Reporter Jin Cuo reports On October 31st, local time, Song Kai, the new president of China Football Association, appeared at the AFC Annual Awards Ceremony, which was his first visit since he took office. Song Kai’s move hoped to restart China’s football diplomacy and open up the situation.

In January this year, Du Zhaocai, then vice-chairman and secretary of the Party Committee of the Football Association, was elected as a director of FIFA, with 18 votes at the bottom, and was unable to be re-elected. Due to the special regulations of the AFC (only one election was allowed), China Football was "aphasia" in the executive committee of the highest institution of the AFC for the first time.

Subsequently, the chairmen and vice-chairmen of the 16 committees under the AFC were adjusted, and no one in the China Football Association was elected.

However, according to the current "status" of China football, whether it is elected as a director or not has little influence, because even when Zhang Jian and Du Zhaocai were directors, it didn’t bring much help to China football. Even when Du Zhaocai was the chairman of the arbitration committee, China football didn’t even benefit from it, and even suffered a lot when facing the West Asian teams.

In fact, after Zhang Jilong, China’s football diplomacy or "foreign affairs" has been "aphasia". Since then, neither Zhang Jian nor Du Zhaocai has done it, especially Du Zhaocai.

That is to say, after Zhang Jilong’s retirement, China’s football diplomacy has been broken, and the "advantages" of Chen Chengda, Xu Fang and Zhang Jilong, which come down in one continuous strain, are gone.

For Song Kai, there are many things to do after taking over the mess of China Football Association. Youth training and league matches are very important. Judging from his trip to Doha, football diplomacy has not been neglected, or an open attitude.

In the past, some leaders of the Football Association actually did not attach importance to football diplomacy, and some were jealous and some were disdainful of Zhang Jilong’s contribution. Despite Zhang Jilong’s persuasion, Nan Yong "formed an alliance" with Haman, then president of the Asian Football Association, and got a temporary "pleasure" for a football player in China. At that time, he was full of pride. "What football diplomacy is, it’s just interests."

Nan Yong’s words have some truth. "Interests" are indeed fundamental, but connections are also indispensable. Otherwise, there is no channel for "mutual benefit", or why do people believe you? Haman took over at that time, mainly because he was under siege and needed an "exit".

At present, the situation in the AFC is that "the west wind overwhelms the east wind", and for many years, it is very difficult for China football to regain its voice, which Song Kai should be aware of.

In 2013, with the support of Blatter, Salman ascended the presidency of the AFC, and was re-elected for three times since then. The latest term is in 2027. From the current point of view, he has completely controlled the AFC, with no opponents, and his power is better than that of Haman. His secretariat manages almost everything.

Over the years, China’s football diplomacy has been guided by the principle of "following the establishment", which has both advantages and disadvantages. The advantage is that you can sometimes have a sip of soup, but the disadvantage is that you can only have soup.

Previously, China football could not speak because it could not bring "benefits". At that time, many sponsors of the AFC were Japanese and Korean companies, while there were almost no in China; Later, China enterprises participated extensively, but did not express their due "interest demands". They only paid money and did nothing.

For China football, a good opportunity is that an enterprise in China won the business development right of AFC for 8 years (from 2021 to 2028) for 2.4 billion US dollars in 2018. Unfortunately, due to the epidemic, the company lost money for years and was unable to pay the relevant funds, so it had to re-sign the contract and give up most of the benefits. Among them, AFC suffered heavy losses, and China football was also negatively affected.

Since then, China Football Association gave up the right to host the Asian Cup, which also caused dissatisfaction with the Asian Football Association. Among them, Du Zhaocai’s "inaction" was involved.

Therefore, in a certain period of time in the future, China football must regain its "trust" and establish new "contacts" with the world football. Song Kai revealed that the China Football Association is discussing matters related to hosting the World Youth Championship and the World Youth Championship.

In addition, China enterprises that sponsor FIFA and AFC must form a joint force and work closely with the Football Association to maximize the interests of all parties.

During his stay in Doha, Song Kai first met with AFC President Salman and talked with some AFC leaders. Accompanied by Song Kai, Luo Zhao, who has worked in the Foreign Affairs Department of the Football Association for many years, is very familiar with many things about the AFC.

