John Goodenough (American, born in 1922)

Stanley Whittingham (American, born in 1941)

Akira Yoshino (Japan, born in 1948)

　　The 2019 Nobel Prize in Chemistry was awarded to American solid-state physicists John Goodenough, Stanley Whittingham and Japanese chemist Akira Yoshino in recognition of their contributions in the field of lithium batteries. The three scientists will share the prize of 9 million Swedish kronor (about 910 thousand US dollars) equally.

　　The reporter interviewed many professors from Nanjing University and Nanjing University of Technology. All the professors interviewed were unanimous: the three professors were well-deserved, especially the 97-year-old American solid-state physicist John Goodenough. "We all think that he should have won this award long ago."

　　He set a new record for the oldest person.

　　Haruki Murakami in the scientific community: 97 years old, working every day.

　　This year’s Nobel Prize in Chemistry, besides the winning project "People-friendly", another highlight is Goodenough, a 97-year-old award-winning scientist. Previously, this record was held by arthur ashe King, an American scientist who won the 2018 Nobel Prize in Physics at the age of 96. Because of Goodenough in the name (meaning "good enough"), Goodenough was also humorously called "good enough" by the outside world.

　　For many years in a row, the "good enough" old man has been nominated, but he has been in a state of running with him. "Everyone thinks that the old man should have won this award long ago." Zhu Jixin, a professor at the Institute of Advanced Materials of Nanjing University of Technology, said that Goodenough has been nominated for the Nobel Prize many times, which is almost the "Haruki Murakami" in the scientific circle.

　　Previously, Goodenough has made outstanding contributions in the field of magnetic materials. For him at that time, electrochemistry belonged to the nature of "playing with tickets". "Early batteries had low discharge capacity and energy storage density. Goodenough found lithium cobaltate with layered structure as the anode of the battery, and used metal materials other than lithium as the anode, which can realize high-density energy storage. " In this way, rechargeable lithium batteries can be commercialized.

　　Now, the "good enough" old man who is over 90 years old still goes to work in the small office of the University of Texas at Austin every day. To this, he explained, "My work is not finished yet."

　　"Good enough" in Professor Nanjing’s eyes: All-rounder in arts and sciences with high output, especially loving home.

　　Many professors interviewed by this reporter are no strangers to Goodenough. Professor Jin Zhong from the School of Chemistry and Chemical Engineering of Nanjing University told the reporter that Mr. Good enough is still studying new energy storage battery systems, especially high-safety solid-state lithium batteries, which maintain high-quality scientific research output every year. At some meetings, there is no lack of him. "He is very kind and approachable. He has many new ideas and has been breaking through himself. When he speaks the report, the organization is very clear. The articles he writes not only put forward new concepts, but also explain the principles very clearly. " Admiralty said that he has also taught a group of masters of making batteries, and his disciples are all in academia and industry.

　　In academic circles, Goodenough’s "all-rounder" is also famous. From philosophy and other liberal arts disciplines to lithium battery research and other fields of science and engineering, Goodenough’s learning and scientific research stories across the liberal arts and sciences have become the benchmark for future generations to marvel at. Professor Zhou Haoshen from the Department of Energy, School of Modern Engineering and Applied Science, Nanjing University, told the reporter that Goodenough was still a "special family lover" and his life was very warm.

　　prize motivation

　　They make the use of lithium batteries "good enough"

　　"The Nobel Prize in Chemistry was awarded to three scientists, which gave a shot in the arm to the new energy field that has not won awards for many years." Professor Jin Zhong of Nanda University said that the Nobel Prize in Chemistry has been awarded to research in biochemistry and other fields for two consecutive years. This time, Mr. "Good enough" won the prize at the age of 97, which can be said to be widely expected. The award-winning research on lithium-ion batteries is a systematic research with traditional electrochemistry as the core and involving physics, chemistry, energy and materials.

　　A Professor Hao Shen from Nanda Zhou introduced that the early nickel-cadmium batteries and lead-acid batteries had low energy density. In 1970s, Stanley Whittingham, one of the winners of the 2019 Nobel Prize, made the world’s first new lithium-ion battery with titanium sulfide as the cathode material and lithium metal as the cathode material.

