and "parents often brush" accounted for 16.47%.

　　Zhou Lina, a teacher of ideological and political course in Chongren Road Primary School, said that there are more and more APP softwares, which are constantly updated. Many softwares are helpful for children’s learning, which stimulate students’ interest in learning through entertaining, and the game mode meets children’s curiosity. However, for teenagers and even adults, we should have self-control. Parents need to set an example in front of their children, not to let their children drift, and not to ignore communication with them. It is suggested that we can accompany our children to study and discuss together, control the use time reasonably, pay attention to scientific use of eyes and protect our eyesight. In addition, the home and school closely cooperate to check the APPs used by children. Any app that contains pornographic violence, online games, commercial advertisements and other content and links, or uses exam-oriented education to increase students’ academic burden should be uninstalled.

　　Luo Hongwen, the principal of Qipanjie Primary School in Wuchang District, believes that it is obviously unrealistic for new technologies to keep pouring in and affect students’ lives and blindly block them among children. To teach children to identify and use them reasonably, teachers and parents should also guide them in ways that children are willing to accept, thus effectively improving the quality of education.