Later on October 30th, local time, Song Kai met Salman on the day he arrived in Doha. Salman congratulated Song Kai on his election as president of China Football Association and reiterated that AFC will continue to cooperate with China Football Association. "I believe that under the leadership of Mr. Song Kai, China football will be promoted to a higher level." Salman said that he was concerned about Song Kai’s remarks. "We have seen the determination of the leadership of the new China Football Association." Song Kai expressed his appreciation and welcome for Salman’s commitment. Salman revealed that the AFC will have a series of concrete development plans to help China’s football continue to develop.

On the 31st, on the day of the AFC Awards Ceremony, Song Kai also had a talk with relevant people of AFC. Although he didn’t have a thorough understanding, he at least laid a foundation. In fact, Zhang Jilong once said that China’s football diplomacy is nothing more than four words: making friends.

Of course, it is whimsical to expect Song Kai to restart football diplomacy at once and even achieve results. After all, he is only a "newcomer", but at least, he has taken the first step. In the future, under the guidance of the policy of "making friends", he will be down-to-earth and may recover lost ground.

　　On May 1st, Beijing time, Ishikawa Kasumi, a famous Japanese table tennis player, posted on social media and officially announced his retirement.

　　"I have decided to retire after the WTT Macau Championship in April. I hope that I can concentrate and go all out in the last game of active service, just like every other game. I am really sorry that I failed to announce my retirement in advance before the game. "

　　"After entering 2023, I feel that every game may be the last game of my table tennis career. I have been carrying this idea and have gone all out to face and enjoy every game. Now, I feel that I have been very satisfied with my table tennis career and have done my best, so I made a decision to retire calmly. "

　　Ishikawa Kasumi

　　"I started to learn to play at the age of 7, and my 23-year ping-pong career has brought me the most valuable experience in my life. Since the London Olympics, I have won medals in three consecutive Olympic Games, won the world championship in mixed doubles, and won five championships in all-Japan championships. In my career, there are many games worth remembering. "

　　"Since I was 14 years old, I have participated in various international competitions as a member of the Japanese national team. For a long time, I have been able to compete at the top level in the world, and many dreams have come true, which makes me very happy and happy."

　　Ishikawa Kasumi also talked about her relationship with China table tennis in her retirement article and expressed her gratitude.

　　"Since middle school, I have been training with coach China at every stage. Along the way, I have met many coaches who have helped me, which is very precious to me. I have also started to contact and absorb China culture and Chinese a little bit. Because I know Chinese, I can communicate with friends and fans in China. I am really happy."

　　"Every time I compete in China, I can feel your enthusiasm. Thank you for the strength and warmth you have always brought me!"

　　"No matter when I am happy to win, or when I am depressed after the game, you will accompany me all the time. I hope that the fans who have watched me play will have a positive attitude in the face of every day in the future, which will make me happy. "

　　Ishikawa Kasumi also looked forward to the future in the article: "From now on, although everything is a new beginning, I will never forget the attitude that the ping-pong spirit has brought me challenges. I will face various challenges and look forward to it. I really appreciate your support all the time!"

　　It is reported that Ishikawa Kasumi’s retirement press conference will be held on May 18th, at which she will share her mental journey with the fans in more detail.

If any word can be the aesthetic benchmark of this year’s fashion circle, it is Cottagecore.

Maybe you are unfamiliar with this uncommon English vocabulary, but you must have seen a lot of fashion trends in Cottagecore style. From show layout to fashion trends to leisure activities, the natural aesthetic style under Cottagecore aesthetics is permeated.

Cottagecore actually comes from an Internet aesthetics, which Wikipedia explains:

"Cottagecore celebrates the return to traditional skills and crafts, such as foraging, baking and pottery, and is related to similar nostalgic aesthetic movements, such as grandmothers, farms and fairies. According to its supporters, Cottagecore’s idea can help satisfy people’s general desire for’ nostalgic longing form’ and get rid of many realistic pressures. "

Many years ago, when the career of designer John Galliano was hit hard, this village farmhouse, which seemed to be in a paradise, became his refuge and enjoyed the pastoral pastoral style of Cottagecore.

