CCTV News:Speaking of Hua Tuo, everyone must be familiar with it. It is said that this imperial doctor in the Three Kingdoms period has a wonderful hand to rejuvenate the disease. In the Capital Aerospace Machinery Company under the China Academy of Launch Vehicle Technology, there is also a "doctor Hua Tuo". However, this doctor is not a doctor, but an old technician who repairs machine tools. He is Yang Jingde.

Yang Jingde, born in 1937, is a national senior technician, graduated from Shanghai Aviation Industry School (formerly "East China 250 Technical School"), and is one of the earliest military industry technicians trained in New China. At the age of 18, he was assigned to Nanyuan Aviation Repair Factory, today’s Capital Aerospace Machinery Company, and began to deal with cold machine tools.

Now, Nanyuan Aviation Repair Factory has developed into a base for the batch production and development of missiles and rockets in China. From green to old, Yang Jingde never left. He used his life’s wisdom and years to interpret his persistence in the space dream.

Another kind of "magic doctor": "looking, hearing and asking" to repair machine tools

In the 1950s, China’s space industry was still in its infancy, and the conditions were very difficult. Nanyuan aviation repair shop has only a total of hundreds of equipment, all of which are hand-operated machine tools. Yang Jingde doesn’t even have a desk in her dormitory.

However, Yang Jingde was never afraid of hardships, and especially loved to study hard, seizing every opportunity and time to learn advanced technology. Because of his outstanding performance, he was also sent to learn the maintenance of precision machine tools from Soviet experts. For this reason, he made every effort to cherish this hard-won learning opportunity.

At that time, Yang Jingde, who was very young, was already quite famous in the factory. Years of study and research and tempering on the production line have enabled him to practice a stunt: "looking, smelling, asking and cutting" the equipment like an old Chinese doctor.

The oil on the equipment guide rail is more or less, clear or turbid. Yang Jingde can tell the cause of the fault with his eyes.

He can also "listen" to the fault. A few years ago, a British imported equipment was abnormal. Yang Jingde went to the front of the machine tool, leaned down, listened to the noise of the equipment, and then felt the temperature and rotation frequency of the equipment with his hands. The roar in the workshop was extremely noisy, but it did not affect his judgment at all, and he found the "lesion" in a few times.

What’s more, there is another trick, "sound detection from a distance", which makes everyone have to admire the superb skills of this old technician.

One year, Yang Jingde had just finished gallstone surgery, and one of the equipment in the unit was broken. In order not to affect the production, he walked out of the hospital and went back to the workshop for a day. Until he found the cause of the equipment failure and solved the problem, the young comrades of the rest of the equipment could do it by themselves, and he dragged his tired body home. Who knows that at 9 o’clock in the evening, my colleague called and said that the machine that had just been repaired had broken down again. In desperation, he can only instruct the on-site personnel by telephone remote control: "You put your mobile phone next to the machine and I will listen." He vaguely heard the irregular noise in the roar of the machine.

"You put ‘ Lead screw ’ Clean it and see if there is anything extra. " Yang Jingde said.

After the maintenance master took down the "lead screw", he found that there was indeed something superfluous in it. It was aluminium scrap who wore the ball of the "lead screw", which caused the equipment to malfunction. Clean it and reinstall it. Problem solved!

Lay the foundation for your dream with your aerospace peers.

"On October 1, 1997, I began to enter the stage of re-employment, and the specific work was as follows … …” It can be seen from a yellowed Production Task Record Book that this old technician can retire 19 years ago. At that time, Yang Jingde was famous for his stunts, and many units wanted to hire him. The boss of a company came three times and offered him 5000 yuan a month. One company even said, "The salary is up to you, and you are hired as a consultant, so you don’t have to work."

At that time, the salary of rehiring old experts in the factory was 500 yuan per month. Before retiring, the factory leader only said to Yang Jingde: "The factory can’t live without you." He nodded without hesitation.

