Fujian Sports Lottery Center: Lottery players with valid lottery numbers can apply for live viewing if they are interested.

  Recently, the video of the No.4 lottery ball stopping at the top of the slope of the lottery machine and blocking the No.5, No.6 and No.7 lottery balls at the "31 Choose 7" lottery scene of Fujian Sports Lottery triggered a heated discussion on the Internet. On April 24th, the staff of Fujian Sports Lottery Center responded that this phenomenon was accidental after on-site inspection by lottery machine manufacturers. The lottery system was operating normally and the current lottery results were valid. The manufacturer of the lottery machine also responded that there is no abnormality in the lottery machine involved, there is no fault in the equipment operation system, and there is no situation that the lottery is affected by the fault.

  The lottery ball is stuck at the top of the slope.

  Netizens questioned "fraud"

  Webcast video shows that the first three balls fell out and rolled into the exhibition area below the slope, but the fourth ball stopped at the top of the slope and did not roll into the exhibition area. Subsequently, the fifth, sixth and seventh lottery balls were also blocked by the fourth lottery ball and stopped at the top of the slope. On-site notaries announced the winning number according to the dropped ball number.

  According to the lottery announcement, the lottery numbers are 07, 14, 11, 01, 05, 17, 19, and the special number is 28. The sales amount of this period is more than 930,000 yuan. Two bets won the second prize, with a single prize of 18,799 yuan, 19 bets won the third prize, with a single prize of 1,200 yuan, 75 bets won the fourth prize, 200 yuan won the fifth prize in 2207 bets, 20 yuan won the sixth prize in 20729 bets, and 6 yuan won the single prize. The bonus of more than 1.01 million yuan rolled into the next prize pool.

  On April 24, the staff of Fujian Sports Lottery Management Center told Beijing Youth Daily that after the incident, the Sports Lottery Center also contacted the lottery machine manufacturer to check on the spot. At present, the conclusion given by the manufacturer is that this is an accidental phenomenon. "The lottery system itself is operating normally, and the scene is also supervised by notaries. According to the management measures stipulated in the lottery, as long as the lottery ball is shaken out of the mixing bin, this lottery is effective. This time, the ball should have rolled to the exhibition area after it was shaken out. However, due to this accidental scene, the fourth ball stopped there and the balls behind it could not come down, but this did not affect the lottery results. " The staff said that after the incident, the Sports Lottery Center sent the video to the lottery machine manufacturer for the first time. Later, everyone paid more attention to this situation, and the manufacturer should also ask to go to the scene to check the equipment on the spot. What is the specific reason for this accidental phenomenon? Subsequent manufacturers will also issue a written explanation letter, and the Sports Lottery Center will also announce it to the public.

  In response to netizens’ suspicion that "the notary prepared the winning number before the lottery results came out", the above-mentioned staff also said, "If you watch the video carefully, you can find that the lottery ball has stayed on the upper step for a few seconds before falling to the slope. The notary usually sees the lottery ball fall down the steps before preparing the winning number. There is nothing wrong with this. It may be a problem with editing (lens switching), and there is no situation of preparing winning numbers in advance. In addition, our lottery is always open to the public. If the public has doubts about the lottery results, we also welcome everyone to watch and supervise the lottery. "

  In addition, the staff told the reporter of Beiqing Daily that the manufacturer of the lottery machine will maintain it regularly, and the Sports Lottery Center will also inspect the machine before the lottery. Generally, when the lottery machine reaches a certain age, the Sports Lottery Center will replace it. It said that the lottery machine used at the lottery site on April 12 had no problem in operation and was currently in normal use.

  Regular maintenance of lottery machine

  After inspection, there is no fault or abnormality.

  The reporter of Beiqing Daily learned that the manufacturer of the lottery machine is Shanghai Junti Science and Technology Equipment Company. The staff of the company said that the lottery machine at the "31-7" lottery scene of Fujian Sports Lottery on April 12 was a relatively new machine. During the normal service period, there was no such situation that the lottery ball stopped at the top of the slope before the lottery. "This is an accidental phenomenon, not man-made. We have checked on the spot, and there is no problem with the machine and the lottery system. This situation has nothing to do with the lottery machine. "

  Regarding the speculation that netizens questioned the machine failure or the static influence of the lottery machine, the staff of Shanghai Military Sports Science and Technology Equipment Co., Ltd. said that they would carry out regular maintenance, inspection and overhaul of the lottery machine according to regulations to ensure that the lottery machine can operate normally. "At present, what we have learned and seen is that there is no abnormality in this machine, there is no fault in the equipment operation system, and there is no situation that the lottery is affected by the fault."

