A "Strong Dialogue" between Human Wisdom and Artificial Intelligence —— CCTV’s science and technology challenge program "Wit is Extraordinary" will appear at the end of August.

Program recording site

  Cctv news(Reporter Liu Chunyan) Who is the "three-point king" with higher shooting percentage, Jeremy Lin, the superstar of the National Professional Basketball League, and the robotic arm controlled by sensors through the identification system? Can a drone equipped with a "brain" escape the smash of badminton player Bao Chunlai? In the first original scientific challenge program focusing on artificial intelligence in China, "Wit Beyond Man", a "strong dialogue" between human intelligence and artificial intelligence will be staged here, and the whole society will witness these processes and find the answer.

  The combination of science and art: four highlights

  On August 2nd, a news conference was held at the recording site of the phenomenal artificial intelligence program "Wit Beyond Man" co-sponsored by CCTV and China Academy of Sciences (hereinafter referred to as CAS) and jointly produced by CCTV Comprehensive Channel and Changjiang Culture. This is by far the largest TV science popularization project involving the most extensive AI field and the largest number of researchers. It will be premiered in the prime time of CCTV-1 at the end of August.

  "Smart" aims to awaken people’s scientific curiosity through experiential interaction, show the future with artificial intelligence scientific and technological achievements, explore the boundary between human and AI capabilities, and explore the possibility of the relationship between them.

  It changes the cold posture of popular science programs, combines the rigor and interest of science, and focuses on "four highlights": science and big coffee help each other, "the strongest human" all debut, AI’s unique tricks, and original dance beauty. Combine "four characteristics": scientific, rigorous, interesting and authoritative.

  Zhang Guofei, deputy director of CCTV’s comprehensive channel, said in his speech: "Science is serious, and art is romantic and imaginative. It is our dream to try to open the channel between science and art and combine them to make the world better."

  Create two camps of "Wit Witness" and "the strongest human"

  The program also strives to build two camps, namely "Wit Witness Group" and "the strongest human". "Wit Witness Group" integrates various perspectives from the scientific, media and social circles. At present, the team members include scientists such as Yao Qizhi, Zhang Jianwei and Xu Ying, a researcher of Beidou navigation system of Chinese Academy of Sciences, as well as Ke Jie, the youngest four-time champion in the history of Go in the world, a nine-stage Go player who has had a man-machine battle with AlphaGo, CCTV host Sa Beining and film actor Jiang Yiyan, etc. Everyone will ask questions from their own perspective based on their own experience and understanding.

  At the press conference, members of Wit Witness Group told their stories about science and technology.

  Zhang Jianwei, an academician of Hamburg Academy of Sciences and director of the Cognitive Center of Shenzhen Advanced Institute of Chinese Academy of Sciences, said: "With the development of artificial intelligence, we have achieved breakthroughs in game and recognition of artificial intelligence by using big data, but the distance of artificial intelligence in the physical world plus sensing and decision-making still has a long way to go. Through this program form, people can realize the development prospects of artificial intelligence and how far the combination of the physical world is."

  Xu Ying, a researcher of Beidou Navigation System of Chinese Academy of Sciences, said that he came to the program hoping to see the reconciliation between "the strongest human being" and the strongest wisdom, and hoped to spread the seeds of artificial intelligence to more people and cultivate more teams with three generations.

  Jiang Yiyan, a film and television actress, said that the public has a lot of thirst and questions about science and technology, and she asked them with these questions. "Robots appeared for the first time in the sci-fi movie Metropolis, and with the development of science and technology, the technology in many movies has been gradually realized. I also hope that the progress of science and technology will gradually bring changes and influences to life, so that more people can be freed from mechanized labor and feel more subtle emotions."

  Sa Beining, the host of CCTV, said that the witness group could ask questions from its own perspective. For example, the shooting robot arm misses every shot, and Jiang Yiyan asks: How about the robot arm hitting nobody? Asking questions from people in different fields can open more windows and let people see the difference between today and the future.

  In the program, the "strongest human" team, which consists of Jeremy Lin, the superstar of the National Professional Basketball League, Bao Chunlai, the national badminton player, Zhao Zhongxiang, the host of CCTV, and Lin Yu, the chief simulation portrait expert of Shandong Provincial Public Security Department, will challenge artificial intelligence.

  Bao Chunlai was very excited in the confrontation with the drone to play badminton. "In the past, in the training competition, the opponents were all people. This time it was a machine, and it felt very enjoyable. In my impression, artificial intelligence exists in TV and movies, and it can be very close to life. "

  Special idea: the audience floating in the air

  Creativity and content have achieved a "strong alliance", but how to show it?

  When people walk into the recording scene, they will find that the design and construction of dancing beauty such as the suspended audience seats in "Wit Beyond Man" presents a strong sense of science and technology and the future.

  The 11 "spaceships" on the recording site can accommodate 506 spectators. "Just now, in the audience, some people said that they had come to see how the audience got on. We used coercion wire to hang it, and the audience recorded it for two or three hours from the ladder. " General director Chen Qiyi said.

  The audience boarded the "spaceship" and had to fasten their seat belts after sitting firmly. Many people think they have entered the House of Representatives of Star Wars Rico Lausanne.

