For friends who like swimming, here are a few suggestions:

1. Before swimming, you should do warm-up activities, do gymnastics, run, exercise your body, stretch your muscles and joints, and then swim.

2. Before swimming, you should know the overall water condition of the swimming pool, especially when you go out to swim in the reservoir, you should pay more attention to the speed and depth of the water, and don’t swim in unfamiliar waters to avoid drowning accidents.

3. Don’t swim on an empty stomach. The physical consumption of swimming is higher than that of general exercise. Swimming on an empty stomach can easily lead to a rapid drop in blood sugar in the body, resulting in dizziness, dizziness, limb fatigue, palpitation and other discomfort. (synthesis)

The finals of the students’ baseball league on both sides of the Taiwan Strait have been held for four times, and the campus exchange activities have become an important bridge to narrow the distance between students on both sides of the Taiwan Strait and establish friendship. On November 14th, students from 12 schools in Taiwan Province visited 11 schools in Shenzhen. Students on both sides of the strait learn from each other, enhance their understanding, and gain growth, friendship and touch through the exchange platform of affection and youth.

The result of the lotus mist symbolizes the everlasting friendship.

Young people in Taiwan Province love to listen to Charlie’s songs.

Joined the New Taipei Chongyi baseball team in U18 group and once again entered Nanshan Affiliated School of Beijing Normal University. In 2018, team coach Chen Zhipeng planted a lotus mist in the school. Five years later, the seedlings of that year are now flourishing and full of vitality.

During the campus visit, Chen Zhipeng recognized the lotus mist he planted at a glance. "I have actually missed it for so many years. Seeing that it grows so well, my feelings are still quite deep." Chen Zhipeng took out his mobile phone and excitedly passed on photos of his planting trees. He introduced that when he visited in 2018, the president of Nanshan Affiliated School of Beijing Normal University suggested that the two schools form a sister school, so a tree of friendship was planted on campus. He said that coming to Shenzhen and this school again this time feels very intimate. "I heard that this lotus mist bears fruit every year. These fruits are symbols of deep feelings. I wish the two sides of the strait unity and long-lasting friendship. I also hope that everyone can come to Taiwan Province to visit and play more."

Music is an inseparable theme in this exchange activity. In the welcome performance in the morning, Nanshan Affiliated School of Beijing Normal University played a piece of Ruan music "Big Fish Begonia" with China national musical instrument Ruan, which left a deep impression on the players of Xinbei Chongyi baseball team. Team member Lin Yuxiang said: "The performance of traditional musical instruments has a shocking feeling in an instant, and it also makes people feel intimate."

After watching the performance, Lin Yuxiang and Ma Lin Jiawei had some "one’s fingers itch". When they saw the piano on a whim, they improvised a four-handed piano. Speaking of "Big Fish Begonia", Marin Jiawei said that he is familiar with this song and loves to listen to the songs sung by singer Charlie. He said: "I met Charlie through mainland TV programs. At that time, he sang a song" Dala Beng Bar ".I thought he was particularly powerful, so I went to the Internet for a special search. Charlie’s songs are very popular in Taiwan Province, and quite a few young people like to listen to them."

Shenzhen children’s original picture book

Taiwan Province of ChinaTeachers and students fondle admiringly.

Taichung Daren Primary School baseball team came to Nanshan Education Experimental Group Lilin Primary School. As soon as they entered the school gate, Daren Primary School students were attracted by the original fairy tale picture books such as "Discover Your Light" and "Halloween Piggy" in the lobby, and they all picked up reading. Wang Guangchun, vice president of Lilin Primary School, introduced that the picture book works came from the fifth student original picture book competition of the school. Students independently wrote stories, created scripts, completed picture books and finally bound them into books.

Lin Nongwei, the coach of Daren Primary School, couldn’t put it down for these original picture books and asked the team members, "Will winter vacation homework be a picture book this year?" The little team member is reluctant to put down the book in his hand, and at the same time he can’t laugh and cry. "Is this really the case?"

Physical education class, a "dodgeball" project, made the baseball teenagers in Daren Primary School put down their shyness and had a "chemical reaction" with the students in Lilin Primary School. Zhong Dingxu, the first baseman of Daren Primary School baseball team, was deeply impressed by the greening of Lilin Primary School. "There are many trees here, and playing dodgeball is just like being in the forest."