"I was trained in the factory. Everything I have is given by the factory. I can’t be ungrateful." Yang Jingde said. Not for fame, not for profit, Yang Jingde is like a rock. This firmness is the infinite loyalty of this old technician to the aerospace industry.

After rehiring, the leader always told Yang Jingde that he didn’t have to come to work every day, so call him if he had any questions. But he is still not at ease, coming every day.

Selfless and earnest attitude, marvelous machine repair technology, Yang Jingde has saved a lot of money and made progress for the factory over the years.

In the summer of 2014, an imported machine tool broke down seriously, and there was no maintenance capacity in China, so it had to return to the country of origin, with a maintenance cost of more than 1.3 million yuan and a cycle of at least 3 months. This is a high-precision machine tool, and no one dares to touch it. Yang Jingde looked at it and said, "It can be repaired!"

As a result, 77-year-old Yang Jingde stooped and got in and out of the equipment every day, sweating and working for 20 days. Finally, the machine tool was repaired with only 150,000 yuan. Yang Jingde not only saved "foreign equipment", but also saved more than one million yuan in maintenance costs for the factory. This shocked the original manufacturers.

In 2015, Yang Jingde was 78 years old. Considering his age, the company leaders were really worried about his physical condition, so they ended their re-employment. However, he is still the same as before, and the unit is responsive and has no words.

The old man who repaired machines walked with the aerospace industry all the way, and every progress of this career condensed his life’s hard work and pursuit. He is a witness and a founder. (Text/Liu Chang)

　　"Golden Sentence" is not the product of the author’s feeding, but the reader’s participation.

　　— — — — — — — — — —

　　Some children often tell me that books are classics, and they are often disappointed after reading them. After reading them for most of the day, they can’t read the "golden sentences" worth underlining and extracting. Or read a "golden sentence" and be attracted by a book, but after reading it, I found that there are too few golden sentences like this in the book, and I feel fooled. I know that many people love this "golden sentence-driven" reading. What I want to say is that this utilitarian reading is not a good way to absorb knowledge and nutrition. Searching for chapters and extracting sentences, swallowing the fragmented golden sentences alive, is not immersed in the overall content, and the efficiency is actually very low, which wastes time and good books and reading.

　　"Golden Sentence" is often a "leap generalization" after a long period of material preparation and solid demonstration. For example, Adorno said: In a mass society that follows the crowd, idolatry is often manipulated in a "pseudo-personalized" way, which hides the standardization and identity of the cultural industry itself. Is this sentence "golden sentence" enough? However, it is not isolated. Only by carefully reading the previous foreshadowing and argumentation can this conclusion be logical and theoretically active. After this process, "Golden Sentence" can enter your knowledge system and become an active thought, which allows you to call freely when writing and support your output. Otherwise, the source is separated, only this sentence is extracted as a golden sentence, and the illusion of memory is formed in the notebook, which will soon become a forgotten "dead dogma."

　　Professor Liu Qing also said: Our traditional academic education emphasizes that knowledge should be systematic, have complete structure and logical connection, etc., while young people prefer rich and fragmented knowledge and feelings, so they like "golden sentences". In my opinion, a more flashing sentence, which appears after the overall discussion, has a context.

　　Without understanding a sentence in the knowledge system and overall outlook, that kind of "golden sentence" can’t "know". Sociologist Andrew Abbott distinguishes between "knowledge" and "knowing". "Knowledge" is a result of "knowing", and the important thing is the process of "knowing". Abbott commented: most of the students I teach think that knowing something is knowing a website. The main mode of their knowledge is to "find". For them, "reading Adam Smith" means looking for five or six sentences that are really important in each chapter. They don’t understand that the rest of Adam Smith’s sentences contain arguments and arguments, which he used to produce and defend the key parts of these students. For students, reading is just browsing outside the internet. It is an exercise to filter out the unimportant idle parts and find out the really important things. They don’t actually believe in ideas, they believe in fragmented content. For them, Smith’s theory is not an argument, but a fixed content.