  The robotic arm held up the four corners of the ground to form a pyramid, and the cool opening made the host Gao Bo shout: "This is the coolest opening since I hosted my career! I seem to be from Mars. "

  "From the beauty design to the reality, the restoration degree of this beauty effect has reached 100%, which is better than we expected." Chen Qiyi, the general director, said: "In the past, we all had to learn from and copy from foreign countries, and there was little originality. Can China people make original programs? I think there is! This program is our answer, and I hope this stage can become the iconic symbol of "Wit". "

  As a popular science program focusing on artificial intelligence, "Wit Beyond Man" aims to become an accelerator in the innovation relay race, popularize scientific knowledge, spread scientific spirit, encourage innovation and entrepreneurship, improve the scientific literacy of the whole people, release the innovative wisdom of the whole people, and stimulate the innovative power of the whole people.

  It is reported that the program will end with an AI Festival, and CCTV and China Academy of Sciences will jointly award the "Wit Pioneer" award. All artificial intelligence projects that win in the program will have the opportunity to win the annual award.

Apple’s incoming AI mobile phone "iPhone moment" is coming?

When mobile phone manufacturers rushed to add more AI, 2024 was called "the first year of mobile AI". However, Apple, which has always been regarded as the pioneer of smart phones, has been slow to act. Recently, Apple announced that it would abandon the car-making project, and it is turning to the field of generative AI in an all-round way, and news related to AI mobile phones is constantly coming out. For Apple, in the face of declining sales and market, price reduction is the competition for the stock market, while AI is the preemption of the incremental market.

Introducing external large model

According to foreign media reports quoted people familiar with the matter on Monday, Apple and Google are actively negotiating, hoping that Google’s generative artificial intelligence model Gemini will support some new functions of iPhone software this year. In addition, the source also revealed that Apple recently discussed with OpenAI and considered using the GPT model.

It is reported that Apple is preparing new functions based on its self-developed artificial intelligence model for the upcoming iOS 18, but these are all concentrated on devices, not through the cloud. Therefore, Apple is also looking for some partners to support generative artificial intelligence functions, including the ability to create images and write articles based on simple tips.

After giving up the car-making project, Apple is currently facing tremendous pressure in the field of artificial intelligence. Compared with competitors Microsoft and Google, Apple has been slow to introduce generative artificial intelligence, and Google and Microsoft are already integrating artificial intelligence into their products. Last month, Apple CEO Tim Cook said that the company planned to disclose more about its plans to put generative artificial intelligence into use later this year, adding that the company was making "significant" investments in this field.

The cooperation negotiations that broke out this time may mean that Apple’s efforts in artificial intelligence are not as far as some people hope. Therefore, people familiar with the matter said that Apple’s move to find partners may be wise. If the negotiations are successful, Apple will gain new functions in generative artificial intelligence, and Gemini will gain a key advantage in having billions of potential users.

At the same time, it also means that the two companies will "kiss each other." According to the agreement reached between Google and Apple, Google pays Apple billions of dollars every year, making its search engine the default option for Safari web browsers on iPhone and other devices. It is worth mentioning that in view of the huge scale of both parties, the potential agreement may lead to further antitrust review of the two companies.

Apple’s process related to AI mobile phones has always attracted much attention. In 2023, many media reported that Apple was developing a big model Ajax. In January 2024, some developers found Siri’s code related to OpenAI and ChatGPT in the developer preview version of Apple’s operating system iOS 17.4. The code shows that Apple is developing a new version of Siri supported by a big model. This has triggered speculation in the industry about iOS 18 that has not yet been launched. Many people think that iOS 18 will deeply integrate generative AI technology and redo iOS built-in applications with AI, especially Siri.

Save sales

For Apple, AI mobile phone is a brand-new and huge market. Since entering the China market in 1993, Apple has always been regarded as the representative of high-end mobile phones. In the era of smart phones, Nokia, the "tears of the times", was eliminated; There are many domestic flip phones whose names can’t be remembered. It seems that only Apple will never fail. However, 30 years later, this situation has undergone a subtle change.

Recently, the report released by Furui Group said that in 2023, the sales volume of Apple mobile phones in China dropped slightly by 3%, and the sales volume in the first week of 2024 plummeted by 30% compared with the same period in 2023. The report also predicts that the sales of Apple’s mobile phones in China may show a double-digit decline in 2024 in the face of multiple attacks from China brands such as Huawei and Xiaomi. Subsequently, Apple reported that China’s revenue dropped by 13%.

In order to cope with the weak demand in the smart phone market, Apple China official website recently launched a rare promotion campaign to reduce the price of its iPhone 15 series products by 500 yuan, including the most expensive iPhone 15 Pro Max.

Major General Ding, an industry observer, told the beijing business today that the price reduction of Apple official website showed that the sales of iPhone 15 series were less than expected before, and there was pressure to clear inventory at the end of the year. Under the multiple pressures of the high-end local brands in China, represented by Huawei, and the launch and sale of Samsung’s flagship new machine Galaxy S24 series, Apple needs to release the old inventory as soon as possible and lay the foundation for the new machine sales in 2024.