The students competed on the playground, and Lin Nongwei learned about the differences in the primary school settings between the two schools from the teachers of Lilin Primary School. "Shenzhen campus after-school delay service is not only free, but also has many types, and it also takes good care of the family circumstances of different student groups. Facing different grades, Yulin Primary School has launched different aerobics, which has been carefully considered. The teaching content is worthy of our study and reference. "

Director of two physical education class exhibitions.

Training in the same field and feeling the spirit of hard work

In order to welcome the guests from Hsinchu Kansai Primary School, Nanshan Experimental Education (Group) Shenwan Primary School invited them to attend two special physical education class classes together.

The content of physical education class in the morning is nunchakus. After standing in line, the children of the two schools, under the guidance of their teachers, began to learn how to clamp sticks and change hands under their shoulders, and also had a left-right stick-changing competition. After the course, nunchakus were given as gifts to the guests who came from afar. The children of Kansai Primary School in Hsinchu took off their hats and bowed to the teacher in a circle and shouted "Thank you". Luo Yongteng, a student of the school, said: "With this gift, I can continue to practice at home in the future. Tonight I will call my parents to share my harvest and tell them that the school in Shenzhen is very big and the course content is very rich. I like it very much. "

The afternoon baseball exchange class is the "home" of Kansai Primary School in Hsinchu. Zhu Yanhua, coach of Kansai Primary School in Hsinchu, believes that although there is a gap in the level between the students of the two schools, the love of baseball by Shenwan students is obvious to the naked eye. Throughout the training course, the coaches of both schools kept a close eye on the movements, and after discovering the technical problems of the students in Shenwan, they also gave targeted technical guidance.

Fan Kai, the right fielder of Kansai Primary School in Hsinchu, was excited when he was training with children of the same age. He said that the "great friends" he met in Shenzhen had a particularly good overall mental outlook. "I admire the spirit of every team member who fought for every ball to the end."

Pairing brings friendship closer.

The baseball team of Xiyuan Middle School in Taichung City began to exchange activities with the applause of teachers and students in Nantou Middle School. In order to receive the baseball team of Xiyuan Middle School, Nantou Middle School specially arranged one-on-one guides for each athlete. Shi Shaoyang, a member of Xiyuan Middle School, was very interested in Shenzhen school uniforms and had a discussion with his classmates in Nantou Middle School. "Shenzhen school uniforms are very clean and youthful. When I was competing in other venues, I saw the school uniforms of Shenzhen students. I always wanted to know, and today I finally fulfilled my little wish. "

The quiet library became lively with the arrival of Xiyuan Middle School baseball team. Zhu Yanlin from Nantou Middle School took Lin Baian from Xiyuan Middle School, a good friend he had just met, for a stroll. Although they had known each other for a short time, after some conversation, they had become inseparable. Lin Baian said that the students in Nantou Middle School are very enthusiastic and the library is very big and clean. I came to Shenzhen this time, not only to play games, but also to have a lot of campus activities. I want to have a deeper understanding of campus life in Shenzhen, and I hope to make as many friends as possible.

Walk into the canteen of Nantou Middle School. Li Yuxing, a member of Xiyuan Middle School, was immediately attracted by the chicken leg as big as his face. He kept gesturing with his hands and inquired about the story of the chicken leg to his classmates in Nantou Middle School. Chen Yuying, a student of Nantou Middle School, told him that chicken leg rice is one of the characteristics of Nantou Middle School. Among the gifts for friends in Taiwan Province, there are also small stickers of chicken leg rice. "Nantou Middle School learns to use the most distinctive dishes to entertain great partners from afar."

The year 2023 is the first year for the world to return to the clean air, and it is also the year before the Olympic Games. Looking at the world pattern of badminton in this year, you can almost see the podium of the Paris Olympic Games.