  Notary before each lottery

  Will check the lottery machine and the ball

  According to public information, "7 out of 31" is a Chinese sports lottery authorized by China Lottery Center and underwritten by Fujian Sports Lottery Distribution Center in its jurisdiction, referred to as Fujian Sports Lottery — 7/31。 The lottery ticket is distributed and sold by computer network system, and the lottery ticket is drawn on TV regularly, and the winning prize is determined according to the number of matching betting numbers and winning numbers.

  In view of the special situation of the "7 out of 31" lottery scene in Fujian Sports Lottery Center on April 12, Beiqing Daily reporter called the customer service of China Sports Lottery. The staff introduced that the relationship between China Sports Lottery Center and Fujian Sports Lottery Center is business guidance, and "7 out of 31" belongs to local gameplay. The lottery situation is mainly handled by Fujian Sports Lottery Center. According to the China Sports Lottery Center, the lottery at that time was normal, but the lottery ball that was shaken out did not roll to the exhibition area, and the ball behind it did not roll down. "Every time the lottery is broadcast live, there will be relevant notaries to supervise the whole process. The winning number is no problem. Fujian Sports Lottery Center also contacted the supplier to analyze the situation afterwards, and tested the lottery machine and related lottery videos. There is really no problem, and the lottery number is true and effective."

  The customer service staff said that under normal circumstances, before each lottery, the notary will check the equipment and the lottery ball, and after confirming that there is no problem, put the lottery ball into the lottery machine and seal it before the lottery. Except the notary, no one else will touch the lottery ball. "If you are interested, you can also apply for a look at the lottery site through China Sports Lottery Network. If you have any questions, you can also consult the on-site staff."

  Yesterday afternoon, the staff of Fujian Sports Bureau also told the reporter of Beiqing Daily that the staff of the bureau were understanding the investigation about the situation of the "31-7" lottery on April 12.

The temperature reached a record high in September, and 2023 may become the hottest year on record.

  According to Xinhua News Agency, CCTV News and other media reports, Copernicus Climate Change Service, the European Union’s climate monitoring agency, said on the 5th that September this year was the hottest September on record, and the global average surface temperature was 16.38 degrees Celsius, 0.93 degrees Celsius higher than the average in the same period from 1991 to 2020, and 0.5 degrees Celsius higher than the previous hottest September, that is, September 2020. 2023 may become the hottest year on record.

  The high temperature weather is spread all over the world mainly because the ocean temperature has been abnormally high and continuous since spring.

  According to Copernicus Climate Change Service, September 2023 is the "most abnormal warm month" since 1940. The global average temperature in this month is 1.75 degrees Celsius higher than that in September from 1850 to 1900 (before industrialization). The earliest data collected by ERA5, a meteorological database in european centre for medium-range weather forecasts, was recorded in 1940.

  The Associated Press quoted Carlo Buontempo, director of Copernicus Climate Change Service Bureau, as saying that the temperature in September this year was "amazing" and "there has never been a month like this in our records".

  According to the report "Global Climate Status" released by the World Meteorological Organization, 2016 is the hottest year on record. Copernicus Climate Change Service predicts that this record will be broken this year.

  The global average temperature from January to September this year was 1.4 degrees Celsius higher than that from 1850 to 1900, 0.52 degrees Celsius higher than that from 1991 to 2020, and 0.05 degrees Celsius higher than that in 2016.

  Buontempo said that this year’s hot weather has spread all over the world, mainly because the ocean temperature has been abnormally high since spring and has not dropped to the usual level in September. He believes that the El Ni? o phenomenon has played a certain role in the high global temperature this year, but the greater impact is the overall warming trend.

  Copernicus Climate Change Service said that in September this year, the average sea surface temperature from 60 degrees north latitude to 60 degrees south latitude reached 20.92 degrees Celsius, the highest in the same period on record, second only to the highest record set in August this year.