In Major General Ding’s view, Apple’s strategic adjustment is relatively slow. In terms of imaging technology, it has been overtaken by the head brand of the Android camp, but it is slow in folding screens and AI models, resulting in the gradual loss of users.

Canalys analyzed that in the past two years, thanks to the steady demand of the high-end smart market, Apple iPhone has shown tenacious vitality. However, the re-emergence of Huawei in Chinese mainland and local competition will pose a challenge to Apple’s sustained growth when the demand for high-end mobile phones in other major markets such as North America and Europe tends to be stable. "In the new year, Apple must seek new market growth points and ecosystem advantages to revitalize the iPhone business." Canalys wrote in the report.

Samsung Galaxy S24 series mobile phones are regarded as a strong proof that AI affects sales. According to official data, the sales volume of Galaxy S24 series has exceeded 1 million units in 28 days after it was launched in South Korea, which has set a new record for the sales volume of Samsung S series mobile phones to exceed one million units, which is three weeks faster than that of the previous Galaxy S23 series.

Coincidentally, although Samsung released its own Gauss model in November 2023, the Galaxy S24 series uses Google’s Gemini, and the China version uses Baidu’s ERNIE Bot. At present, the main AI functions of Galaxy S24 series include two-way real-time translation during call and creative image editing.

How far is AI iPhone?

After the explosion of ChatGPT last year, Huang Renxun, CEO of NVIDIA, put forward that "the iPhone time of AI is coming", indicating that the AI industry has reached a point like the revolutionary subversion brought to the mobile phone industry when the iPhone was born.

Today, AI’s real iPhone may be coming. However, many people think that we still have a long way to go with the veritable AI mobile phone. According to some insiders, no matter whether the big model is self-developed or open, the products that have been labeled with AI mobile phones are nothing more than image processing, search and other functions, which are far from the real intelligent form.

Gartner, a research organization, pointed out that AI mobile phones should be equipped with corresponding hardware and software functions, which can realize seamless integration and efficient execution of AI driving functions and applications on mobile phones; These phones can run basic or fine-tuned AI models locally and generate new derivative versions of content, strategies, designs and methods. In other words, only when AIGC actually runs on the terminal can AI be considered as landing on the mobile phone.

Zhang Xiaorong, dean of the Institute of Deep Science and Technology, believes that in terms of value potential, AI is expected to refresh the business model of the mobile phone industry and even reconstruct the previous pattern. But at the present stage, the strategic awareness of mobile phone manufacturers is far ahead of technology and ecology. Building momentum around the concept may boost sales in the short term, but the vision is not equal to reality after all.

Zhang Xiaorong mentioned that it should also be noted that while AI mobile phones enhance the sense of experience, they will also cause users’ anxiety about data and personal privacy. At present, users who have doubts about App snooping data can also use different Apps to distinguish them, and avoid privacy leakage by not letting an app get too much data. Assuming that the AI ? ? mobile phone can get through all the apps, users naturally cannot avoid it.

At this level, the AI ? ? phone has not yet ushered in its iPhone moment, but obviously, it is worth waiting for.

Changjiang, Hainan: kapok comes in spring

  "It’s different in the south, middle and spring, and the city is full of kapok." At present, it’s a good time to enjoy kapok in Changjiang, Hainan.

  Changjiang River, known as the "hometown of kapok", is one of the areas where kapok is concentrated. 2-mdash per year; In March, the landscapes of Baoshan Village Kapok Terrace, Paian Village Kapok Railway and Changhua River Kapok Red in Changjiang River formed Hainan’s unique beauty of stepping into the spring. When kapok bloomed, it was the first time when rice was planted, which vividly showed the freehand brushwork picture of "spring ploughing in the flowering season" and formed kapok unique to Asia — Paddy field farming system.
Every year, during the flowering season of kapok in Changjiang, painters and tourists from all over the country also come here.

Over-packaging in fruit shops is too rampant, and it is really not advisable to dress fruits layer by layer.

  Some fruits that ordinary people are used to picking are also packed into boxes. Cao zhengshe

  "Not only can’t you choose, you can only buy a few in the box!" Ms. Chen, a citizen who wants to buy two pounds of apples, is very puzzled. Several fruit shops at home have been "upgraded", but it is more troublesome to buy fruits than before: many kinds of fruits are packed in plastic boxes, so you can only buy them by the box.

  The reporter visited and found that this is not a case. Many fruit shops have begun to "dress" the fruits that were sold in the past: sealing them with plastic wrap, putting them in plastic boxes and putting them on plastic bags. At the same time of excessive packaging, it is inconvenient for ordinary people to shop. Why is the trend of fruit packing set off? What’s the logic behind it? For this phenomenon, what means are there to crack it? The reporter conducted an investigation into this.

  phenomenon

  Scattered fruits are packed in boxes.

  In the "Baiguoxiang" fruit shop in Sanyuanli, the salesman picked up a bunch of grapes in his left hand, cut off the withered grapes one by one with scissors in his right hand, and finally put them into a disposable plastic box. Around him, layers of packed kumquat, apples and so on have been packed.