　　Abbott actually criticized this kind of "golden sentence-driven" reading. A book just wants to sum up a few "central ideas", "paragraphs" and "key conclusions", which can spare me the pain of "reading those idle contents". This kind of filtering and screening, as long as those "fragments of golden sentences" have not actually read or understood a book at all, the golden sentences naturally have not entered the knowledge storage that one can call freely. On the surface, I read a lot of books, but my brain is empty!

　　I have always felt that "golden sentence" is not only the result of the author’s hard argument, but also a kind of reading reward for readers to immerse themselves in a book and suddenly become enlightened after tossing and turning. In other words, "golden sentence" is not the product of the author’s feeding, but the reader’s participation. Enter the author’s theoretical framework, immerse yourself in his logic, read through, read through, read the author’s deep meaning, read the logical connection, read the thought corresponding to reality, and understand a long-standing puzzle, and the "golden sentence" comes out. A "golden sentence" truly deposited in one’s own knowledge system must contain one’s own thoughts in the dialogue. I read Weber’s exposition on tool rationality and value rationality, but I didn’t read it before. But during that time, there were many events in the news that "people were regarded as tools" and "formalism bureaucracy only looked at procedures regardless of human life", and I realized that tools crushed value and realized the golden sentence connotation that "because there is a long chain between their actions and results, their moral consciousness will be blurred, which will lead to moral blindness".

　　Reading is a kind of dialogue and generation, which needs to be immersed. "Golden Sentence" is an ideological reward for immersed reading, not a "essence" that can be extracted separately. That kind of extracted essence, mindless "value", is often just a marketing strategy. A famous scholar talked about the "three laws of bestsellers": first, tell what you already know in a way you don’t know; Second, repeat the statement just now and give some examples; Third, repeat the summary and you will succeed. Those golden sentences about a book, such as chicken soup and sales promotion, are mostly tailored for people who don’t study. They are just "telling what you already know in a way you don’t know", just a truth that you agree with, that you are familiar with and understand, and that’s all.

　　When I study, I have a phobia of golden sentences. It’s all golden sentences. How can I stand it? The golden sentence is a "leap generalization" after a long argument, and it is a wonderful pen to make the finishing point. It’s all golden sentences, which shows that there is no argument and reason at all, and it’s all chicken soup-like, catering to you and clever conclusions. Just like the flashy PPT, it is full of "beautiful words that are nice but vague". It’s more like some fake comments. It sounds like a lot of words, and it seems that there are many golden sentences, and there is nothing but empty parallelism and superficial rhyme. The public opinion field is full of such swindlers. When they encounter something they don’t understand, they can fool them by saying a bunch of "beautiful words", so they are mystifying and euphemistic.

　　I don’t like that kind of "looking for standard answers" reading either. If the contents of the book are regarded as "answers that can be copied", it is still exam-oriented thinking and there is no nutrition. A good book can arouse thinking, and it is the thought agitation brought by that argumentation process that challenges some common sense, inspires some new ideas and brings some wisdom. What is wisdom? If intelligence points to a standard answer, intellectual knowledge is a kind of ability to "turn the answer into a question", which is a kind of advanced literacy, which can push thinking to a higher conceptual level and move towards transparent wisdom in new questions.

　　Yes, the better the book, the more you can’t get the "standard answer" from it, but it can produce many problems, which can help you get rid of the "uncertainty of ignorance", challenge most of the "taken for granted" and "self-evident" hidden in your thinking, and move towards the realm of critical thinking after experiencing "multiple chaos".

　　Mr. He Zhaowu said in "A Record of Going to School": "Reading doesn’t have to have a purpose, and it’s better to have no purpose. Reading is an end in itself. Reading brings inner satisfaction, just like a spiritual roaming. In the eyes of others, it is of no value to travel for a day, but for me, the process itself is the greatest value. " Well, reading is by no means utilitarian, quick-paced, lively and immediate, but I also feel that reading will never fail you, enjoy the process, precipitate thinking, and will always nourish you at some time and somewhere.