　　B This is undoubtedly a great progress of mobile power supply, but it has a lot of hidden dangers, because lithium metal is active, so the battery will be in danger of explosion. In order to solve this problem, Goodenough predicted that if the positive electrode was made of a metal oxide containing lithium instead of a metal sulfide, the battery would have a greater potential. In 1980, Goodenough invented the most important component in lithium batteries, lithium cobaltate cathode material. Nowadays, most portable electronic devices all over the world use this cathode material.

　　C Since then, Japanese scientist Akira Yoshino has discovered that the negative electrode can be made of carbon material and does not contain any metal. Matching the positive electrode discovered by Goodenough, he invented the first commercially feasible lithium-ion battery in 1990. Instead of using metallic lithium as the cathode, he used graphite, a carbon material that can insert lithium ions like lithium cobaltate as the cathode.

　　In 1991, the lithium-ion battery jointly invented by Akira Yoshino and Goodenough was put on the market by Sony, which marked the large-scale use of lithium-ion batteries. The original brick-like "mobile phone" no longer exists, and it is replaced by a thin mobile phone that uses lithium batteries and "slim down" the parts together.

　　At present, both electric vehicle technology and mobile electronic technology are based on the vigorous development of lithium batteries, which makes our life "good enough".

　　How to solve the problem of battery spontaneous combustion and slow charging?

　　"Super Battery" is on its way.

　　The cooperation between Akira Yoshino and Goodenough has made the lithium battery with high explosion risk safe, but readers will surely ask, why do the news of spontaneous combustion or explosion of mobile phone batteries still occasionally appear in newspapers? Admiralty explained that the fire and burning accidents of mobile phones and electric vehicles will be reported every once in a while in the news, precisely because the safety of lithium batteries is still not satisfactory. It can be said that people are still not completely satisfied with the performance of lithium-ion batteries, and further technological innovation is needed to develop a battery with high energy density, good safety, long cycle life and no pollution to the environment, which is exactly what people are looking forward to.

　　In addition, our common "complaints" about the lack of fast charging and large capacity of lithium batteries are also the future development direction of lithium batteries. Zhou Haoshen said that the "technological revolution" of lithium batteries is still on the road, and there are three main innovations: the energy density, power density and safety factor of batteries should be made higher. But there is a problem that you can’t have your cake and eat it. Therefore, Goodenough, a 97-year-old "good enough" old man, still insists on the front line of scientific research, just to solve these problems. Perhaps in the future, "super battery" will be successfully born, and new electrons with high energy density, such as lithium air battery, metal battery and lithium sulfur battery, will better change our lives.

　　A doctor from NTU has just become a "good enough" postdoctoral fellow.

　　In Nanjing University Institute of Technology, Zhou Haoshen’s lithium battery research group specializes in the research of new electrochemical energy storage materials and technologies, including lithium-ion batteries, and keeps in communication with Goodenough’s research group.

　　The reporter learned that a doctor who graduated from Nantah Institute of Technology also successfully applied for a postdoctoral position in Goodenough’s research group, officially went to the United States in September this year and began to follow Professor Goodenough as a postdoctoral position. Professor Zhou Haoshen revealed, "Yesterday, the postdoctoral fellow was still with ‘ Good enough ’ The old man discussed the work of NTU solid lithium air battery and agreed to cooperate.

CCTV News:Do you know how many Internet accounts are associated with your mobile phone number? Has your mobile phone number been registered as an Internet account by others? What should I do if I find someone else has registered an Internet account with their mobile phone number? Today (July 21st), the Ministry of Industry and Information Technology officially upgraded the "one-card universal access" system to version 2.0, which can provide users with the nationwide Internet account "one-card universal access" service.

"One-card universal inquiry 2.0" is a national Internet account convenient inquiry service launched by the anti-fraud center of the Ministry of Industry and Information Technology on the basis of the national mobile phone card "one-card universal inquiry" system, in conjunction with head Internet enterprises and telecom enterprises.

Users can inquire by filling in the mobile phone number, the last six digits of the ID number and the verification code through the inquiry portals such as "Industrial News Micro Report", "Anti-fraud Special Class of Ministry of Industry and Information Technology" and "China Xintongyuan". The query results are replied through the unified short message port within 48 hours.