On December 13th, the year-end finals of badminton will be held in Hangzhou, China. The team members are:

Men’s singles: Shi Yuqi, Li Shifeng, Ansailong, antonsen, Jonatan, Jin Ting, Nara Okada, Kun Lavoute;

Women’s singles: Chen Yufei, Han Yue, An Xiying, Jin Jiaen, Dai Ziying, Marin, Zhang Beiwen, Mariska;

Men’s doubles: translated by Liang Weikeng/Wang Chang, Liu Yuchen/Ou Weiyi, Alfian/Adianto, Furic/Moulana, Jiang Minhe/Xu Chengzai, Baomu Zhuolang/Kobayashi Youwu, A stroop/Anders, Xie Dingfeng/Su Wei;

Women’s doubles: Chen Qingchen/Jia Yifan, Liu Shengshu/Tan Ning, Bai Hena/Li Shaoxi, Jin Zhaoying/Kong Xirong, Matsuyama Naiwei/Zhitian Qianyang, Matsumoto Mayou/Nagara and Kona, Lahayu/Ramadanti, Zongkongpan/Ravenda;

Mixed doubles: Feng Yanzhe/Huang Dongping, Zheng Siwei/Huang Yaqiong, Xu Chengzai/Cai Wei, Jin Yuanhao/Zheng Nayin, Watanabe Yongda/Dongye Yousha, De Chabo/Sha Xili, Deng Junwen/Tse Ying Suet, Chen Tangjie/Du Yihao.

Remind everyone that the qualification for the finals is not based on the world ranking, but on the ranking of the tour, and each association cannot have more than 2 seats. Therefore, Han Yue was qualified for the competition, and He Bingjiao was not allowed to participate.

The distribution of the list of associations is as follows:

Men’s singles: China 2 seats, Danish 2 seats, Indonesian 2 seats, Thailand and Japan 1 seat each;

Women’s singles: 2 seats in China, 2 seats in South Korea, 1 seat in China, 1 seat in Indonesia, 1 seat in Spain and 1 seat in the United States;

Men’s doubles: China 2 seats, Indonesian 2 seats, Korean, Japanese, Malaysian and Danish 1 seat each;

Women’s doubles: 2 seats in China, 2 seats in Japan, 2 seats in South Korea, 1 seat each in Indonesia and Thailand;

Mixed doubles: 2 seats in China, 2 seats in Korea, 1 seat each in Japan, Hongkong, China, Malaysia and Thailand.

The distribution of seats is 35 seats in Asia, 4 seats in Europe and 1 seat in North America. Among them, China is the only association with 10 seats, including 7 from South Korea, 6 from Indonesia, 5 from Japan, 3 from Denmark and Thailand, 2 from Malaysia, 1 from China, Hongkong, China, the United States and Spain.

It can be seen that in terms of the development of badminton in the world, Asia still occupies a dominant position, among which China is still the number one.

It is worth mentioning that the South Korean team rose rapidly this year. They only got three finals seats last year, and this year they jumped to seven, which is rare in badminton history. Their women’s singles, men’s doubles and mixed doubles won this year’s World Championships. Except for men’s singles, all the other four events have the strength to win the championship.

In terms of sub-items, Arcelor in men’s singles is still the only strength, but he is not invincible. An Xiying in women’s singles has already entered an invincible state, but she was injured in the final of the Asian Games. It remains to be seen whether she can recover to the original height after the injury. China is the first team in the world in the three doubles events, but they are not absolutely sure of winning the championship. Chen Qingchen/Jia Yifan in women’s doubles is relatively the most reliable. Zheng Siwei/Huang Yaqiong in mixed doubles was unbeatable last year, but this year she has lost many goals, not only to South Korea’s Xu Chengzai/Cai Wei, but also to her teammates Feng Yanzhe/Huang Dongping. And Liang Weikeng/Wang Chang of men’s doubles still has psychological weakness.

For the China team, 2023 is a year of bottoming out. We were already very sleepy in the first half of the year, but we bottomed out in the second half.

Li Shifeng, Shi Yuqi and Weng Hongyang in the men’s singles occasionally performed brilliantly, and the records of Chen Yufei and Han Yue also picked up at the end of the year. Newcomers or new combinations emerged in the three doubles, such as Liang Weikeng/Wang Chang, Liu Shengshu/Tan Ning, Jiang Zhenbang/Wei Yaxin and He Jiting/Ren Xiangyu, which gave the fans a little idea about next year’s Olympic Games.

As for the gold medals in the Paris Olympic Games, personal prediction shows that there is a high probability of tying two in the Tokyo Olympic Games, but it is very difficult for all five events to enter the finals like the Tokyo Olympic Games.