  According to the Paris Agreement reached in 2015, all parties will strengthen the global response to the threat of climate change, control the global average temperature increase within 2 degrees Celsius compared with the pre-industrial level, and make efforts to control the temperature increase within 1.5 degrees Celsius.

  There are frequent island fires, and the summer temperatures in many islands are above average.

  At the beginning of September this year, the website of Spain’s Confidential newspaper mentioned in the report that one month after the summer solstice, the Greek islands of Crete, Corfu and Evia caught fire on all sides. The fire destroyed more than 14,000 hectares of land and killed more than 20 people. A few days later, another island caught fire, and this time it was Sicily’s turn. At the same time, on the other side of the globe, Maui Island (located in the Hawaiian Islands) was also burned into ruins. The fire killed 115 people, and with the rescue work, the death toll will rise. Just when Spain thought there would be no more fires this summer, another fire broke out on Tenerife Island, which turned into the worst fire this summer. All fires have one thing in common: they originated from the island. This is unusual. So what are the causes of all these fires?

  Summer temperatures in Tenerife, Hawaii, Sicily and Crete are all above average. However, this is not the only reason for these fires. Experts pointed out that in recent years, fires occurred in dry conditions and also in bad weather conditions.

  Although all these fires seem to be more like a coincidence, scientific observation stations have not observed any coincidence or fixed pattern in the course of several recent fires. Experts pointed out that many meteorological factors may lead to this situation. In the next few months or years, or there will be a study to analyze this in detail.

  On the other hand, Hawaii, Tenerife and Sicily are all volcanic islands, so it is easier to ignite fires to some extent. They themselves have a historic fire mechanism, which depends on their volcanic activity. Another reason is that these islands are rugged, and once a fire breaks out, it is more difficult to put it out. The wind that affects the island is also much stronger than that on the mainland. In addition, in the process of reducing agricultural and forestry production, such as in Hawaii or Canary Islands, the reduction of land management means that the population is highly concentrated in coastal areas, because it is more suitable for developing tourism. However, there is a lack of management inside the island, neither agricultural management nor forestry management. Once a fire breaks out, these areas are easily affected by such disasters.

  Experts point out that there will be many fires in the future, and all kinds of environments will be affected by them, including urban areas, which people thought would be spared more or less. Scientists’ predictions seem to be getting more and more accurate — — The summer of the earth will be shrouded in fire. And the "perfect storm" that brought all this is not accidental. All indications show that climate change is the main reason for the increasingly destructive, frequent, unpredictable and violent fires every year.

In order to make everyone pay attention to themselves, the stars have put together.

  Gao Xixi (Middle)

  Lu Han; Aires

  Wallace Chung

  What are the most lively days of Shanghai International Film Festival? The first two days of the opening ceremony.

  After walking the red carpet at the opening ceremony, most of the stars chose to stay one more day to promote their own films.

  Therefore, these two days are the days with the most film festivals.

  Zhang Ziyi, Jason Wu, Hugh, Zhang Yi, Deng Chao, Wallace Chung, Zhou Yiwei, Gao Xixi, Shao Bing, Lu Han, Shu Qi, Zhang Jiahui, Guan Xiaotong, Hu Jun, Guo Degang … … There are nearly a hundred stars shining on the beach.

  When stars get together, the most important thing is, of course, to find a topic and attract attention. In these two days, no matter how big a star is, he has to make some moves to become the focus.

  Trick 1: Fight for the right time and play the father’s love card.

  Stars: Deng Chao, Yu Baimei, Gao Xixi

  June 16th is Father’s Day, so playing "Father’s Love Card" is a good way to suit the occasion.

  Looking Up, co-directed by Deng Chao and Yu Baimei, held an advanced viewing in Shangxi Theater. There was a long queue in front of the theater one hour in advance.

  After the screening, Yu Baimei explained why he wanted to shoot Looking Up: "My child is over 5 years old, and Deng Chao has two children, one is 8 years old and the other is 5 years old. Like everyone else, we encounter many puzzles in life and can’t solve problems. This movie tells us what we both want to say most as fathers or as sons. "

  The "father-son relationship" here is touching, and Gao Xixi, the director of the film Eight Sons, which will be released this Friday, is even more clever — — Father’s Day is his birthday.