  Many fruits that ordinary people are used to picking are also packaged and put into boxes. Nanguo pear, though marked with a catty of 7.5 yuan, has been wrapped in plastic wrap and repackaged in plastic boxes. Several customers picked it up one by one, studied it and put it down again, but no one bought it for a long time. "It’s all in the box, and you can’t pick it. I don’t know if it’s fresh!" A customer said. In the past, almost all fruits such as pears and apples were in bulk. After customers finished weighing and calculating money, the quantity and quality could be controlled by customers themselves. Now, the choice is much smaller. Take Nanguo pear as an example, one serving of seven or eight pears can’t be eaten at a time, and it’s no good to buy less; Want to buy more, can only buy two, a total of 16.

  A similar situation is more common in many chain fruit shops. The reporter visited Guoduomeibei Taipingqiao Store and Huayuan Road Store one after another and found that most fruits, such as apples, pears, oranges and kiwis, were packaged, some were covered with plastic wrap, some were packed in hard plastic boxes, and there were relatively few bulk fruits. The reporter counted that there are about four or five hundred boxes of all kinds of fruits sold in boxes in each fruit shop.

  Some consumers said that in the past, this kind of fruit packed in boxes was often sold online and other channels. "I went to the fruit shop to buy some fresh fruits, but I found that many fruits in the store were also wrapped and I couldn’t choose at all."

  Explore the cause

  Merchants for the convenience of stop loss chart

  Why is the trend of fruit boxed sales getting worse?

  A salesperson at a fresh supermarket named "Good Fruits and Vegetables" in Chaoyang Beiyuan said that these fruits are scattered when they are purchased, and then they are packed into plastic boxes after being transported to the store. "The packaged fruits are beautiful and clean, and fruits like oranges and pears are also bad in bulk."

  "Those who sell fruit are afraid of bad fruit, which is the most crucial reason!" Zhou Zheng (pseudonym), the owner of a fruit shop, told reporters that the main reason for packing fruits is that merchants want to stop losses: First, when packing fruits, customers will not touch them back and forth like picking bulk fruits; Secondly, boxing is one of the measures to keep fruits fresh, which can extend the sales time.

  The reporter noticed that the sales methods of fruit boxed are mainly concentrated in the newly upgraded fresh fruit supermarkets and high-end supermarkets. In traditional vegetable markets and cheap supermarkets, a large number of fruits are often sold in bulk.

  Zhou Zheng explained: "There are also some boxed fruits. Because the packaging is exquisite and the price can be raised, merchants prefer to box them." The increase of packaging cost will inevitably be included in the price of fruit; However, some boxed fruits have extended the sales time, and the freshness will inevitably be "discounted".

  Reduce the amount at the source

  The convenience of merchants also brings greater negative impact on the environment: in the past, ordinary people bought fruit and at most bought a plastic bag; Nowadays, the fruit is first covered with plastic wrap, then put into a plastic box, and finally put into a plastic bag, resulting in a "three-piece set" of packaging waste.

  "About eight or nine thousand disposable plastic boxes can be used in a month." The person in charge of a fruit shop with an area of more than 100 square meters admits that the cost of these disposable plastic boxes ranges from a few cents to a few cents, and they are basically online shopping.

  The reporter searched for "fruit disposable plastic boxes" on Taobao. There are countless kinds of goods. In the top three stores, a strawberry packaging box is selling well, each box contains 600 boxes, and the price is 215 yuan. The monthly sales volume of this product reached 1,387 boxes, and this packaging box sold 830,000 boxes in one month. "The materials of these plastic boxes are similar to mineral water bottles, and they are all non-degradable." The person in charge of this store bluntly said that a large part of these plastic boxes were sold to many well-known fruit fresh supermarkets.

  "White pollution" has become a world problem. "Like disposable lunch boxes, fruit plastic packaging is mostly thrown away by ordinary people." Sheng Min, secretary-general of China Renewable Resources Recycling Association Recycling Plastics Branch, said that besides reducing the amount at the source, there should be reliable and effective recycling channels. If there is a sound garbage sorting system, plastic packaging will be used more effectively through recycling channels. For example, Europe mainly subsidizes the recycling of renewable resources through compulsory policies adopted by the government; Japan, on the other hand, does a good job of sorting garbage from the source by cultivating national quality.

How should parents give reasonable guidance to children who use new media to become younger?

Chen Qingwen, an associate professor at Tongji University, pointed out that parents should balance the opportunities and risks of the Internet when guiding their children to surf the Internet. Photo courtesy of respondents

  I believe many people have had this experience: in some public places, "Xiong Haizi" played games or watched videos with electronic devices such as mobile phones and tablets, and the volume was so loud that parents turned a blind eye. Relevant research reports show that in China, children’s use of new media tends to be younger and more entertaining.

  On the one hand, new media devices that can be networked, such as mobile phones and tablets, have grown up with a new generation of children and once became a "part" of their bodies; On the other hand, the powerful educational function and interpersonal communication use of new media also make it a sharp weapon for learning and communication.

  As the mother of a post-00 generation child, Chen Qingwen, an associate professor at Tongji University’s College of Art and Media, faces the same problem: How and how often do children use new media? How should parents guide their children to use new media reasonably?