On December 7th, Beijing time, the Chengdu Table Tennis Mixed Team World Cup is about to usher in the second day of the quarter-finals. At present, China, Japan and South Korea are leading the standings, while Sweden and Germany are tied for second place (in terms of winning and losing), while French, Slovak and China Taipei teams are at the bottom. However, the second stage of the competition has just begun, and the new competition system is more conducive to the backward teams’ turnaround than usual.

According to the arrangement, there will be eight matches in the quarter-finals on the second day, and China, Japan and South Korea will take part in two matches. The match between Guoping and the French team is very worthy of attention. lebrun and Yuan Jianan are tough, so be careful! See below for more details.

The whole World Cup adopts the points system. In other words, although the top eight participated in the second stage, there were no quarter-finals, semi-finals and finals. All teams had to compete with opponents who had not fought with them before, and finally the outcome was determined by the total points, which also made the game more suspenseful. It was difficult to see who won or lost until the final stage.

At present, the three teams of China, Japan and South Korea have all won, but Guoping and South Korea have lost in a single game. However, because they are the total points, it does not hinder the overall situation. Next, everyone will participate in the contest of the second day of the quarter-finals.

As mentioned before, there will be eight team games on December 7th, among which the German-French war at 10:00 am is very interesting. If everyone plays in the main lineup, Germany is obviously better than France, but this time, the six main players of Germany, Ochalov, Qiu Dang, Francesca, Bohr, Han Ying and Mittham, are not here, so it is very difficult to deal with France where lebrun brothers and Yuan Jianan are located.

At the same time, another duel was relatively unnoticed, that is, South Korea VS Slovakia-in terms of strength, South Korea is far stronger than the other side, so there is little suspense in this battle, and even if someone in South Korea is upset, it is difficult to collapse across the board.

The next two games at 12:00 will be the highlight, because the two most powerful teams are about to appear, that is, Guoping and Japanese team, which will face China, Taipei and Sweden respectively.

Relatively speaking, there was not much suspense in the first game, because Lin Yunru, Chuan Chih Yuan and Zheng Yijing, the three core players of the China Taipei team, didn’t come, and it was very unlikely that the rest would break through the national table tennis. Swedish female players are basically no threat to Japan, but the world champion Carlson and the national champion Carlberg among the male players are good in strength, and Zhang Benzhihe and Yukuke Inoguchi may not be able to resist.

At 17:00 pm, the battle between South Korea and Sweden was also interesting, but like Japan, South Korea was mainly wary of Swedish male athletes, and there was little pressure on the women’s line. As for Germany VS China Taipei, the outcome is unpredictable. After all, both sides are short of core players, and whoever loses or wins is likely, but it seems that the German team still has a slight advantage.

At 19:00 in the evening, the Chinese and Japanese teams appeared again. Among them, Japan’s opponent was Slovakia, and the latter was basically out of the question, while everyone was mainly concerned about another game-Guoping VS France.

Friends who are concerned about table tennis know that last year and this year, French players created great pressure on us, among which Alex defeated Fan Zhendong and Liang Jingkun, Yuan Jianan defeated Manyu Wang, and Felix almost overthrew Malone. Veteran Simon eliminated Xu Xin in the World Table Tennis Championships, and his overall strength was stronger than all the opponents that Guoping met in this competition. Be careful!

So who can have the last laugh in these next confrontations and win more points for themselves to hit the championship and medals? Suspense still exists, let’s wait and see: Come on, China!

On December 6, 2023, the table tennis mixed team World Cup continued, and the second stage started. After the six rounds of round robin, the title was decided. The Japanese won 8-0, easily defeating China Taipei without Lin Yunru and Zheng Yijing. This result was as expected. As soon as the young teenager Yoshiyama Liao made his debut, Zhang Benzhi and/or Hayata Hina played in the first set of mixed doubles.

In the second stage, eight teams competed for the championship, and the contest between China, Japan and South Korea became the focus of attention of outside fans. In addition, the French team could not be ignored. Japan lost suspense in the first round against Taipei, China, so there was a big gap between the two teams. The Japanese team was the main lineup, and many famous players from Taipei, China, were absent. Only Chen Siyu was ok.

Japan is the main opponent of Guoping in this competition, led by Zhang Benzhihe and Hayata Hina, as well as Yukuke Inoguchi, Zhang Benmihe, Miyuki Hirano, Miyuki Muhara and others. Although Miyoshi Ito didn’t come, on the whole, it is undoubtedly a first-class standard, and Zhang Benzhihe is in good condition. Earlier, Felix was sealed, so we can see the clue, and we really need to pay attention to it.