　　　　　　 It is understood that in order to help crack down on telecommunication network fraud and solve the problem of users being "impersonated to run cards", the Network Security Administration of the Ministry of Industry and Information Technology launched the "one-card universal inquiry" service for national mobile phone cards in September last year. Users can check the number of mobile phone cards under their own names and cancel their accounts in time for abnormal number cards, which can effectively reduce the space for criminals to open and sell cards illegally. According to statistics, at present, more than 85% of fraud cases are carried out through the Internet, and many of them use Internet accounts registered by other people’s mobile phone numbers to carry out fraud activities. In order to prevent the risk of fraud related to Internet accounts associated with mobile phone numbers, the Ministry of Industry and Information Technology upgraded the original mobile phone number "one certificate for universal access" to mobile phone+Internet account "one certificate for universal access".

At present, the "one-card universal inquiry" system has opened up the relevant systems of 93 provincial-level basic telecommunications enterprises and 39 mobile communication resale enterprises in China. As long as I have a domestic mobile phone card under my name, I can use the inquiry service.

Wei Liang, Vice President of China Information and Communication Research Institute:In order to protect users’ personal information security, we use desensitization display, transmission line, data encryption, digital certificate and other mechanisms to ensure security, and authenticate the information submitted by users, so as to ensure that only the telephone number under the user’s own name can be queried in association with the registered Internet account.

Wei Liang said that the Anti-Fraud Center of the Ministry of Industry and Information Technology has guided Internet companies to establish supporting service mechanisms such as account details inquiry and account unbinding disposal, and Internet companies will handle any objections or complaints raised by users as soon as possible. Follow-up will combine the anti-fraud work situation, connect more Internet companies according to factors such as user scale and fraud risk, and support a wider range of Internet application queries. And launched the "one-click unbinding of secondary number" service to realize one-click unbinding of the Internet account association bound by the number before I hold the mobile phone number.

Sui Jing, Director of Network Security Administration of Ministry of Industry and Information Technology:In the next step, we are now actively docking with some commonly used ones, such as Sina Weibo, 58 City and so on … … Gradually increase the number of Internet companies accessing the platform, and we also welcome the vast number of Internet companies to join our queue.

　　What are the specifications, dimensions and uses of common battery models (No.1, No.2, No.5 and No.7)? Due to the limitation of conditions, only a few existing batteries have been roughly measured and confirmed. The logos such as AAA, AA, C, D, N, F, SC, etc. seen on the battery body are all American model logos. In China, except for a few by number, others seem to adopt the American naming method, but in other countries such as Japan, the names may be different.

　　[Battery model] Introduction of common battery models Detailed description of common battery sizes and specifications

　　1. Correspondence of common battery models and sizes

　　In the following table, 1-4 are all commonly used in our life, while 5-9 are rarely used or paid attention to. For example, A, SC, N and F are mostly used in rechargeable battery packs, and they are often wrapped in skins, so it is impossible to directly see the battery models, but not all of them.

　　Second, the common battery diagram and use

　　1. AAA battery (No.7 battery)

　　AAA battery is commonly known as No.7 battery, which is a little smaller than No.5 battery. It is mostly used in remote control and other places where the volume is limited but the power consumption is not too large. Flashlights are also used, but most of them are used in combination. No.7 battery size: height 44.0mm, diameter 10.0mm.

　　2. AA battery (No.5 battery)

　　AA battery is also called No.5 battery, which is the most common one. Electric shavers, electronic toys, digital equipment, etc. are used the most. Many AA rechargeable batteries are also used as battery packs, especially the 4.8V rechargeable four-section combination on toys. Size of 5th battery: height 49.0mm, diameter 14.0mm.

　　3. Type C battery (No.2 battery)

　　Type C battery is also called No.2 battery, which is a little smaller than No.1 battery and is often used in flashlights and audio-visual equipment. Size of No.2 battery: height 49.5mm, diameter 25.3mm.

　　4. Type D battery (No.1 battery)

　　D-type battery is also called No.1 battery, which is the same as No.5 battery. It can be used in many occasions, such as electronic lighting equipment, flashlights and so on. Size of No.1 battery: height 59.0mm, diameter 32.3mm.

　　5. AAAA battery

　　AAAA batteries are mostly used in some high-end electronic devices, such as Bluetooth headsets. AAAA battery size: height 41.5mm, diameter 8.1 mm..

　　6. Type A battery

　　Type A batteries are mostly flat-headed batteries, which are generally used as battery packs. When lucky chance searched for pictures of such batteries on Google, it seems that almost all of them are flat-headed batteries. The height of Type A batteries is similar to that of No.2 batteries, with a slightly smaller diameter. The battery size is 49.0mm in height and 16.8mm in diameter.