Cottagecore is more accurately a comprehensive style of fashion and lifestyle, which may be an atmosphere created by a dress, a trivial matter in daily life or even a photo.

Picnics and camping in this year’s fire are the best proof that Cottagecore style is becoming popular. Doing more outdoor activities and being close to nature may also be an important reason why Cottagecore has become a global fashion trend in a special period.

For fashion, the appearance of Cottagecore has impacted the Normcore style that has been popular in fashion circles for many years. Unlike the sense of high-class that Normcore style advocates like, Cottagecore has a rare simple texture.

They don’t refuse colors, and they don’t have too many collocation skills. Everything seems relaxed and natural. The first brand to set off the craze of Cottagecore in the fashion field is the brand represented by the southern French style, such as Jacquemus, who walked the catwalk in wheat fields and lavender fields.

Jacquemus’s social media self-introduction is full of Cottagecore spirit.

"My name is Simon Porte Jacquemus, I love blue and white, I love stripes, I love the sun, I love fruit, I love poetry, I love Marseille and the 1980s."

Not as exquisite and fashionable as Parisians, the fashion in southern France has a primitive natural flavor. Their greatest romance when making clothes is that they are permeated with printing and handicrafts related to nature everywhere. After polishing, the rough texture is more charming than exquisite things.

The easiest item to get in the Cottagecore style in autumn and winter is the grandma sweater with printing or embroidery, and generally there are various flower patterns embroidered on it.

This kind of sweater is generally a heavy knitted fabric, which completely breaks the setting that the sweater is the basic model. The complicated design reveals a warm sense of family craftsmanship, as if it really looks like the sweater knitted by my grandmother when I was a child.

Sweaters are more retro by adding the weaving technique of twisted flowers to the weave. Twisted sweaters are also a very popular sweater trend this year, even if they appear alone, they will be brilliant enough.

Doll collar is also a good choice with thick thread knitting. The same temperament between water-soluble lace and twisted pattern road makes the two complicated designs fit perfectly.

The matching of thick-line needle sweaters is easy and simple. Cottagecore is a kind of retro style to a certain extent. The single items in the old days always have a taste that new things don’t have.

American Cottagecore is more colorful. This popular element from carpet weaving has a strong hippie style in the 1970s. Granny Square was originally a pattern created by disassembling sweaters and socks and weaving them again.

Patterns with strong ethnic customs are matched with bright colors, with a little simplicity and cuteness of farm girls. Cottagecore’s sense of craftsmanship is undoubtedly displayed in Granny Square.

Granny Square appears on bags and hats, which is lighter and more everyday in modern collocation.

Similar to Granny Square, China Baijia cloth often appears in American Vintage, which is also a single product of Cottagecore.

The "old" pursued by Cottagecore is actually an elaborate "imperfection". Too formal fashion always feels too distant, but this "patchwork" fashion makes people feel kind.

Don’t talk too much about the fashion in Copenhagen. Except for the Normcore school represented by Totême, the color aesthetics in Northern Europe is the natural pastoral beauty with Cottagecore.

The fairy tale flavor of Nordic countries, flowers and forests together create their unique color style, without the gray tone of Mo Landi color system, all colors are fresh and bright, and even the heavy coat in autumn and winter has the gentle texture of grandma.

Fashionable girls who go to the market in the countryside wear headscarves and vegetable baskets. They never care about the fashionable conclusion that they can’t wear more than three colors. It is the use of a lot of colors that makes this Cottagecore style lovely and natural.

The essence of Cottagecore fashion is that there is no collocation rule, and they strive to create a relaxed fashion style. You don’t have to think hard about how to match it every day. Flower skirt+flower sweater also has its meaning.

In this era of lying flat all the time, but never without involution, being close to nature and returning to simplicity has become a luxurious lifestyle. This is probably the meaning that Cottagecore aesthetics has become a popular trend, creating the sense of ritual you want in your daily life and wearing. Don’t push, be a Cottagecore girl.

By the way, you can also go home and look through grandma’s closet, which may make your Cottagecore have a different style.

Swimming and fitness, find out!

But do you really know enough about swimming?

As a qualified swimmer, you should not only have some opinions on technical movements, but also know a thing or two about swimming.