The situation of China Taipei Team is the opposite. Although it is also a temporary decision to sign up, many famous players are absent, such as Lin Yunru, Chuan Chih Yuan, Gao Chengrui and Zheng Yijing, who are familiar to everyone. These players with good strength have not come over, and Chen Siyu alone is basically hopeless. Being able to enter the second stage is regarded as completing the expected goal. The main thing behind is to train young people and give newcomers more opportunities to play.

In the first set of mixed doubles, Zhang Benzhi and/or Hayata Hina swept Wang Chen 3-0 and/or Chen Yingqian (11-6, 11-5 and 11-5), China Taipei trained newcomers, and Chen Siyu was not arranged to play, so it was understandable to give up this round in advance. In the second set of women’s singles, Hirano Meiyu beat Li Yu 3-0.

In the third set of men’s singles, Yoshiyama Liaoyi defeated Yang Jia ‘an (11-8, 11-8) 2-0, and finally the Japanese beat China Taipei 8-0, winning the first victory in the second stage. This result was in line with expectations. After all, the overall lineup of the China Taipei team was not good, even if it could be played now.

It is worth mentioning that the first show of the second stage of table tennis was held at 19: 30 on December 6th. The opponent was Slovakia with weak comprehensive strength. There was no difficulty in this game, so no matter how the coaching staff arranged it, there was no suspense in winning the game. Many fans predicted that they would win eight games in a row easily, so let’s wait and see, and wish China players excellent results in advance. Come on!

Deep in the Yellow Sea, millions of large yellow croaker grow freely.

Different from the real wild environment, their new home is a 100,000-ton "Guoxin 1", the first in the world. The "happiness of knowing fish" in the intelligent age is no longer a philosophical problem that can only be discussed. Its 17 breeding cabins use various new technologies to simulate the natural environment in which fish swim, and solve many defects of offshore fence culture. It is reported that "Guoxin No.1" produces 3,700 tons of fish a year, which is comparable to Chagan Lake. This is a major ocean project led by Ling Wen, an academician of China Academy of Engineering, during his tenure as vice governor of Shandong Province.

Ling WenAcademician of China Academy of Engineering, Chairman of Shandong Science and Technology Association, and expert in system engineering and energy engineering management. He used to be the deputy governor of Shandong Provincial People’s Government, the chairman of China Shenhua Energy Co., Ltd., the general manager, director and deputy secretary of the party group of National Energy Group.

In April this year, at the 14th China Industry-University-Research Cooperation and Innovation Conference, Ling Wen was awarded the "China Industry-University-Research Cooperation Outstanding Contribution Award". Ling Wen was born in mathematics, from the head of the credit department of Industrial and Commercial Bank of China and the general manager of the National Energy Group in his early years to the vice governor and chairman of the Provincial Association for Science and Technology. For many years, he has devoted himself to solving large-scale engineering management problems by using system science theory, and is a strategic management expert in the fields of system engineering and energy engineering. It is hard to imagine that many cross-border projects, such as the film Love at Zero Latitude, the large-scale symphony concert Yellow River into the Sea, the original Peking Opera Oriental Dagang, and the Yantai Net Red Punch Site Genghai No.1, all came from Ling Wen. In him, there is not only a rational romance, but also a profound thinking of dialectical understanding and transformation of things. This kind of cross-border has the meaning of "never changing from its ancestors".And this "Sect" is both a method and an aim, that is, to promote social development with extensive engineering thinking and ability. It is about scientific spirit, and it is more about personalized creation.。

The improvement of efficiency brings about the improvement of thinking.

At present, science education is endowed with a deep responsibility to transform the world, which is of great enlightenment significance to people’s growth and success. When talking about science education, Ling Wen first pointed out the overall crisis faced by education, saying that "our education is far from matching the national strength". While education is highly valued by the whole society, it has become the value trend of current education to cultivate students’ all-round development in morality, intelligence, physique, beauty and labor, but our evaluation criteria have not been fundamentally changed. "This standard ignores the individuality of people." Ling Wen said.