　　7. SC battery

　　SC battery is also generally used for stacking battery packs, which seems to have never been seen before. The battery size is 42.0mm in height and 22.1mm in diameter.

　　8. N type battery

　　N-type battery is also generally used as a battery pack. Because of its small size, it will also be used in electronic devices with limited volume, such as doorbells. The battery size is 28.5mm in height and 11.7mm in diameter.

　　9. Type F battery

　　F-type batteries are also used in battery packs. See the battery body for the F-type logo. The battery size: 89.0mm in height and 32.3mm in diameter.

　　There are also small square or cylindrical batteries such as 23A(12V), 27A(12V), 10A(9V), 25A(9V), 6F22(9V), F22(6V), 11A(6V), 26A(6V), 476A(6V) and 2X625A(3V). The actual voltage is about 10V. In the evening, I took the 6F22 apart and looked at it. There are six "cake" batteries stacked inside (it is easy to separate them with blades and the filler is easy to pick up), and then the outside is covered with a layer of plastic and then encapsulated with aluminum skin.

Lazy and greedy, do not love labor, only love movies.　

Last weekend, two hardcore movies were discussed by everyone.

One is Wei Jiahui+Liu Qingyun’s hot police and bandit suspense film Detective Wars, and the other is the annual Chinese-language horror film Curse that many fans are looking forward to.

"Curse" is a very lively movie both inside and outside the play. It is adapted from the true story of a six-mouth evil in Kaohsiung. The trailer was taken off the platform because it was too scary.

When it was shown in Taiwan Province, China, some viewers fled the cinema in fear, and some went to the temple to worship God after watching it. In the same period, the box office topped the Hollywood blockbuster "New Batman", ranking first at the box office of Taiwan Film this year with a score of NT$ 170 million.

With such a stunt, the appetite of mainland fans is naturally lifted high, and even known as "the best Chinese horror film of the year."

However, after the "curse" was launched, it was scolded by the hot search.

Not for anything else, just because of "bad luck."

Is "The Curse" really horrible or unlucky? Xiaowan has helped everyone to check the film. The front part is "high energy" and timid.

"Curse" strung together a curse spanning six years with two timelines.

Six years ago, if a man and his boyfriend and friends formed a "ghost squad" to explore the mysterious village. The whole village is wrapped in a strange and mysterious atmosphere. Everyone greets with strange gestures and worships strange evil spirits.

Boyfriends and friends broke into the "absolutely forbidden tunnel" and died on the spot, and the villagers also died. If the pregnant man was lucky enough to survive, he left here in a state of mental breakdown.

Six years later, Ruonan, who returned to normal, got her daughter’s right to care, and the mother and daughter started a new life. But strange things have happened one after another, and my daughter has symptoms of evil.

If the man runs around for his daughter, but more innocent people suffer, she finally decides to go back to the source of fear-the tunnel in the forbidden area of cults to find out.

On the surface, the horror elements in The Curse are nothing new, but a combination of "Death in a Forbidden Area", "Curse-ridden" and "Strange Death", with the tearful affection elements of "Motherly Saving Women".

But is the "Curse" really about the story of "the great mother is eager to love her daughter and return to the forbidden area PK evil spirit"?

Not necessarily.

There are many contradictory scenes and details in the film. The biggest doubt is: When did the man know about the evil god The Secret Behind? Six years ago or six years later?　

We can interpret this film in a different way, which may break the existing story about "maternal love".

Formally, The Curse also belongs to the popular screen/desktop movie in recent years, which is constantly switching between mobile phone screen, computer screen and video recording in the monitoring room.

Most of the curse content is if the man is explaining it to the screen, and this first-person narrative is actually mixed with many subjective elements.

Through the screen, we saw a novice mother who often "does bad things with good intentions", and she unconsciously felt sympathy and pity.

But what if the man lied? What if we see what she wants us to see?

What if it was all a scam from beginning to end?

The Curse has both positive and negative interpretation space. It depends on the audience’s understanding that loving mother/evil mother, saving women/sacrificing, breaking spells/unsealing evil spirits.

As early as the beginning of the film, "The Curse" implied by the running direction of the Ferris wheel and subway that "our thoughts quietly shape the world". The world is what you think.

The biggest controversy surrounding the curse is: bad luck.

Why did the audience feel unlucky, and even this topic was once hotly searched.