  Liu Duanduan, Shao Bing and Yue Hong, starring in Eight Sons, sang birthday songs with hundreds of fans in the audience to celebrate Gao Dao’s birthday. A video was also broadcast on the scene, recording the scene when Gao Dao’s daughter sang a song to explore the crew of Eight Sons.

  Gao Xixi said frankly: "This film has a very special meaning to me, and it entrusts me with a love and tribute to my hometown red land. In addition, as I told my daughter, we made this film mainly to show it to young people, hoping that they can know more about ‘ Hero ’ These two words also cherish everything today. "

  Trick 2: seize the geographical position and get the maximum diffusion surface through the fan base.

  Stars: Lu Han, Shu Qi

  To say that the most popular star in Shanghai on 16th was Lu Han.

  The sci-fi film "Shanghai Fortress" directed by Huatao Teng and starring Lu Han and Shu Qi held a press conference, and the hotel lobby was full of fans.

  What makes Qianbao reporter curious is that the fans who are waiting in the lobby and holding the sign "Lu Han" consciously give up a passage.

  Is Lu Han going to walk through the lobby and the fans? As a rule, this is unlikely.

  But this day is no ordinary day. At about 1 pm, Lu Han got off a business car and, surrounded by several bodyguards, really came in directly from the lobby. The scene was once very chaotic, but fans or passers-by who took photos and videos at the same time began to spread wildly in social media such as friends circle and Weibo.

  At the press conference, director Huatao Teng first exposed the reasons for choosing Lu Han, two key words — — "juvenile sense" and "fighting righteousness"

  "When the deer first debuted, I took a fancy to his sense of youth at first sight and thought he was Jiang Yang in the movie. Because the preparation period is relatively long, I will start shooting soon after 3 years and go to see him again. He has not forgotten our agreement, and the sense of youth has not diminished. "

  In the movie, Lu Han has been secretly in love with Shu Qi, but he did not dare to confess. Lu Han was ashamed. "We are at war with alien civilizations, and there is no time for secret love.".

  Shu Qi smiled and said, "When I took this play, I asked Teng Dao first. Who is the character Jiang Yang? After learning that it was Lu Han, I thought I could pick it up. ".

  Trick 3: Talk about people and make a measured disclosure.

  Stars: Zhou Yiwei, Wallace Chung, Jason Wu, Darren Wang, Daxun Wei and Peng Yuchang.

  A little breaking news at the press conference is also a common trick for stars to catch their eyes.

  In the movie "Liberation", Zhou Yiwei plays the artillery in the film. He has a loud voice, basically shouts, and is often thirsty, so the set must have a "thermos cup". Wallace Chung recalled that he had worn out several pairs of leather gloves for the crew to complete complex action scenes.

  In The Climbers, where superstars gather, the press conference is the most lively. Because both Jason Wu and Hugh have a lot of fans, there are also many scalpers outside the stadium.

  Jason Wu said that he likes mountain climbing, but because of his leg injury, he hasn’t been there at an altitude of more than 6 thousand meters. In order to shoot The Climbers, he went to the Xuefeng Mountain in Gangshika, Qinghai Province to experience life. It was January, and in the cold winter, he was dismissed because of a cold. After two days’ rest, he wanted to rush to the top, but his body did not allow him to do so.

  The release of the comedy "Great Wish" directed by Yu-sheng Tian, the director of "Former" series, directly made Wang Dalu, Daxun Wei and Peng Yuchang form a "Wish Brothers Group".

  The three men talked to each other, and the golden sentences were frequent, which caused laughter at the scene.

  For example, Darren Wang vomited that Daxun Wei was "too tall to play high school students".

  Daxun Wei responded: "Probably Tian Dao saw that my temperament was outstanding. Thanks to Tian Dao’s trust, I returned to 18 years old."

  For Peng Yuchang, who was lying in bed almost all the time in the movie, Daxun Wei teased him for "acting only with Adam’s apple".

  Not to mention the war of words, the three male hosts also "joined hands", successfully unlocked the classic disco dance steps and the iconic movements of the men’s team in the interactive session, and pushed the atmosphere of the conference to a climax in a hot song and dance and the old square dance.