With the development of society, the labor efficiency is constantly improving. What should the improvement of efficiency bring to education? "It’s personalized. Human beings need to have a certain knowledge reserve, but I think that general education is only a foundation, and its proportion in personal growth should be small. A greater proportion should be reserved for customized education that teaches students in accordance with their aptitude, that is, let every child give full play to his strengths. "In Ling Wen’s view, education is not only about teaching knowledge, but its key influence is to let children find the direction of interest.。

In the past 20 years, China’s science education has been in full swing, and Ling Wen has been promoting science education for many years. In his view, the existing problems are obvious. He pointed out: "The teaching materials, syllabus and curriculum plan of science education have not kept pace with the times. The content of popular science books is still in the form of decades ago, and it is difficult for children to imagine words or pictures. Knowledge such as permutation and combination, spatial analytic geometry, etc. is very difficult for children with weak abstract thinking, but a little more complicated, many children can’t understand it. Now there are actually good scientific and technological means and tools to solve this problem. "

The expressive power of science is rich.Science education needs innovation. What’s new? Ling Wen believes that not only the questions, answers and ideas are new, but more importantly, the forms of expression are also new.. The current technology can completely comb the subject content from beginning to end, and use artificial intelligence to make it into a visual and standardized language. "It may be easy for students to understand revolution and rotation alone, but the revolution and rotation of all kinds of planets and stars in the universe is a relative concept in the solar system and it is not easy to understand together. Now, as long as we put on VR and AR glasses and digitally simulate the operation of the universe, children can understand it instantly. " Ling Wen said that sometimes the form is like a window paper. When the window paper is punctured, the students will be suddenly enlightened.

"I study mathematics. In the past, we proved a theorem, and it took two or three weeks to deduce and prove it on the blackboard. Now it’s very simple. Just use the computer to calculate which letter or coefficient is wrong. Changing one place will automatically generate the result. When we were at school, one of the skills of math teachers was that they could turn their backs on 50 children and draw a standard circle with chalk, but this skill was easily eliminated. " Ling Wen felt that education is the most hopeful field for all mankind. At present, science education should give full play to the advantages of the whole country, enrich popular science forms, and let scientists, artificial intelligence experts and science fiction writers plan digital creative teaching together, so as to improve learning efficiency and give children more time to ask questions and spread their thoughts.

In Ling Wen’s view, the essence of science education is to let children do what they like happily according to their talents. As a teenager, Ling Wen grew up assembling small radios, small semiconductors and small airplane models. "At that time, we often went to the surrounding May 7th factory for internships. When we found that the motor we made could really generate electricity, this excitement was very encouraging," he said.Cultivating hands-on ability from an early age is of great significance for cultivating scientific sentiment and solving major engineering problems in the future. Therefore, for science education, science, technology and engineering need to be popularized.。

During his tenure as vice governor in charge of science and technology, Ling Wen paid close attention to science education. He asked all departmental leading cadres of the Provincial Science and Technology Department, the Provincial Academy of Sciences, the Provincial Academy of Social Sciences and the Provincial Association for Science and Technology to give lectures on popular science in primary and secondary schools every year. A few years ago, the scientific quality level of citizens in Shandong Province did not reach the national average. With the joint development with the national education field, it has been greatly improved by the end of 2022. In his eyes, academicians should go among primary and secondary school students. "No matter how high your scientific achievements are, it is very worthwhile for academicians to give lectures to children, and I can feel happiness from them. Because it is a matter of infinite merit to really plant a seed of the future in children’s hearts, let them learn and love science from primary schools, and finally be able to talk about and use science. "

In September this year’s popular science week, Ling Wen told children about magnetic levitation and the spirit of scientists in the Shandong Science and Technology Hall. When it comes to the story that Guo Yonghuai and his guards, the meritorious service of "two bombs and one satellite", were unfortunately burnt because they tried their best to protect confidential documents when the plane crashed, the children cried. "The spirit of scientists is very important for science education, so we must combine patriotism with the ideal of future life." What moved him was that after the lecture, the children wrote letters and painted pictures of their own feelings and experiences to him, and more than 100 copies were full of sincerity.

Engineering thinking gives birth to new machines in crisis.

It has been more than one hundred years since "Mr. De" and "Mr. Sai" were put forward. Serving the country scientifically is great and passionate. As a system engineering expert with strategic thinking, Ling Wen has been thinking dialectically and calmly about it.