The first is the immersive fear brought by Chinese horror.

Japanese, Korean, European and American horror films are still separated by a layer, and ghosts that can only be hit by crossing the ocean cannot induce the sense of sight of domestic audiences. Taiwan Province horror movies are different. Everyone has the same root and the folk culture looks familiar.

There are two kinds of horror elements in the curse: foreign elements and Chinese elements. The former includes insects, antennae, secret fear and jumpscar; The latter includes folk customs, feudal superstitions and Chinese binding.

Although the former is scary, it will be forgotten after seeing nausea; It is the latter that really goes deep into the bone marrow and causes association.

Whispering the mantra "Fire Buddha Xiu Yi" and "Heart Sa Baa" which can be seen everywhere, strange cult totems can also find similarities in murals;

There are common spells and exorcism rituals in feudal times; There are also ancient altar offerings, swaying dim red lanterns, and hairy clay dolls in the ancestral hall, which can understand the essence of Chinese horror.

Have to sigh with emotion, Taiwan Province horror movies have a way of holding Chinese horror. It is a trend in recent years to combine folk elements with stories of evil spirits, and it is also an opportunity for Taiwan Province horror films to revive. The previous "Little Girl in Red" series and "Zongxie" also exploded for similar reasons.

The second reason for bad luck is that the audience feels offended.

Watching traditional horror movies, we usually stand in the perspective of God and overlook the tricks of the characters in the film. Although the people in the film have no idea about their own situation, we know in advance that there are ghosts of the dead, and we treat them with a sense of superiority from an omniscient perspective.

"Curse" uses screen narration, which is equivalent to the audience standing in the second perspective and having an equal dialogue with the characters in the film, which is easy to produce immersion.

So when we read the spell after Ruonan at the end of the film, we found ourselves cheated and became a part of the curse.

When the audience realizes it, people will naturally feel annoyed. The subtext is "The director actually dragged us into it" and "The dummy actually lied to the real person".

This kind of "offense" to the audience is not new, and it has also appeared in other horror films before.

The most classic is the video of Sadako’s death in "The Ring of Midnight". People who watch the video will die strangely within 7 days, and if they pass it on to others, they can hand over bad luck.

There are also pirated videos in "Ghost Will Show". It is said that anyone who sees the death of Fusang (the film in the film) will be killed by a female ghost. Of course, the characters in the play saw it, and so did the audience outside the play.

In Truth or Adventure, there are also scenes in which videos are posted to video websites. In this way, the protagonist group allows more people to share the devil’s sanctions.

"Curse" should refer to the above films and set up a bridge that offends the audience. From the perspective of communication, this stunt is quite memorable, which is really conducive to the wide spread of the film.

Its essence is no different from old terrier’s "If you don’t forward it to X people within X hours, you will …", so you don’t have to feel unlucky or unlucky.

Don’t be afraid, there is also a curse letter in Legend of Wulin.

Returning to the film itself, The Curse is a Chinese horror film worth watching with acceptable quality.

The greatest advantages and disadvantages of The Curse are related to the screen narration.

On the one hand, with the help of large and small screens, it builds a horror experience with a strong sense of immersion and interaction, and all the scary pictures seem to happen in front of us.

On the other hand, in order to pursue the consistency of the form before and after, the film also added a screen where it is not necessary to use the screen narrative, which is not as good as the semi-screen narrative of the Female Ghost Bridge.

The Curse has brought many amazing highlights, but there is still a lot of room for improvement. Kevin Ko, a new generation director, also has ambitions and plans to devote himself to it.

When he was a student, he filmed a small-budget horror short film "Ghost Print", the first feature film was the slashing thriller "Fatal Party", and in his early works, there was a doomsday counterattack related to the doomsday element, which was enough to see his interest.

In the past ten years, he has not produced much, and he is out of the category of horror. The Adult 2, the Emergency of Getting Off the Bill and the Budaoxia, which were filmed in the mainland, can only be regarded as unsuccessful commercial comedies.

From the beginning of "The Curse", Kevin Ko returned to the old line of horror films. The win-win box office reputation of "Curse" gives him confidence to promote the follow-up films of the same type.

In addition to Curse 2, which features a girl and a boy, Kevin Ko also intends to open a "one-word movie universe" based on the real events in Taiwan Province.

Maybe, there will be the next explosion in the follow-up new films "Pickling", "Sleeping", "Even" and "Burial" of "One Word Movie Universe".