When the ping-pong ball is hit at supersonic speed …

In animation, Japanese students usually have the power of conan the destroyer, and playing ball always feels like a high-tech war.
In reality, can humans play ball games so ferociously?
(All the articles are professional, please don’t imitate them at home.)
Although it is impossible to rely on manpower, we can use the power of air and machines, such as the "vacuum table tennis cannon."
A cannon is actually more like a pipe. When a cannon is fired, the speed of the accelerated table tennis can reach 450km/h, which is about one third of the speed of sound.
At this time, the table tennis directly crashed into the coke with air pressure, and this can was like a punch in the abdomen:
What if the speed of table tennis is increased to supersonic speed? Will it be more powerful? In fact, mythbusters, a well-known popular science team, made a similar attempt many years ago.
According to their test, the average adult can hit the ball at a speed of about 112.6 kilometers per hour after swinging.The speed of sound is 1224 kilometers per hour, which is an insurmountable gap.
Unless, of course, the table tennis player is a machine.
After several attempts, they successfully increased the speed of table tennis to 730 kilometers per hour by pressure jet, which directly penetrated the 2.5 cm cardboard, but this speed is still far from the speed of sound.
At this time, the "vacuum ping-pong cannon" appeared.
To put it simply, this device is to put a ping-pong ball at one end of a pipe and then seal both ends of the pipe:
Then, the air in the pipeline is drained to make it enter a vacuum state, and then the seal at one end is punctured, and the air will rush in wildly and then fill the vacuum space.
At this time, the table tennis in the middle will be pushed by the air and move to the other side at high speed, and there is no air obstacle on the road.
The power of this kind of vacuum cannon has been improved remarkably. With only a 1.8-meter-long pipe, the ejection speed of table tennis has reached 600 kilometers per hour.
And if we add a pressure chamber to the vacuum cannon and increase the length of the barrel, the speed will be upgraded again.
(Image from Purdue University of Technology)
But it is not as long as possible. Once the barrel was lengthened to 47 meters:
The acceleration effect is different. After firing, the human eye can’t see the ball moving at all, and the ball disappears directly:
However, when the table tennis flies out of the barrel, it has been squeezed out of the ball by resistance.
In the end, the barrel was reserved for 6 meters, which not only ensured the integrity of the ball, but also reached the speed of 1770 kilometers per hour, which properly exceeded the speed of sound.
So, "What destructive power will the vacuum table tennis cannon have now?The researchers set the shooting target-a thick pig elbow.
Fill in table tennis, adjust the pressure, pump out the air and fire!
Table tennis hit the surface of the pork completely, and the elbow suffered great damage. A round wound immediately appeared on the epidermis:
But the injury doesn’t stop there. Under this wound, there is a wound with a depth of nearly 4 cm:
However, this wave of injuries is difficult to subdivide how much table tennis can account for. After all, it broke at the moment it touched pork, and the subsequent injuries were more like air cannons.
But overall, it smells like animation.
There are still many people who use "table tennis vacuum cannons" to sabotage. They have chosen all kinds of strange targets for testing.
Mark French, a professor at Purdue Institute of Technology, and his students, combined a supersonic table tennis cannon with a pressure chamber and a vacuum gun, which is said to be faster than an F-16 fighter.
(All the articles are professional, please don’t imitate them at home.)
In the face of this kind of attack, the table tennis bat can do nothing at all and is directly penetrated:
When you hit a tape, it’s like hitting tofu:
Not only did the tape break a hole, but the carton at the back also broke a hole:
Carton:
The most cruel thing is to play a row of cans and disappear in an instant:
Look at the injury of cans, it should be destroyed by the group:
With such destructive power, it is no wonder that the professor emphasized on the whiteboard that he is a professional team and advised others not to try it at home.
Bruce Yeany, a physics teacher, also tried to play cans. From the effect point of view, he used more power:
But when he bombarded the watermelon, he encountered a problem, that is, the quality of table tennis was too small after all, and it broke directly in front of the watermelon:
Is this the only survivor in the table tennis test?
However, watermelon didn’t laugh for long. The teacher unhurriedly increased the weight of table tennis, not much, just filled it with water:
Now, watermelon immediately becomes watermelon juice:
Watermelon: Can’t you afford to play?
However, the most extravagant way to play table tennis vacuum cannon comes from anchors Dianna Cowern and Brandon.They aimed a cannon at an iPhone 11 Pro worth more than 6700 yuan:
How can I put it? The moment when table tennis hits the mobile phone is quite artistic. Maybe this is the happiness of being rich.