If someone asks you: Why is the fourth lane of swimming competition called the champion lane? Are you a little embarrassed that you can’t answer?

OK, today we are going to popularize some knowledge other than swimming skills and movements to help you "practice both inside and outside".

As we all know, the standard pool is 50m, and the semi-standard pool is of course 25m.

The width is 21 meters, while the Olympic World Championships require a width of 25 meters and a water depth of more than 1.8 meters. There are 8 lanes, each with a width of 2.5 meters, and the side lanes are added with 0.5 meters.

Both the standard pool and the semi-standard pool will be used as swimming pools, and the standard pool will be used in the world competition, while the world short-course championship will be held in the semi-standard pool.

The results of short-course swimming competition are faster than those of standard pool competition, because there is a speed blessing of turning and pedaling every 50m.

A soft rope with a pennant will be hung at both ends of the standard swimming pool. Generally, there will be brand words or logo on the flag, and many people may think it is an advertising flag.

In fact, it is called the 5-meter flag, which is set at both ends of the pool 5 meters away from the edge of the pool. Its function is to help backstrokers refer to the distance to the edge.

When you see the 5-meter flag, you will know that you are coming to the edge, and you can prepare to turn around or sprint. It acts as a reference.

Most swimming pools have a long black line at the bottom, which is the lane marking line.

At the bottom of the 50-meter-long pool, the lane marking line is 46 meters, and both ends are 2 meters away from the pool wall; There is a symmetrical horizontal line at both ends, which is 1 meter long, 0.2~0.3 meters wide and perpendicular to it.

The whole standard line is I-shaped, which reminds athletes to adjust their distance and turn around and pedal the pool wall.

The swimsuits and swimming trunks of the top players in the international arena are very expensive. The fiber products made of shark skin swimsuits can effectively reduce drag, and the price started at 5 figures, and then they were banned.

Today’s big brand "technology model" competition swimsuits are also between 3K and 5K, while hundreds of ordinary competition models don’t have much technology content.

Is such an expensive swimsuit because of its good quality and durability? Not really!

On the contrary, the service life of this kind of swimsuit is very short, and it will be invalid after about 10 times. The invalidation here is not broken, but its drag reduction performance and effect are greatly reduced.

The reason why it is expensive is that it can help athletes physically reduce drag in water. Through special materials and design, the resistance can be reduced by 1%-3%. Don’t underestimate this value, which is a matter of life and death in a short-distance race with a decisive victory of 0.01 seconds.

Fans who often watch swimming competitions should find that professional athletes wear two swimming caps.

First of all, the goggles of professional players are worn inside the swimming cap, which can avoid the swimming goggles from drifting into the water when diving.

Wear an extra layer of swimming cap to completely cover the first layer of swimming cap to reduce the resistance between the head and the water.

It says that the standard pool is 50m and 25m, but it will grow a little when the pool is actually built. Because electronic timing is used in professional competitions, it is necessary to install electronic timing boards on the walls of both ends of the pool, and the timing boards are thick, so it is necessary to leave room for installation. After installation, it will be 50m or 25m.

When the goggles are used for a period of time, the anti-fog layer will fail, and many people are troubled by the fog of the goggles in the water.

It’s a waste to get a new one so quickly. Many fans will buy antifogging agents, while professional athletes rely on licking.

There is something called atrial natriuretic peptide. When you swim, your body is squeezed by water, the veins of skin epidermis contract, blood flows back to your heart, the amount of effort increases, and the atrial wall is involved, so atrial muscle cells will release natriuretic peptide.

Atrial natriuretic peptide reaches the kidney through blood circulation, which will increase the generation of urogen, reduce the reabsorption of water by the collecting tube, and finally increase urine.

Therefore, when we are swimming, we often have urgent urination. Please go to the toilet!

Animals excrete in public places!

Most people in China learn to swim from breaststroke, and the initial breaststroke is really easy to learn and get started quickly.

However, the technical requirements of breaststroke in real competitive competition are very high, and there are many doorways in every movement of the wave frog. All professional athletes will tell you that breaststroke is the most difficult to swim.

Comparing the enlightened flat frog with the wave frog, it can be said that they are two completely different systems.