  With these questions, Chen Qingwen and his team randomly interviewed 30 families of children aged 3-10 in Shanghai to learn about children’s use of new media, parents’ attitude and involvement in children’s use of new media, and children’s views on parental involvement. On this basis, suggestions are given, and the research results are published in the core journal "Journalist" in August 2019.

  From "TV Children" to "New Media Children"

  As a post-1970s generation, Chen Qingwen admitted that he "grew up watching TV". When he was a graduate student at Fudan University 15 years ago, he studied the newly-emerging children’s channel in China. She said that the transition from "TV children" to "new media children" was even faster than the growth of a generation. And this change has brought a kind of trouble to parents: it is difficult to guide children to use new media reasonably with reference to their own experience.

  Some people may ask, how can they bring up the next generation when there was no TV in the older generation?

  "Because the new media is more interactive, participatory and creative than the traditional media, but without learning and guidance, children may just regard the new media as TV or game consoles." Chen Qingwen explained that, at the same time, new media are everywhere, and the content is all-encompassing, which is very different from traditional TV and other media. You can leave TV at home, but you can’t live without the Internet and mobile phones. In modern cities, "portable" and "always online" have become the common points for people to use new media.

  Chen Qingwen felt that "new media children" were born from the moment parents provided their children with new media equipment.

  Among the 30 families interviewed, one-third of the children have their own new media equipment, and the other two-thirds share it with their parents, many of whom will leave their unused new media equipment for their children to use. In terms of use, most children play games, followed by watching videos, and the third is the homework assigned by the school.

  According to statistics, more than half of the children use it for a long time, especially on weekends, almost for more than two hours a day. In the trend, many children in the kindergarten group have used new media for a long time, and the use time tends to lengthen with age. In addition, compared with the primary school group, the kindergarten group has a higher proportion of its own new media equipment, which shows that the use of new media is younger.

  In March this year, the Research Report on the Internet Use of Minors in China in 2018 jointly issued by the Youth Rights Protection Department of the Central Committee of the Communist Youth League and China Internet Information Center showed that as of July 31, 2018, the number of underage netizens in China reached 169 million, and the Internet penetration rate of minors reached 93.7%, which was significantly higher than that of the national population (57.7%) in the same period. According to the report, this is a direct manifestation of the expansion of Internet coverage and the decline of mobile traffic charges in China in recent years, and it is also closely related to minors’ strong interest in the Internet, strong learning ability and great application demand.

  Don’t let machines take the place of parents’ company

  In the interview, the research team found that children’s use of new media is mostly due to lack of companionship, especially preschool children. Because parents are busy and have no friends to play with, children have to turn to mobile phones and tablets; With the increase of age, more and more children choose new media.

  Some parents even choose to use new media instead of themselves to accompany their children. In public places such as restaurants, children are often seen watching videos while eating, perhaps just to let their parents "have a good meal". "She is good with this and doesn’t make any noise, as long as she doesn’t make any noise." A mother said.

  The interview also found that with the increase of age, more and more children are more willing to choose new media than playing with friends; And the older children are, the less satisfied they seem to be with their new media use time. Most of the respondents in the primary school group felt that their use time was insufficient, and one girl felt that two hours a day was not enough.

  "When parents use new media instead of accompanying their children, the actual price paid is likely to be huge." Chen Qingwen pointed out in the research report, "As they get older, they are more likely to rely on new media. At this time, even if their parents want to accompany them, they may continue to immerse themselves in communication with machines. When machines replace humans to accompany children, even if people come back, the relationship between children and machines is unbreakable. "

  Chen Qingwen combined expert opinions and personal experience to give some suggestions to parents. "If you want to control underage children’s use of new media, try not to let them own their own equipment, just lend it to him, that is to say, give children the right to use it, while parents retain the right to control it. As for the balance between control and privacy, you need wisdom."

  She also said that although the current academic research is inconclusive about when to start controlling children’s use of new media, she feels that parents who are determined to control their children should take action as soon as possible. "It would be much better to let him know that parents should take care of it early than suddenly."

  Why can other children play computer games, but I can’t?

  In this "equipment battle", "children crying and parents yelling" is a common scene. The research team found that most children’s tricks are crying and "lai", and they can play as long as they can until their parents take away the equipment.

  Interestingly, on the question of whether parents are worried about their children’s use of new media, parents’ attitudes are polarized: 17 are worried, and 13 are not worried, either very supportive or very opposed.

  In the interview, some parents thought that "this is a trend" and "this thing will be accepted sooner or later", so they were not worried at all. A mother said: "everyone has it, but they just can’t fall behind." If she doesn’t understand, she feels like she is behind others and can’t keep up. "

  The attitude of parents who hold opposite opinions is also very clear, and their concerns are mainly reflected in three points: First, they are afraid of their children’s addiction; The second is to worry about the harm to vision; The third is to worry about the negative impact of inappropriate content such as violence.

  Chen Qingwen believes that such "two extremes" attitude makes parents’ work of disciplining their children in trouble. "Why he can I can’t, this is a child’s question. For example, children will say that classmates can use computers when they go home. Why can’t I? "

  Another reason is the change of family education style in China. “‘ Authoritative education ’ It is not easy to work. In the past, parents could answer no, but now they are likely to get a crying and keep asking. After all, children’s energy is much better than ours. "

  The research team also found that, as in the TV era, the way parents intervene in their children’s use of new media is mainly "restriction", and the time limit is more than the content limit.