This is one of the reasons why the per capita consumption of resources in the United States ranks first in the world. Just like PINKRAY  Jr. knows what it’s like to have three tones a year, he wastes a lot of experimental props, sees foreign children doing domino experiments on TV, and there are a lot of things on the Internet that are similar to putting people into shredders.

# Article First Challenge # Will new energy vehicles replace fuel vehicles?

Different people have different views on whether new energy vehicles will replace fuel vehicles.

Wang Qing, deputy director of Market Economy Research Institute of the State Council Development Research Center, predicted that by 2025, the annual sales volume of new energy vehicles in China will reach about 17 million, and by 2030, the market share of new energy vehicles will exceed 90%. This means that in the next decade, the sales and influence of new energy vehicles will increase rapidly.

On the other hand, new energy vehicles and fuel vehicles have their own application scenarios. In the short term, new energy vehicles may not completely replace fuel vehicles. This is because there are still some problems in new energy vehicles, such as safety, charging and battery life. If these problems are solved, new energy vehicles may further expand their market share.

However, in the long run, it is an inevitable trend for new energy vehicles to replace fuel vehicles. With the continuous progress of technology and the enhancement of environmental awareness, new energy vehicles will be applied in more fields, including passenger cars and commercial vehicles. At the same time, the policy is also promoting the development of new energy vehicles. For example, some cities have gradually stopped selling fuel vehicles.

To sum up, new energy vehicles may replace fuel vehicles at some point in the future, but this process may take some time. In this process, fuel vehicles and new energy vehicles will

Coexist and compete with each other.

Running, skipping rope, climbing stairs … hurt your knee? Don’t worry about it. Look at the exercise guide for the best of both worlds here.

When it comes to exercise, many people are worried about hurting their knees.

So what kind of exercise hurts the knee the most?

The answer is

Sitting for a long time hurts your knees the most!

Long-term sedentary articular cartilage will gradually lose nutrition and "starve to death"

So exercise properly.

To prolong the life of the knee.

But the premise is to master scientific methods.

Avoid unnecessary damage.

Climb mountains and stairs

Risk of knee injury: ★★★★★★★

When going up the mountain (stairs), your knees will bear about three times your own weight.

When going down the mountain (stairs), the knee will not only bear the impact of the ground, but also increase the wear of the knee.

Therefore, it is not recommended to climb mountains and stairs as daily exercise.

Click on the picture below to see the correct posture of going up and down the stairs.

Key points of climbing without hurting knees:

The center of gravity is slightly forward when going up the mountain and slightly backward when going down the mountain.

Hold the railing to help or use the trekking pole.

Knee injury, good leg first when going upstairs, bad leg first when going downstairs.

Tip: Old people, overweight people and people with knee injuries are best to crawl less. Don’t insist on climbing if your knees are uncomfortable.

rope skipping

Risk of knee injury: ★★★☆☆☆

The risk of skipping rope to knee joint is mainly related to the venue.

Generally, the concrete floor downstairs in a residential area can’t provide an effective buffer for the impact force when skipping rope falls to the ground, and it is easy to hurt the knee for a long time.

Key points of skipping rope without hurting knees:

Choose plastic floor or cement floor to lay plastic mats.

When jumping, keep your feet close together to avoid bending your knees greatly.

The take-off height is 2 cm ~ 4 cm, so as to ensure that the skipping rope just passes through the soles of the feet.

Shake the rope with wrist strength and keep the big arm close to the torso.

jogging

Risk of knee injury: ★★☆☆☆

Jogging rarely causes knee injuries as long as it is not excessive.

A few people with obvious O-leg, X-leg deformity or knee joint disease and overweight should exercise reasonably according to the doctor’s advice.

Key points of running without hurting knees:

Warm up for 5-10 minutes before jogging, and run for 30-60 minutes every day, without paying too much attention to the distance.

Lean forward slightly, swing your arms naturally, and touch the ground with your forefoot.