When professional players train, if they swim in line, no one wants to swim first, because it will be easier to swim with the front.

There will be a vortex behind the swimmer in front, and the swimmer in the back can catch the Shun Feng wave and follow the target reference at the same time, so it is more labor-saving to swim.

It’s like a leader in track and field and a broken bike, but my friends behind me, don’t touch my feet, okay?

There is really no need for a coach to get into the water except the initial stage when beginners learn to swim.

When you can’t swim, the coach needs to get into the water to ensure your safety, and at the same time give you a sense of psychological security and take you to experience the interaction with water.

When you start to control in the water, the coach will do the opposite.

Because you can’t observe all the movements of your body in the water, it is not conducive to helping correct mistakes.

At the same time, the coach’s demonstration underwater is not as accurate and clear as that on the shore, and the demonstration on the shore can also let you see clearly what part of yourself is wrong.

So, don’t complain about your coach’s lack of professionalism or professionalism because he doesn’t go into the water. You invited a coach, not an escort.

A few days ago, a fan said very ostentatiously: We change water in the swimming pool every week!

I just laughed and didn’t talk.

Change the water every week, and the boss is afraid to pay for it!

Nowadays, swimming pools have a circulation system, which filters the water outlet, discharges it at the water inlet, and circulates all the time to purify the water quality.

At the same time, regular drug precipitation, bottom absorption, and removal of impurities in water.

When it comes to changing water, it’s good to change it every six months, but it won’t all be changed, half of it will be taken away and half will be changed.

All water changes basically occur in the overhaul of swimming pools or seasonal closure.

Professional swimmers are basically five or five bodies, with long upper body and short lower body.

The basic requirement is that the arm span exceeds the height. The arm is like a boat’s sculls. The longer the arm, the longer the stroke distance, and the better the effectiveness.

Short legs (of course, not really short) can reduce the gravity of lower limbs and make the body better in the water.

Web swimming is a kind of swimming style in which you can kick the butterfly leg underwater without breathing.

A formal Asian Games event, but flipper swimmers didn’t practice flipper swimming from the beginning, and basically swimmers switched to other events to practice.

There are many options for swimmers to change events, such as triathlon, modern pentathlon, fin swimming, water polo and kayaking.

Many fans always complain that the temperature of the heated swimming pool is too low in winter, and they wish it could be more than 30 degrees.

The most suitable temperature of the fitness constant temperature pool is between 24 and 28 degrees. If the water temperature is too high, the body will collapse and the heart burden will increase during exercise, which is not conducive to health.

The water temperature in the swimming pool where professional athletes train will be lower because the exercise intensity is greater.

If you feel cold, don’t stand and chat, and this is not the place to take a bath.

The strength training of swimmers is very important, but it is seldom done.

The types of muscles developed by iron are not the same as those developed by swimming. Simply put, iron for body-building and bodybuilding produces massive hard muscles with great strength, while swimming needs strip soft muscles with better elasticity.

This point can be clearly found when we observe swimmers. They don’t have the big muscles of weightlifters, but they are all strip muscles with better lines.

Swimmers’ strength training is more of a resistance type, such as pulling confrontation exercises such as tensioners.

It is true that practicing swimming in adolescence can increase your height.

During the development of bones, the technical movements of swimming have been lengthening your body, such as the forward extension of freestyle and the forward slide of breaststroke.

Bones promote growth in repeated stretching movements. Similarly, basketball is the same, jumping and stretching.

But the weight loss effect of swimming is very general, and our article also talked about it separately before:

Although you don’t lose weight, the shaping effect is leverage!

For swimming, physical fitness accounts for 20%, and technology accounts for 80%.

Therefore, to learn swimming, we should first practice the technical movements, and then swim faster and faster by improving our physical fitness.

If you only pay attention to the growth of physical fitness and ignore the most fundamental technical movements, then your stage will be very small, your physical fitness will be limited and your skills will be infinite.

Physical fitness can be improved through silly practice, but technical movements can’t be done by swimming all the time.

The common waterline in swimming pools is not only used to separate swimming lanes, but also a designed wave breaker.