"The purpose of scientific research is to discover laws, and technology is to find tricks with scientific theories. Only when engineers apply scientific discoveries and technical tricks to production and large-scale activities to transform the world can the objective world be truly changed." He believes that scientific discoveries are of course important, even beautiful, but our aim is to form productive forces and then change the world.In the fierce international competition, we should go ahead and balance the relationship between science, technology and engineering, that is, we should handle the relationship between basic research, applied research and large-scale engineering application.。

In early 2020, the COVID-19 epidemic suddenly broke out. Resources are scarce everywhere, and what is lacking most is protective clothing. Ling Wenzheng, then vice governor of Shandong Province, was in charge of resuming work and production, which was a close call and the situation was urgent. "Our task is to hand over 850 pieces of protective clothing to the central government every day, but the province can only produce 650 pieces every day. There is a lack of workers and materials. " In order to isolate the virus, the most important process of protective clothing is to use a laminating machine to seal the adhesive, so as to enhance the isolation performance of protective clothing, and finally through the ethylene oxide cabinet disinfection, in order to really produce.

Under great pressure, Ling Wen went to Zaozhuang Kangli Medical Device Technology Co., Ltd. for investigation, found a workshop director with the most experience in layering machine operation, and asked her how long it would take to train a skilled layering machine worker. The director said, ten years. Hearing this answer, Ling Wen was startled at first, and then he asked the director to demonstrate it again, and then he got on the computer in person, and finished the layering link with his hands, eyes and feet. "Am I qualified?" Ling Wen asked. After reading it, the director said, "The eye of the needle is pressed, and it is barely qualified, but the stitch is crooked."

Ling Wen said that this is his first time to use the layering machine. Whether it is beautiful or not is not his purpose. His purpose is to judge how long it will take to train a qualified layering machine worker and how to achieve the production index of protective clothing. "In this way, it will be simple. There are more than 140 vocational schools in Shandong Province. We have found about 3,000 vocational high school students with strong hands-on ability to immediately train and take up their posts. The problems of workers will be solved immediately and the production capacity will come up at once."

The length of the batten required for a protective suit is 11.6 meters. In the face of the shortage of layering, Ling Wensi examines how to reduce its use length. Through observation, it was found that the practical performance of the seams of protective clothing such as "pinching waist" and "dovetail" was not high, so Ling Wen immediately decided to reform the cutting technology and try to make the most protective clothing with the least layering. In practice, the service length of a protective clothing batten has been reduced from 11.6 meters to 6.3 meters. At the critical moment, a new technology was born.

There is an important process before the protective clothing is delivered to the doctor, that is, sterilization with ethylene oxide cabinet. At that time, the ethylene oxide disinfection cabinets produced by the national protective clothing enterprises were "pitiful". "To sterilize, must we use the ethylene oxide cabinet produced by protective clothing enterprises?" Ling Wen used his quick wits to set aside the established conditions and decided to look for ethylene oxide cabinet manufacturers in other fields. "Because of this opportunity, we caught two’ big fish’, Weigao Medical Equipment Co., Ltd. and Dishang Group Co., Ltd. located in Weihai."

Make something out of nothing. Less than a week later, a new factory was born in the suburbs of Weihai. Integrating the sterilization cabinets of Weigao Group and the capabilities of textile women workers of Dishang Group, this new factory can produce 65,000 pieces of protective clothing in one day. Ling Wen said that telling stories about the birth of new machines in this series of crises is to emphasize the importance of scientific literacy and engineering ability for people to solve problems, and education needs to focus on cultivating students’ thinking ability in this respect. "Only when we have established a certain logical thinking, will we take the initiative to ponder the whole story and exert our creativity."Of course, it is not arbitrary to transform and create things. We should put engineering problems into the interaction and function of several elements of the whole system to understand and form an open and stable structure. This engineering thinking is the basis for solving complex problems.. When asked what are the core elements of engineering thinking, Ling Wen emphasized that solving engineering problems means following goal orientation, result orientation and problem orientation.

On the basis of respecting the law, it is widely crossed and integrated.

No matter the growth of individuals or the progress of mankind as a whole, problems and hopes appear alternately. Scientific literacy and engineering thinking can help us mobilize resources, give full play to our imagination and create a better future.. To reach this bright future, Ling Wen said, children must be encouraged to do what they like and are good at. This is the law of education, and what is more important above this law is extensive intersection and integration.