Keep the speed "breathing, heartbeat is slightly faster but you can talk normally"

Plastic ground and asphalt road are selected for the site, and cement ground is not recommended.

Tip: Treadmill needs to be used with caution. If the setting is unreasonable and the speed is too fast, it is difficult for the average person to keep up with muscle strength and coordination after fatigue, but it is easy to get injured. In addition, the weight is too large, and the injured knee joint should be guided by a doctor.

At the same time, don’t be a "weekend hero" and suddenly go to exercise. Exercise should be gradual, gradually increase the amount, and the weekly increase should not exceed 10%. Don’t be a "weekend hero" and suddenly exercise.

a kind of traditional Chinese shadowboxing (tai chi chuan)

Risk of knee injury: ★★☆☆☆

Some people think that Tai Ji Chuan’s squats like "Ma Bu" will put too much pressure on his knees.

As a matter of fact, many scientific studies actually show that playing Tai Ji Chuan twice a week can not only protect the knee but also relieve psychological stress.

Key points of Tai Chi without hurting knees:

You need to warm up before playing Tai Ji Chuan.

Don’t squat too much in pursuit of beautiful movements.

You need to stand on one foot or rotate your body slowly.

Once knee discomfort occurs, don’t endure it and stop immediately.

Ride a bike

Risk of knee injury: ★★☆☆☆

When riding, people’s weight mainly presses on the seat cushion, and the force on the knees is relatively small, which also helps to strengthen the muscles around the joints.

However, if you ride too hard or take some wrong riding posture habits, it will also have certain health risks to your knees.

Key points of cycling without hurting knees:

Adjust the height of the seat to: when the foot steps on the lowest position, the knee joint slightly bends about 170.

Hold your head high while riding, keeping your knees and toes facing forward.

Keep riding at a constant speed, and don’t suddenly increase the speed by force.

Exert your thigh, and step on the pedal with the first third of the sole of your foot.

Tip: If there is obvious discomfort in front of the knee joint when riding a bicycle, it is necessary to minimize such activities.

Click on the picture below to see the details of riding a bike correctly.

swim

Risk of knee injury: ★☆☆☆☆☆

When swimming, the body is basically parallel to the water surface, and the knee joint is basically free of load, so it is best for the knee joint.

However, patients with knee injuries should avoid breaststroke as much as possible. Water resistance will impact the knee joint when breaststroke kicks, and long-term high-intensity breaststroke may aggravate the symptoms.

Tip: Freestyle and backstroke are more recommended to protect the knee joint.

Can knee pads help maintain your knees?

Many functional knee pads only sell a conceptual thing, and one thing that all functional knee pads do is actually heating. Keeping warm is a very important part of knee joint maintenance, because the joint itself is afraid of wet and cold.

Therefore, normal knee pads have two main functions.

1. Keep the knee warm

2. Increase the stability of joints.

If the functional kneepad is non-invasive to the knee joint, it is actually no problem to use. However, some people may be allergic to drugs for knee pads, so they need to be careful.

Knee pads used in osteoarthritis, the most important function is to keep warm;

The main function of knee pads used in traumatic arthritis is to provide extra stability for joints;

Primary synovitis and gouty arthritis may not be particularly important for the use of knee pads.

point out

1. Don’t rely too much on knee pads.

Long-term dependence will lead to muscle atrophy inside the joint, which is actually more unfavorable for the protection of the whole joint.

Especially for relatively young people, we must not rely too much on knee pads, but should make muscle strength stronger.

2, the temperature must not be too high, not too long.

3. Observe whether there is drug allergy in time.

4. Don’t wear too tight knee pads.

Too tight kneepads can easily lead to blood stasis, resulting in poor blood return, which may lead to thrombotic diseases of lower limbs, which may even be fatal.

What is culture? A good article that never tires of reading.

Reading a lot of books, having a lot of knowledge, having a high degree of education … is completely different from having a culture.

My favorite answer about what culture is is a four-sentence summary by writer Liang Xiaosheng:

Cultivation rooted in the heart,

Consciousness without reminding,

Freedom based on constraints,

Kindness for others.

01

A flight attendant named Judy told an interesting story about Liu Shishi at the Weibo.

Judy often meets all kinds of big coffee and stars because she is a flight attendant and serves on the plane.