  Most parents in the interview only know that their children are playing games or watching videos, but they don’t know what games or videos their children are playing. Some academic studies believe that restrictive guidance strategies can not only effectively help solve the problems that children may encounter on the Internet, but also easily lead to the decline of the quality of parent-child relationship or frequent conflicts.

  For children who are out of control, whether they cry, lose their temper or cheat, the parents interviewed said: "Let her cry", "Ignore her" or "yell at him", and some parents will be patient and reasonable, but children will still enter the cycle of yelling if they don’t listen.

  The mother of a 9-year-old boy said that she usually talks reason first and scolds him if she doesn’t listen. If she scolds him, she will have to yell at him at him at a higher volume. If she doesn’t, she will have to be punished, such as not using new media for a few days or increasing the number of homework. Most parents can insist on not using their children’s noise, but the children’s crying or losing their temper will continue.

  Academic research proves that parents’ positive intervention is more effective.

  "We just did a small-scale interview in Shanghai." Chen Qingwen said, "If you want to give scientific advice, you need to do extensive and long-term investigation and research in different cities and rural areas across the country."

  But before that, some countries encountered these problems earlier than China, and their academic research may provide reference.

  Chen Qingwen introduced that since the 1980s, the research on parents’ involvement in children’s media use has been popular in the United States. After 1990, the American government emphasized the role of parents in family policy, and related research received more attention. The research points out that the two main intervention methods adopted by parents are "making rules" and "restricting"; The actual behavior of parents can be divided into positive intervention methods such as parent-child discussion and negative intervention methods such as prohibiting or restricting use, and parents adopt the mode of sharing viewing between parents and children.

  In another paper on the use of new media by minors by British scholars in 2007, the author divided the intervention strategies of parents for their children to use new media into four categories. In addition to joint use and restricted use, parents will also adopt "technology restrictions", that is, use technology software or set restrictions on their children to prevent them from using unauthorized digital media content; And monitor children’s use of websites, letters and games in different ways. Their conclusion is that when parents take active measures to intervene their children’s use of new media, such as sharing or discussion, the negative influence of their children’s use of new media can be effectively reduced.

  Domestic research on the media also believes that parents’ intervention can bring positive results.

  For example, in the psychological aspect, the correct intervention of parents and families can reduce teenagers’ psychological anxiety, help build self-confidence and self-esteem and affect teenagers’ mental health; In terms of learning and risk reduction, parents’ active intervention in media use can improve teenagers’ learning effect, reduce the possible negative impact of violent content in the media, affect the formation of children’s gender role attitude, reduce children’s fear response to media content, and reduce some network risks that children may encounter.

  At the same time, parents’ ideas and the motivation and methods of intervention are extremely important.

  Foreign studies have found that the more parents want the Internet to have a positive effect on their children and think that the Internet will have a negative impact on their children, the more they will get involved in their children’s use of new media. Domestic research also points out that the more time online is strictly restricted by parents, the more recreational motivation teenagers tend to use the Internet.

  "The key point may not be whether children should use new media or how to use new media at all, but where the parents are and where the children’s minds are. Studies in different fields have pointed out that modern society is busier than before, and how parents create a happy parent-child environment will become an increasingly important issue. Quality companionship between parents and children is one of the necessary conditions for shaping parents. " Chen Qingwen’s interview report wrote.

  Communicate with your child with your heart

  What do children think of their parents’ control? The interview results show that on the whole, half of the children think that their parents are reasonable; At the same time, with the growth of children’s age, the proportion of recognition of parents’ intervention control has increased. And "making rules together" and "keeping your word" have become the common standards for children to measure the rationality of parental discipline.

  Taking nine children in the kindergarten group in the interview report as an example, Min Min, a 4-year-old (all minors below are pseudonyms), feels that his parents are much more in charge; Tingting, 5, feels that her parents don’t care much because they are reasonable. Zhu Zhu, a 5-year-old, said that she was afraid of her father because he was very fierce when he was angry and would say, "I’m telling you! I’m telling you! No matter how, I will kick you downstairs "; Kiki, Doll and Lingling, both 6 years old, are afraid of their mother and think her mother is too fierce.

  Among the 21 children in the primary school group, 13 children feel that parental control is reasonable, 5 children feel unreasonable, and 3 children are uncertain. Xiao Han, a third-grade student, told the interviewer that she felt that the parental control was sometimes reasonable and sometimes unreasonable. The unreasonable reason was that the mobile phone was forcibly taken away before the agreed time. "My mother said several times that she would play for me for 10 minutes. I didn’t expect that when it was almost two minutes, she said that it was 10 minutes. I didn’t want to, so my mother dragged me away. She said that it was evening and I couldn’t play any more."

  The interview report suggests that from the perspective of social environment, there are two urgent things: first, timely education courses related to new media literacy should be provided at different stages of children’s growth; The second is to improve parents’ ability to master new media and new technologies.