The function is to prevent water waves from forming bubbles and turn the swimming pool into a bubble pool.

Swimmers shave their hair, not just under their armpits, but all over.

This is to reduce the resistance in the water, which is said to be 2%. Professional athletes have done their best to reduce the resistance!

Why is the fourth lane the champion lane?

The final lane arrangement of swimming competition is set according to the preliminary or semi-final ranking.

Preliminary ranking: 1 2 3 4 5 6 7 8 corresponding

Lane arrangement: 4 5 3 6 2 7 1 8 lanes

The first place in the preliminaries will compete in lane 4, and the chances of winning the championship are higher, so it is called the championship lane.

1 and 8 are side roads, which will be affected by water waves bouncing back to the pool wall.

The individual medley, whether it is 200m or 400m, is ranked by butterfly and frog.

However, the four events of medley relay are ranked as the butterfly from the frog.

Because you need to consider starting in the water of backstroke.

In competitive swimming competition, triathlon recognized by professional athletes is: 200m butterfly, 400m medley and 1500m freestyle.

The physical energy consumption of these three competitions is very large, which is a limit test for athletes’ physical energy.

The training of these three major athletes is very hard. Here, we applaud veteran Sun Yang!

I tried my best to sum up the above knowledge about swimming for everyone. Maybe you know it, but there are definitely things you don’t know. Knowing more is also convenient for you to pretend … Sorry, it can also make you a more qualified and comprehensive swimmer!

Are you knowledgeable today?

1. Breaststroke-freestyle-backstroke-butterfly

2. freestyle-breaststroke-backstroke-butterfly

Among them: freestyle is the fastest. Breaststroke is best for exercise. In particular, it can shape beautiful leg and waist curves. The butterfly stroke is the most beautiful, like a mermaid. Backstroke is the most energy-saving and suitable for self-help. Hand-stroke to the back and "down" side. Palm down when paddling. Strive for maximum buoyancy and driving force. When the water comes out, the hand is in the shape of a "knife" (that is, the palm of the hand is opposite to the heart of the hand) to minimize the resistance. Legs-kick down and back. When retracted, the thighs and knees are open and the feet jump. (Think of frogs) Coordination-pushing water by hand and pedaling water alternately. Breathing-learning breaststroke, breathing is more difficult to master. Have to experience it several times. When the hand pushes the water downward, the body will float upwards. Take the time to let the head surface and take a breath. Beginners first learn hand posture in shoulder-deep water (the water is too shallow to feel). Lean forward when practicing. Learn to let your hands control the balance of your body. When you find the feeling, pedal your feet gently. You can try to float. At this time, you can try to cooperate with your hands and feet.

Frequently asked questions and answers:
1. Why do I always swim sideways in freestyle? It was straight, but after swimming for a while, it turned 90 degrees!
A: The posture is wrong and the force is not balanced. First, keep in mind that the goal is ahead. Second, when the hand enters the water, it should be in front of the chest, rowed to the chest, and then accelerated backwards to the side of the body to get out of the water. Seen from the side as an S-shaped curve. Third, the force should be balanced when the feet alternately pat down the water and push back the water. Fourth, when the head is swinging sideways to breathe, the direction of the hand entering the water should be kept in a straight line with the body. I think your hand may have changed direction when you swung your head, so you turned.

2, which brother gives a breathing skill? I always choke on water! ! !
A: The most difficult thing for beginners to master breaststroke is breathing.
Breathe out in the "O" shape in the water for three seconds. When your legs are holding water and your feet are close together, your hands should "press" the water to your chest. With these two forces, your head can naturally be lifted out of the water. Take a breath with your mouth immediately, for about a second. Remember, breaststroke breathes with your mouth, not your nose, so as not to choke water. ) at first, you may only be able to lift your head once or twice, and you are hardly in a hurry. But the posture is right, practice a few times more, and naturally you can cooperate with your hands and feet and breathe freely.

3. I am learning to swim recently, but why do I always turn around in the same place and find it difficult to move forward?
A: Moving forward mainly depends on the downward and backward pushing force of the feet. I think your legs only have the power to beat the water down, but not the power to push the water, so you can only move in place.