　　Zhongxin. com, January 18 th At the end of the year and the beginning of the year, the winter vacation is coming. While everyone is enjoying the holiday, the safety issue cannot be ignored. What are the safety matters that need to be paid attention to when studying in school, practicing practice and traveling during holidays? Yesterday, Weibo, the official of the Information Office of the Ministry of Education, issued the "Safety Guide for College Students’ Winter Holidays", reminding college students to beware of illegal organizations such as pyramid schemes, choose regular recruitment/part-time websites, and pay attention to personal information protection.

　　Detention safety article

　　When staying in school during the holiday, students should know the arrangement of logistics service during the winter vacation in advance, and strengthen the study of safety knowledge such as fire prevention, theft prevention, fraud prevention and food hygiene, and strengthen the awareness of safety prevention.

　　Guard against stealing, robbing and cheating

　　Lock the dormitory doors and windows when you go out, take care of your valuables, and especially don’t lend your documents to others easily. Don’t store a lot of cash or leave valuables in the dormitory or on your body.

　　Prevent problems from not "burning"

　　Pay attention to the safety of electricity use, turn off the power in time when you leave the dormitory, do not go to bed with computers and appliances, do not pull and connect wires in the dormitory, do not use high-power appliances, and do not make a fire in the dormitory to prevent winter fires. Call 119 as soon as possible because of an electric fire.

　　Abide by dormitory management regulations

　　Don’t stay with the opposite sex and foreigners, don’t rent out beds to others, and don’t store flammable and explosive materials.

　　Pay attention to the safety of daily life

　　Keep the dormitory environment clean and tidy, and dry clothes and bedding frequently; Indoor ventilation should be frequent to promote air circulation and prevent diseases. Pay attention to keep warm and cold, exercise diligently, ensure nutrition, avoid overeating and pay attention to food hygiene.

　　Healthy and civilized internet access

　　Rational use of the network, reasonable arrangement of time, not indulging in the network; Beware of online fraud and abide by online ethics; Protect property safety, don’t indulge in online games and video games, and don’t contact or participate in unfamiliar online games, live broadcasts, QQ groups, WeChat groups and post bars.

　　Practice safety article

　　During the holidays, many students choose to find internships, but the peak season of winter internship is also the peak of fraud. At the same time, college students should protect themselves and guard against being cheated.

　　Choose a regular recruitment/part-time website.

　　College students must log on to the official recruitment website and be wary of "employment agencies" and "employment agencies". Before submitting their resumes, they must inquire about the company’s relevant information and judge its authenticity.

　　Pay attention to the protection of personal information

　　Some personal information on your resume need not be too specific, such as mailing address, but should focus on your work experience. Be alert to all kinds of telecom fraud and online fraud, and report to the police in time when problems are found.

　　Beware of illegal organizations such as pyramid schemes.

　　Be alert and stay away from pyramid schemes, which usually have one or more of the following characteristics: when you join the club, you are told that one of your duties is to develop more people; Pay an expensive membership fee; Many people are in high spirits in the workplace. If pyramid schemes are identified, college students should immediately stop working and call the police in time.

　　Take care of your finances

　　When you go out for an internship, you should not carry too much cash with you, leaving only a small amount of pocket money. Generally, you should not give your luggage to someone you don’t know.

　　Choose a regular lodging place.

　　If you want to stay in a hotel or guest house with a business license and regular management, you can give valuables to the service desk for safekeeping, don’t go out alone at night, lock the doors and windows when you sleep, and don’t sleep in a room with strangers.

　　Choose tutoring through formal channels.

　　Looking for tutoring through schools, acquaintances and formal intermediaries, we should not trust small advertisements and other unidentified tutoring information. The first time you go to a student’s home to give a lecture, please be accompanied by your classmates, and then get to know the parents of the students before you can continue on the basis of ensuring safety. When you go out as a tutor, you must tell your classmates the other person’s home address and telephone number, and tell them the time to return to school, in case of other circumstances, you can contact your classmates in time.