　　Data Map: On the third day of the first month in year of the loong, adults and children played "the games we played together in those years" at the Spring Festival Temple Fair in year of the loong, Xintiandi, Wuhan, playing marbles, kicking shuttlecock and rolling hoops. China News Agency issued ZhangChang photo

　　BEIJING, Beijing, 12 Jan (Shangguan Yun) "Drop, drop, drop the handkerchief, and gently put it behind the child. Don’t tell him, hurry up and catch him, hurry up and catch him … …” I believe that this children’s song has a place in many people’s memories. Twenty years back, in that era when the material conditions were not as rich as now, it was not one popular video game after another that occupied many people’s childhood memories, but a series of simple but memorable entertainment activities such as "finding friends", rubber-jumping and throwing sandbags.

　　For example, "turning the rope" is usually the cooperation of two people: a piece of thin rope is tied into a rope loop, put on two wrists or "put on the palm", and then woven into a pattern with fingers; The other deftly picked up the string with his fingers, connected the loop and turned it into another pattern. In this way, according to a certain routine, turn all the way down until it is turned back to its original state.

　　There are quite a lot of rope-twisting routines. Two people can play and one person can play. It is said that there are more than 2,000 patterns that can be summarized so far. However, there are only four or five styles that can be turned out by two partners: bridge, noodles … … Wang Xu, the author of the popular book At that time, recorded this kind of game in detail. He said that he could vaguely remember that the fishing net and noodles followed, from the crossed fishing net in one hand to two parallel noodles in the other’s hand, which was very vivid. "And ‘ Take a bath ’ In fact, it is an empty circle — — It turned into a bath basin, and it was soaked in soup, so I had to start all over again. "

　　"It’s not just rope climbing. When we were young, there were all kinds of fun games such as hopscotch, throwing sandbags and origami." After 90, Huang Xiaofei still remembers that girls like to play bungee jumping together in primary school. Basically, four or six people play together and are divided into two groups. One group puts on the rubber band and the other group jumps. According to the rules of the game, the jumping party loses and then replaces each other. "If you hook the rubber band, you lose. This game especially tests dexterity, sometimes ‘ Addiction ’ Come up, two people can also play, and the other end is tied to the tree. "

　　Besides bungee jumping, Li Jing, a post-90s girl, liked and often played the game of "playing glass ball" when she was a child. "Strictly speaking, boys played glass ball more than girls, so I was quite different at that time".

　　How to play "playing glass ball" Li Jing said, we should first dig a hole of moderate size on the ground, which should not be too wide or too narrow. Most of them are stuck with the diameter of the glass ball, which makes it a little difficult. "There are not too many people, and there are several different types of play. The simple thing is to draw a line away from the dug hole and bounce the glass ball in outside the line to win, which is a bit like golf; Later, it was developed to be able to bounce someone else’s glass ball into a small hole, which also counted as winning the other party. "

　　"At that time, in order to play, I collected a lot of glass balls and took money to buy them in a small store. I remember that there were one dime and one dime. Unfortunately, the technology was not pure enough, and it was not long before I was won by other little boys." Speaking of the past, Li Jing couldn’t stop smiling. "There are many types of glass balls, some of which will be embedded with patterns, which are particularly beautiful. Then I won’t be willing to take them out for the competition, and I will quietly collect them."

　　In fact, in addition to jumping rubber bands, turning ropes and playing glass balls, there are many fond memories of games in childhood, such as jumping houses, throwing sandbags, and a group of people competing to make hand-folded roses and paper crane … … Huang Xiaofei especially misses those games when she was a child. In her eyes, they are not just games, but also memories intertwined by many people of different ages. "We miss not only those games that look simple now, but a feeling and miss the quiet time in the past."

　　Wang Xu has a similar feeling. He said that the original choice to record these games was to express a feeling of nostalgia for childhood. "The most emotional games are not necessarily the most fun games, but games like soap bubbles, rope turning and handkerchief throwing that reflect childhood innocence and warm friendship between children."

　　"Most of the children don’t play these games now. If you only look at it from the perspective of playing, it may be far less interesting than what they are playing now. " Wang Xu does not deny that some of the previous games have become "outdated", but he feels that the individuality and creativity, closeness to nature and the face-to-face interaction between children in these games have all been lost. "This is a pity for the children." (Some interviewees in this article are pseudonyms) (End)