4. Do you use your hands and feet when swimming? Why can’t the body float?
A: The above two pictures show the hand-foot coordination posture of freestyle and breaststroke. Freestyle: Breathing, paddling and kicking 1: 2: 2 or 1: 2: 4. The second picture shows the breaststroke posture. From the picture, we can see that the human body is changing in a curved way. When swimming, when your feet are open, your hands are put together in a knife shape and stretched forward. At this time, your feet are hard and your hands are labor-saving. When the feet catch water backwards and recover it, the hands are separated to paddle downwards and backwards. At this time, the main force is the hand. So when you swim, you basically feel that your hands and feet alternate, not at the same time. Many beginners swim with their hands open and their feet open, and then their hands and feet are close together at the same time, which is wrong. It should be done alternately.
5. Is there any trick to holding your breath? It seems very uncomfortable to hold it for a long time.
Answer: When holding your breath, don’t inhale too much oxygen, which is about three-quarters of the maximum inspiratory capacity, and then breathe out when you can’t hold it any longer. When you breathe out, you breathe out a little, then hold it for a while, and then spit again. If you repeat this, you can hold it for a little longer.

A little advice:
Without a good teacher, it is very difficult to learn to fool around in the water alone. Therefore, it is very important to hire a good coach and master the methods.

How to learn to swim the fastest? What’s your experience?
Action structure and technical points
(1) The swimmer is in gliding posture, and his body is close to horizontal. About 80% of the head is submerged in the water, the face is slightly forward, the arms are extended, and the palm is facing the oblique outer side (2). The water catching action begins at about 7~9 inches underwater, and the hands are paddling sideways, and then the exhalation action begins.
(3) The arms have no obvious flexion, and they continue to row to the outside, and the exhalation continues to increase.
(4) When the swimmer’s head starts to move slightly upwards, the elbow joint starts to flex and the upper arm starts to rotate.
(5) When the arms reach the maximum width and the elbows bend about 110 degrees, the high elbow posture is obvious.
(6) Keep the head up, and when the mouth is out of the water, finally exhale. Hands begin to move inward to complete the final propulsion.
(7) When your arms are ready to go backwards, start inhaling, and don’t pull your elbows under the ribs. The knee joint begins to flex and the leg return movement begins.
(8) The mouth is closed, the inhalation is completed, the feet are brought to the buttocks, the elbow joint continues to extend, and the arms continue to move forward.
(9) Leg-returning action continues.
(10) The neck flexes and the head continues to tilt downward. Feet dorsiflexion, legs begin to move backwards, water pushing action, arms returning action.
(11) Push your feet back and start to come together. The swimmer then holds his breath until another stroke begins.
(12) Arms fully extended, hands slightly below the shoulder level, and legs kicking water nearly completed. When the swimmer completes the kick, he concentrates on keeping his body in a straight line. He will keep this gliding posture for a short time, and then when he feels the speed slow down, another arm stroke cycle begins.

A new application test automation method, which can quickly evaluate the experience quality provided by the world’s popular mobile applications.

German technology company recently announced the introduction of enhanced functions for its Nemo device application test suite. The software solution adopts automation technology and artificial intelligence (AI), which gives a powerful boost to wireless service providers and application developers, and can help them quickly evaluate the real interaction between smartphone users and local mobile applications. It is German Technology that provides advanced design and verification solutions, aiming at accelerating innovation and creating a safe and interconnected world.

In the past few years, the number of users who use mobile applications to access digital content and participate in social media platforms and online games has increased significantly worldwide. Compared with the mobile web browser, the local mobile app can provide a tailor-made excellent experience; Therefore, the use of mobile applications has significantly promoted this growth.

Matti Passoja, the head of Nemo wireless solution of De Technology, said: "Service providers and mobile application developers want to know the real experience of end users when they access OTT applications with smartphones connected to cellular networks, and they need a reliable way to verify it. It is DeTech that has created an automated application testing method based on its unique software and hardware technology platform. This method uses real applications, and can accurately understand network performance even in extremely complex and changeable situations. "

It is DeTech that makes full use of artificial intelligence, machine learning (ML) and automation technology, and uses the data captured by local mobile applications (instead of the simulated data flow) to create a brand-new device testing application method.