　　Travel safety articles

　　The winter vacation is coming, and I believe many college students have arranged travel plans. Although travel is full of novelty, it is inevitable that there will be security problems. Therefore, whether traveling together or going home for the New Year, students must do a good job in safety protection.

　　Don’t put valuables in conspicuous places.

　　When traveling, it is best not to carry a lot of cash and valuables, and the backpack must be placed in a conspicuous field of vision, or given to a companion.

　　Take a legally qualified vehicle.

　　When choosing a chartered car service for travel and tourism, you should choose vehicles and drivers with legal operation qualifications, and don’t take the "black" bus that attracts tourists privately. If you are in doubt about the condition of the vehicle, you can ask the transporter to show relevant certificates. Don’t take an illegal "black" bus because of greed and cheapness.

　　Do not take overloaded and overcrowded vehicles.

　　Don’t go out in vehicles that are overloaded and mixed with passengers and goods. Vehicle overload seriously affects the braking and handling performance of vehicles, and is prone to safety accidents such as brake failure. For your own safety, you must not take chances and take overloaded vehicles because of preferential prices and quick arrival.

　　Minimize going out in bad weather.

　　In winter, freezing, rain and snow are frequent, and the road surface is slippery. Travel should check the weather of the destination in advance, reduce going out in severe weather such as fog, rain and snow, and pay attention to safety.

　　The mobile phone must be kept open.

　　Before leaving school, you must inform the counselor, roommates and parents of your personal whereabouts and contact information, and keep the communication tools open so that you can find out in time and help solve the problem.

　　Beware of overly enthusiastic strangers.

　　Do not trust strangers’ words and deeds, and do not drink or eat strangers’ drinks and food easily; Don’t casually accept strangers’ bags, buy tickets, look after things and other help. For college students who are not deeply involved in the world, it is indispensable to guard against others.

　　Communication security article

　　With the coming of winter vacation, college students need to be alert to high-incidence telecommunication network fraud such as booking fraud, online shopping refund and high-paying recruitment. What are the characteristics of these frauds? Learn with Xiaobian.

　　False booking

　　Criminals use portals to make fake web pages of online booking companies, publish false information such as booking air tickets and train tickets, and lure victims into being fooled by lower fares. Later, he asked for another remittance to commit fraud on the grounds of "incomplete identity information" and "frozen account number".

　　Refund of online shopping goods

　　Criminals took advantage of college students’ online shopping for a large number of goods during the Spring Festival, pretending to be online shop customer service staff to make phone calls or send text messages and falsely claiming that the goods taken by the victims were out of stock and needed a refund, demanding bank card numbers, passwords and other information to commit fraud.

　　High-paying recruitment

　　Criminals take advantage of students’ eagerness to practice during the winter vacation, and recruit online staff such as online shop customer service staff, typists, and people who brush traffic through the Internet with high salaries to commit fraud on the grounds of paying deposits and deposits.

　　Loan installment shopping

　　Criminals send short messages in groups, saying that they can provide loans or purchase goods by installment for those who are short of funds, with low monthly interest rate and no guarantee. Once the victim believes it, the other party will commit fraud in the name of prepaid interest, deposit, etc., and will face high interest if it fails to do so.

　　online game

　　Criminals use online games to buy and sell game coins and equipment. After defrauding players’ trust, players are allowed to send money offline, and they will not trade after they get the money. Criminals post information on the game forum, get the remittance and game account provided by the player, and embezzle it together with the account for a day or two.

　　Tips

　　Beijing, March 5 (Reporter Zhang Xi) On the morning of the 5th Beijing time, the 90th Academy Awards ceremony was held at Dolby Theatre in Los Angeles, USA.

　　　　China people have a very flexible scale for the change of seasons. Someone said, "Ah, the Mid-Autumn Festival has come, and autumn has begun." Others said, "Autumn really begins with the first rain after the Mid-Autumn Festival." Someone also told me: "When the wind from Siberia swept the streets and the fruits and leaves on the trees began to fall in the cold wind, autumn really came."