  "Not all parents have time and energy to participate or study independently. I think we can start with school education and issue some principles and suggestions for children to take back to their parents." Chen Qingwen explained.

  In addition to improving their understanding of new media and technologies, parents should also attach importance to communication between parents and children and accompany their children to use new media by guiding participation. Especially in the method of making rules, parents need to talk to their children often. "In fact, kindergarten children have a very clear concept, this is good, how long should it take. If the rules are made by the children themselves, or if the parents discuss with him, the children will be more willing to abide by them. "

  When attending international academic conferences, Chen Qingwen often discusses these issues with foreign scholars: when to give children new media equipment, how long the screen time should be in a day, and when to let children have their own social media accounts. "Although some organizations will give suggestions, for example, the screen time is no more than one hour or two hours a day, and general social software suggests that people are over 14 years old, but parents have different ideas, different social situations, different family situations, and different children, so you can refer to some research-based suggestions, but in the end you have to find a way that suits you. I don’t think there is an absolute standard."

  "According to the needs" is Chen Qingwen’s main basis. Her son rarely contacted new media when he was in kindergarten, but when he saw that other children had their own mobile phones, he said that he also wanted to have their own mobile phones. But this wish has not been realized until now that his son is going to middle school, because his son has no need to carry a mobile phone. When she entered middle school, her son needed a computer for some of his homework. The school asked for a laptop for her child, so she bought the laptop she wanted, but only if it was used for study and could not be loaded with games. "At present, the school has just started, and there are still any problems in the future. I am also walking and watching."

  "In our research, we found that intentional is better than unintentional. As long as you are intentional, children can feel it. My suggestions are: teach students in accordance with their aptitude, learn from each other, and communicate with your heart. From the perspective of communication, intentional communication can enhance feelings and reduce misunderstandings, which is actually the most effective method. " Chen Qingwen said.

  Ministry of Education: The highest standards and strictest measures go all out to do a good job in the 2020 college entrance examination.

  Official website, the Ministry of Education, issued a notice on July 2nd, stating that the education department and the member units of the Inter-Ministerial Joint Conference on the Unified National Education Examination should strictly do a good job in epidemic prevention, examination safety, examinee service, enrollment and other work of the college entrance examination with the highest standards and strictest measures, so as to ensure the realization of "safe college entrance examination", "sunshine college entrance examination" and "fair college entrance examination".

  First, the green channel for resident ID cards. Candidates who need to be expedited and have their ID cards renewed will be given priority in acceptance, certification and delivery.

How did the zodiac come from? Why is the rat the first?

Source: Economic Daily
Time is slowly moving forward, and the Spring Festival is coming. According to the year of the zodiac, 2020 should be the year of the rat in the lunar calendar. Similarly, according to the year of birth, we all have a "genus". So, how did the zodiac come from? Why does the seemingly unremarkable mouse rank first?
The "Evolution History" of the Zodiac: It has been recorded in the pre-Qin period.
The zodiac, also known as the "animal sign", includes rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs. They have a long history, and as early as the pre-Qin period, relevant records appeared in ancient books.
Data Map: The picture shows the element light group in the Year of the Rat. Yu Jing photo
In December 1975, two batches of bamboo slips of Qin Dynasty were excavated in Yunmeng Sleeping Tiger Land, Hubei Province. Among them, the contents of "thief" in "Japanese Book" are close to those in the zodiac, such as "son, mouse, thief with sharp mouth and rare beard; Ugly, cattle, thieves have a big nose and a long neck … "
By the Han Dynasty, the zodiac was basically shaped. In the Eastern Han Dynasty, Wang Chong wrote Lun Heng, in which he mentioned: "Yin, Mu Ye, its birds and tigers are also … Hai, Shui Ye, its birds and dragons are also ……", which stated the twelve zodiac signs and the corresponding twelve earthly branches.
With the passage of time, the sayings about the Chinese zodiac have been improved, gradually accepted by people and passed down to this day.
For example, in the Southern Dynasties, Shen Jiong wrote a poem "Twelve Genus", in which he wrote: "The case of mice and dust, cattle and sheep came down at dusk. The tiger roars in an empty valley, and the rabbit opens to the window. Dragon Ji is far green, while snake willow lingers near. Malan Fang is far away, and sheep are planted in spring. The monkey chestnut shames the fragrant fruit, and the chicken’s feet lead to a clear cup. The dog is pregnant with things, and the pig is stupid. "
How did the zodiac come from?
People can always talk about the anecdotes of the zodiac, but their origin is still inconclusive.