Recalling college days, Ling Wen was deeply happy. At that time, he could not only concentrate on studying professional knowledge, but also extensively and freely study art courses such as western music history and western art history. Every week, he would go to a symphony concert with three or five friends. Some time ago, he once suggested to Liao Changyong, a baritone singer and president of Shanghai Conservatory of Music, that he wanted to offer two courses, one for engineering students and the other for art students, so that they could understand and integrate with each other.

The transformative power brought by cross-border thinking is enormous. In recent years, Ling Wen has participated in many projects, such as building photovoltaic integration, magnetic levitation power equipment, marine pasture, clean and low-carbon coal projects and so on. "Our other team is currently promoting the research and development of BIPV buildings. In order to make a building generate electricity, photovoltaic panels can be hung on the facade of the building. This project is very simple, but its premise is that there must be a building, which is called BAPV, and BA is BuildingAttached, an annex building. Let’s further develop our imagination and turn A into I, that is, Integration and fusion. If the photovoltaic building is integrated, the photovoltaic panel itself is the building material of the facade, which can be wind-proof, waterproof, dustproof, earthquake-resistant and thermal insulation. Why not? " Ling Wen said that this technology is quite subversive, because building integration alone accounts for about 50% of the country’s carbon emissions. It is estimated that a BIPV building can basically reduce energy consumption by 30%.

"All construction machinery products, in order to reduce the wear and tear of parts caused by friction, usually choose to use special bearings or add oil to bearings. The magnetic levitation power equipment we are developing can not only ensure no contact friction, less energy loss, but also realize high-speed rotation of machinery. " High speed means high efficiency. Ling Wen emphasized that to promote the emergence of these subversive technologies, we should not only master the knowledge of science, technology and engineering, but also respect the law of development of things.

China is rich in marine resources and has broad prospects. In recent years, in order to accelerate the transformation and upgrading of the fishery industry, Shandong has taken promoting the construction of marine pastures as a powerful starting point for developing the marine economy and building a strong marine province. At present, there are 44 national marine pastures in the province, accounting for 40% of the country. Ling Wen said that there are great defects in the traditional way of raising fish. Piling, casting nets and throwing seedlings in the offshore area are people-centered and cultured according to people’s ideas. He laughed and said, "Have we ever thought about how fish feel? Fish have their own growth laws. Migratory birds fly thousands or even tens of thousands of kilometers, and so do fish. " In order to promote the development of fishery in the digital age, Ling Wen presided over the research and development of the "Guoxin No.1" aquaculture ship project. The fish tank carried by this project uses deep-sea water sources to change water 18 times a day, and the salinity, temperature, pressure, electrolyte and other indicators in the tank are consistent with the deep-sea environment. In such a space, the growth density of fish can be ten times higher than that of the outside world.

Ling Wen said that engineering problems are not one aspect or a local problem, but we should consciously and fully recognize the complexity of things, so as to identify the essence of things and the harmonious relationship with the surrounding world, and solve them according to the law on the basis of understanding nature, society and human thinking. In this process, it already includes scientific discovery, technical know-how and engineering realization. “In people’s traditional ideas, scientists’ status’ is the highest. But if I can define it, I would rather call the practitioners in these three fields scientists, technologists and engineers, who are equally important.. The integration of science, technology and engineering is the prerequisite for human beings to liberate productive forces, implement high-quality development, and develop scientific, practical and economical engineering and products.

凌文强调，要按照习近平总书记对战略科学家的要求，培养科技人才跨学科、跨领域的判断力、理解力和领导力，善于将自然科学和社会科学相融合，善于把科学、技术和工程相融合，善于把基础研究、应用研究和大规模工程实践相融合。“一定要鼓励跨界创新，即便在跨界过程中暂时出现失误也没关系，只要秉持严谨的科学精神，相互交流、相互促进，就可以奔赴我们想要的未来。”

江河入海。科学、技术、工程三个不同的支流，在广义上有一个共同的目标，即推动社会发展。辨析凌文解决问题的方法论，科学、技术、工程从来不是孤立存在，而是相伴而生。当下，事物的边界逐渐模糊，关联愈加无序，凌文的广阔视野和发散性思维，以及他所提出的教育观点，或许可以成为一种清晰的方式，给教育以考量。