　　　　However, it is already October, and I have not paid special attention to these phenomena. Due to the lack of accurate explanation of meteorology, I have to try to define the beginning of autumn by myself. Since ancient times, it has been men’s instinct to explain seasonal changes through natural signals. The leaves changed color, the rice ripened, the birds began to change their hair and flew to a warm place for the winter. I am still sensitive to nature, and of course I can judge the change of seasons by some kind of signal given by nature.

　　　　Of all the signals I have observed, the most representative is women’s dress. That’s why I define autumn in Beijing as "when girls start to put on boots". It’s really too hot to wear boots in summer in Beijing. If women barely put it on, they can’t stand it for more than 10 minutes, and it not only makes people feel funny, but also makes the salt excreted by the body rise sharply.

　　　　I have been in Singapore for several years. In that country where I can always sweat profusely, even female parliamentarians and company bosses wear shorts, sleeveless T-shirts and breathable sandals to work. Therefore, boots always attract my attention.

　　　　Boots are always paired with stockings and plaid skirts. I often look at these different landscapes with ecstasy, so I am always laughed at by some kind people. One day, I walked out of Dawanglu subway station in Beijing, and it was about 10 minutes’ walk to my apartment. If there is a girl dressed as I just described and walks past me to take the subway, I will not hesitate to follow her. This may be why, sometimes when I get home, I will find my wife sitting gracefully on the bench in boots, stockings and tartan skirt. Perhaps this is why I always look forward to autumn in Beijing.

　　　　Unfortunately, autumn is not far away when it comes to winter. Winter will make people wrap themselves up like "Zongzi". In my opinion, a thick coat over the knee is one of Beijing women’s favorite clothes in winter. They make women’s curves suddenly disappear and make Beijing look like a city with countless huge, crooked and upright caterpillars. Autumn in Beijing is sweet because it is the last season for people to show their charm before the arrival of the four-month cold winter in Beijing.

Continued content

In this column, I will continue to introduce you to the related content of running.

1.?posture?

Let’s start with the posture. As a "most natural" sport, running hardly involves the cooperation between people and equipment (except running shoes, which will be elaborated in detail), and the running mode can be said to be a skill package brought by human beings, which is embedded in genes as people evolve to walk upright.

Since I became a father, I have watched my daughter fall to the ground, from learning to look up, turn over, crawl, stand, walk to run, and often lament the magic of the creator; At the same time, it is very enlightening to observe the movements of children! For example, if children want to pick up toys on the ground, or move a small stool, they must squat down, take them, and then squat up, instead of bending down and reaching for things on the ground first like adults; Another example is that when a child runs, the heel does not touch the ground first, but the sole touches the ground first.

When children learn to walk, their language communication skills are usually not fully developed, so these basic action patterns are not taught by adults-parents only do some auxiliary work such as help at most.Obviously, these basic movement patterns are "preset programs" that already exist in every child’s brain at birth.After a period of "debugging" and "running-in", children can use these preset programs normally, and the action differences between children are very small.??

Now the field of kinematics has fully paid attention to the value of the research on children’s sports patterns, and formed a special branch of developmental sports, and through some exercises, adults can gradually return to their original source in sports patterns.

2.?core

In the introduction of the last issue, we introduced the importance of posture-because of sitting or standing for a long time in life, and often because of poor sitting or standing posture, some wrong body habits are formed, which leads to "imbalance" in the body, and this "imbalance" destroys the core stability of the human body, so it is easy to compensate in sports and becomes one of the reasons for sports injuries.

In Tiesanluan, most fans are energetic and curious sports enthusiasts, and they are also willing to try new things. I remember that for a while, "practicing the core" was a very fashionable thing in the iron three laps (maybe it still is).

Therefore, all kinds of flat support, sit-ups and abdominal muscle tears are practiced happily, and you must regularly take photos of eight abdominal muscles in front of the mirror to prove the effectiveness of "practicing the core".However, when I returned to these special sports, I found that the previous problems still existed, so I went back to the above process and entered an infinite loop.?