There is a saying that the zodiac culture originated from totem culture and has different symbolic meanings: since ancient times, different tribes have their own animals to worship, such as cattle, which is a symbol of farming society. According to legend, Emperor Yan of Shennong is a "cow’s head", so the descendants of Emperor Yan take cows as totems.
Others said that the zodiac originated from animal worship. In primitive society, human productivity is very poor. Livestock such as pigs, cows and sheep are closely related to farming activities. Animals such as tigers and snakes may threaten people’s own safety, and people will feel fear … All these reasons eventually lead to the formation of the zodiac.
In addition, some scholars put forward a view: the zodiac is not only related to real animals, but also has an "astronomical" background, which is related to the ancient people’s association with the stars. Wu Ma, Chen Long and Yin Hu are related to the images of these constellations.
Of course, there is also the saying that "the zodiac is foreign", but it has not been widely recognized.
Why do rats rank first in the zodiac?
As a symbol system of chronology, the mouse, which seems inconspicuous and a little annoying, ranks first among them. Why?
Data Map: The colored lights in the shape of cartoon mice are very eye-catching. Photo by Luo Bo
Ancient scholars in China once explained it from the perspective of twelve o’clock a day and night. When heaven and earth are in chaos, rats just come out in the middle of the night and bite out a gap between heaven and earth, that is, "rats bite the sky", so they belong to rats; After the beginning of the world, people had to farm for a living, and cows were the main force of farming at that time, so ugliness corresponded to cows and so on.
People in China believe that mice have strong reproductive ability, and the ancients expected the reproduction of life and the prosperity of extended families, so they came up with the fertility concept of many children and many blessings. In Ren Yu’s Atlas of the Twelve Zodiacs at the end of the Qing Dynasty, five rats were grabbing melon seeds in a jar, and "seed" has the same sound as "zi" and also stands for "many children".
There was another interesting question before: Why are there no cats in the zodiac? In fact, the answer is very simple. Cats originated in Egypt, and the Chinese zodiac was introduced to China after it was finalized, so there is no way to include them.
Zodiac rats in legends and stories
However, mice are not always stealthy in ancient legends, stories or books.

There is also a novel in the late Qing Dynasty called "The Biography of the Eight Immortals", which also mentions a legend related to rats: in a big flood, the bridge was washed away, and rats bridged the bridge to save people, and finally they exhausted their strength and were swallowed up by the flood. The immortal was moved, gave the mouse a fairy fruit, and accepted it as a disciple, and finally helped the mouse become immortal.
In addition, there was a book in the Qing Dynasty called "Dream Garden", which recorded that there was a toy in eastern Guangdong called "suncus murinus", which sounded like counting money. Rats can make a sound like counting money. In the old days, some places used this sound as a sign of good luck. In auspicious New Year pictures, paper-cuts and lanterns, there are also mouse images.
In fact, to a certain extent, the zodiac is a vivid representative of the twelve earthly branches, each with rich legends, and then gradually merged with some folk beliefs. In modern society, they are also regarded as the mascots of the Spring Festival.

Do not set off physical fireworks! Here is the correct way to open the "fireworks" at the opening ceremony of Hangzhou Asian Games.

The highly anticipated opening ceremony of the 19th Asian Games in Hangzhou will be held at the Hangzhou Olympic Sports Center Stadium ("Big Lotus") on the evening of September 23rd. With regard to the highlights of the opening ceremony, the reception desk has "spoiled" a thing or two through an interview with Sha Xiaolan, the general director and producer of the opening ceremony, and the 16-second trailer released on September 16th. So what kind of surprise will the opening ceremony of Hangzhou Asian Games present? The answer will be revealed on September 23rd. One thing is certain, and the difference between the opening ceremony of this Asian Games and previous large-scale events is that no fireworks are set off throughout.

In the impression of many viewers, for the opening ceremony of large-scale sports events, the grand fireworks show is always the finale of the repertoire. Without fireworks, how will the lively "atmosphere" of the opening ceremony of Hangzhou Asian Games be reflected? In this regard, Sha Xiaolan said frankly in an exclusive interview with the media on September 17, "We have made great determination to cancel the fireworks display."

"As we all know, as long as fireworks are set off, there will be smoke and dust in the air and there will be pollution. No fireworks is to express our environmental protection concept to the whole world. " Sha Xiaolan said that canceling the physical fireworks display is adhering to the green, intelligent, thrifty and civilized concept of hosting the Asian Games, and passing on the concept of environmental protection at the most concerned moment like the opening ceremony.

Sha Xiaolan emphasized that not setting off physical fireworks does not mean that the opening ceremony of the Hangzhou Asian Games will be less exciting, and the team will innovate and present better audio-visual effects with the power of science and technology. "We use digital technology, 3D animation, AR technology, etc. to show fireworks in front of TV viewers and live audiences."

Fireworks made by virtual technology are even brighter and more beautiful than the real fireworks. "Let me give you an example. Watching fireworks at ordinary times must be looking up, but watching fireworks on TV can see fireworks overlooking the angle of view, that is, fireworks blooming in the bustling scenes on both sides of Qianjiang River. Looking down, what kind of effect will the fireworks look from top to bottom? "

At the same time, Sha Xiaolan also gave a viewing guide: everyone watched the opening ceremony electronic fireworks display through TV, mobile phones and other ports, and the overall viewing effect was better than the scene. The creative team will display the grand occasion of the electronic fireworks display on the banks of Qianjiang River, the Hangzhou Olympic Sports Center and the "Big Lotus" in a 360-degree panoramic view from the angles of leaning, leaning and side view through digital technology, which will be a highlight moment of the opening ceremony.

Previously, the opening ceremony of the Hangzhou Asian Games had successfully completed the fourth rehearsal. Next, the creative team will re-adjust the video, costumes, props and some equipment, and will choose the opportunity to rehearse again before the official performance.