This is the trouble of many iron three people-they are all practicing the core, and few people can tell what the core is, and even fewer people know how to use it.?

Generally speaking, the muscles that control the spine and body posture can be called core muscles.We won’t delve into it here. The body is like a complex but not very reliable engine. Only when all parts are in normal positions can the ideal output power be achieved, and the core function is to ensure that these "parts" can be in normal positions without deviation.

3.?DNS

Go on, running,Running mainly relies on the lower limbs to drive the body forward, and the legs do repeated periodic movements like pistons, while the pelvis is the fulcrum of the movement of the legs. If the fulcrum is not stable, the parts will deviate and the engine will act abnormally.. How to control the stability of the core to ensure the efficient operation of the engine? Here is a concept: dynamic neuromuscular stability (hereinafter referred to as DNS). Excuse me? If you know every word, you don’t know what you’re talking about. In this case, the purpose of my subject (zhuang) and general education (bi) has been achieved, and brackets laugh!?

Get down to business,Simply put, DNS is a technical means to help restore or improve sports ability through the stability of core muscles. Different from the usual methods of simply strengthening the muscle strength of waist and abdomen, DNS mainly controls the coordination of waist and abdomen muscle groups and intra-abdominal pressure through the motor nervous system to achieve the goal of core stability.

The diaphragm and pelvic floor muscles of the human body are like the lid and bottom of a mineral water bottle, and the abdominal wall is the body of this mineral water bottle. When your posture is correct, the diaphragm is opposite to the pelvic floor muscle, and you use abdominal breathing to inhale one breath into the abdominal cavity, which causes the intra-abdominal pressure to rise, just like filling a mineral water bottle with water and tightening the bottle cap. At this time, the structure and state of the bottle are very stable and not easy to deform. As shown in the figure below.

If the posture is bad, such as the pelvis leans forward excessively (many people will deliberately do this to make their chests stand high and their hips become warped), the relative position of the diaphragm and pelvic floor muscles will be destroyed, just like if you squeeze the bottle body of a mineral water bottle into it, even if it is filled with water, the bottle still cannot maintain structural stability. As shown in the figure below.

Through DNS, joints can be located in the best position, so as to obtain the best advantages of sports mechanics, and it is also conducive to the correct excitation of sports muscles. existIn long-distance endurance exercise, the muscle strength or endurance of a single muscle is not the key point. The key to improve exercise efficiency is to coordinate the work between muscles and stimulate them at the right time, and a good posture is a prerequisite for achieving efficient exercise..?

I hope this article will play a role in attracting jade, so that everyone can look at the "core" from another angle. We will talk about running shoes in the next column, so stay tuned.

　　 On the morning of June 22nd, "Beautiful Hebei Red Line — — A delegation from the online media interview activities to commemorate the 95th anniversary of the founding of the Party came to Qiannanyu Village, Jiangshui Town, Xingtai County, Hebei Province. The picture shows the Kangda Exhibition Hall.

　　 Hebei News Network (Reporter Chang Fangyuan) This is a fertile red soil and the greenest place in Taihang Mountain. The development model of "red+green" has turned into the badlands into a green mountain and a barren mountain ditch into an economic ditch. On the morning of June 22nd, "Beautiful Hebei Red Line — — The delegation of the online media interview activities to commemorate the 95th anniversary of the founding of the Party came to Qiannanyu Village, Jiangshui Town, Xingtai County, Hebei Province. The beautiful and rich Qiannanyu made online media reporters praise it.

　　 Qiannanyu is the seat of China People’s Anti-Japanese Military and Political University (hereinafter referred to as "Anti-Japanese University"). On November 4, 1940, Kangda General School was stationed in Jiangshui, Xingtai County, Hebei Province. Since then, it has been running here for three years, and has trained three students, totaling 18,000. Zhu De, Peng Dehuai, Liu Bocheng, Deng Xiaoping, Luo Ruiqing, Teng Daiyuan, He Changgong and other proletarian revolutionaries of the older generation have fought and lived here.

　　 On the morning of June 22nd, "Beautiful Hebei Red Line — — A delegation from the online media interview activities to commemorate the 95th anniversary of the founding of the Party came to Qiannanyu Village, Jiangshui Town, Xingtai County, Hebei Province. The picture shows online media reporters interviewing in Qiannanyu Eco-tourism Zone.

　　 Came to Qiannanyu, "Beautiful Hebei Red Line — — In commemoration of the 95th anniversary of the founding of the People’s Republic of China, the interview group first visited the Kangda Exhibition Hall. Surrounded by green hills and shaded by green trees, the Kangda Exhibition Hall is magnificent and solemn. "Looking at today’s magnificent buildings, it’s hard to imagine the hard conditions here in the past. I wanted to look for the old site of Kangda just now, but I was told by the commentator that there was no remains of the old site of Kangda, because the school building of Kangda in the war years was just a few dilapidated earth-walled grass houses. More often, teachers and students could only struggle and study on the grass and in the ravine. " After the visit, Jing Wong, a reporter from overseas network, felt that in the extremely cruel and arduous war years, groups of anti-big students took up important posts, made outstanding contributions to winning the victory of War of Resistance against Japanese Aggression and even the war of liberation, and showed the revolutionary ancestors’ spirit of hard struggle and the greatness of firm revolutionary belief.

　　 On the morning of June 22nd, "Beautiful Hebei Red Line — — A delegation from the online media interview activities to commemorate the 95th anniversary of the founding of the Party came to Qiannanyu Village, Jiangshui Town, Xingtai County, Hebei Province. The picture shows the scenery of Qiannanyu Village.

　　 Starting from Kangda Exhibition Hall, take a battery car all the way up Panshan Road, and you will come to the entrance of Qiannanyu Eco-tourism Zone. What you see along the road are clean houses with red roofs and white walls, clear streams flowing down, and apple orchards full of fruits … … Entering the tourist area, the terraced fruit trees surrounded by layers of stones are lush, and an asphalt road winds up and shuttles through the intoxicating green. On the hillside, the six characters of "recreating beautiful mountains and rivers" planted by evergreen shrubs stand out against the blue sky and white clouds.

　　 Guo Tianlin, secretary of the Party Committee of Qiannanyu Village, said that Qiannanyu was not the scene before. Qiannanyu, which suffered nine disasters in ten years, was a well-known poor mountain village. In 1963, a catastrophic flood almost destroyed all the mountain vegetation and only a few hundred acres of life-saving fields in the village. Since then, Qiannanyu people have been managing mountains and controlling water for 20 years before they got this piece of green in Taihang Mountain. Today, Qiannanyu has formed a layered greening model of barren hills with "ecological forest wearing a hat, dried fruits wrapped around the waist and small terraces holding the foot". All 8300 mu of barren hills suitable for forest in the village have been afforested, with the forest coverage rate exceeding 90% and the vegetation coverage rate approaching 95%.

　　 More than a decade ago, Qiannanyu people made up their minds to close down polluting enterprises such as mineral processing plants and chemical plants that could bring them considerable economic benefits, and developed a 38-square-kilometer "red" and "green" combined eco-tourism zone by using anti-big red resources and green resources all over the mountain, which received nearly 500,000 tourists in 2015. Forest fruit planting and tourism development, before 2015, the collective income of Nanyu Village was 31.2 million yuan, and the per capita income reached 11,800 yuan.

　　 "Here, the spirit of hard struggle not only stayed in the war years, but is still being carried forward. The beautiful scenery here is not a gift from nature, but comes from people’s efforts. What is even more rare is that a group of scientific and technological leaders like Li Baoguo have emerged here, who can take root in places with difficult conditions and lead farmers to develop. " Dai Yu, a reporter from the People’s Daily Central Kitchen, lamented that in Qiannanyu, the red spirit collided with the green beauty, and Taihang Mountain was being written as a legend.