But none of these big coffees and starsgive herMake a deep impression.

Until a few days ago, she met Liu Shishi.

that dayLiu Shishi flew first class.

When Judy went to tidy up the first class after the plane landed, she was surprised to find that the quilt on Liu Shishi’s seat was neatly folded.

Judy was shocked at once: "In the past, all the first-class guests huddled their quilts and left under their feet. I didn’t expect the poems to be neatly stacked. I was so touched."

People who fly in first class are usually people of great status, but you see, there are so few people who fold quilts. Occasionally, a flight attendant will be moved for a long time.

02

On May Day, I met a wandering singer when I was shopping with my mother.

After listening to a song, I went over and threw five yuan change into the hat.

But then, my mother’s behavior surprised me.

She went to the hat, crouched down slowly, gently put two coins in the hat, and nodded to the wandering singer with a smile.

My mother didn’t read much. But this moment: I really lost her too much.

Comparing these things, I think of a sentence from Bai Yansong:

"Whether a person has a culture is not based on how high his education is. People with academic qualifications do not necessarily have culture, while those without academic qualifications do not necessarily have no culture. "

Reading a lot of books, having a high diploma, and having education are sometimes completely different.

03

Wu Xiao Xian told another touching story.

Once, he followed the boss to talk about business, and at lunch, he ordered a table in the hotel.

Halfway through the meal, the waiter served a special dish, and the boss said politely, "Thank you, we don’t need any more dishes."

The waiter explained, "This dish is free."

The boss still smiled and replied: "We don’t want it for free, we can’t eat it, it’s a waste."

After the meal, the boss wrapped the leftovers.

On the way back to the company, the boss drove slowly, as if looking at something.

Wu Xiao Xian was wondering when the boss stopped the car, picked up the packaged food, got off the bus and walked over to a beggar, and handed it over with his hands.

What is culture? This is culture. Culture is self-cultivation rooted in the heart.

04

I read another story in People’s Daily.

On the weekend, my nephew followed a Chinese to go fishing in Sydney, Australia.

Every time you cast a net, you always get something.

But every time the net is pulled up, the Chinese always pick it up and throw most of its shrimps and crabs back into the sea.

His nephew was puzzled: "I finally hit it, why throw it back?"

The Chinese replied: "Only fish and shrimp that meet the specified size can be caught."

His nephew said, "No one can care about you on the high seas?"

The Chinese smiled faintly: "Not everything needs to be reminded and urged by others!"

What is culture? This is culture. Culture is consciousness without reminding.

05

What is freedom?

Many people’s understanding is that freedom is to let yourself do what you want freely. But people who think like this don’t know what real freedom is.

Linda, a Chinese-American writer, wrote a book "Worry in the Deep History", which presents the fact that the United States is not only the freest country in the world, but also the least free country in the world.

On one occasion, he accompanied his friends from China to visit the Grand Canyon of the United States.

My friend picked up the coke can and wanted to throw it into the Grand Canyon: "What a pity not to do something in such a deep canyon!" "

LindaStartled, he quickly stopped: "This is illegal."

The freest America in the world is actually full of illiberality:

It is illegal to hold an open wine bottle in the street;It is illegal for parents to slap their children when they cry.It is illegal to even talk about pornographic jokes in the office;……

Many people in China don’t understand why the United States has so many restrictions. In fact, it is precisely because of so many constraints that American freedom has been created.

The philosopher Mill said: "Constraints are the mother of freedom. Personal freedom must be based on not infringing on the freedom of others. "

What is culture? This is culture. Culture is freedom based on constraints.

06

There was a man who taught his disciples to break glass products and put them into garbage bags, and wrote on them with a pen: "There are glass fragments inside, it’s dangerous!" "

In this way, garbage collectors won’t scratch their fingers.

The mineral water bottles after drinking drinks are also emptied and tightened, which is convenient for waste recyclers to collect.

You ask me what is culture? This is culture. Culture is kindness for others.

When going to the toilet, think of the next person who goes to the toilet;When throwing garbage, think of the next garbage collector;No matter what you do, you must think of the next person;……

07

Xia Yan, a dramatist, was in great pain before he died.

The secretary said, "I’ll call the doctor."

Just as he was about to open the door, Xia Yan opened his eyes and said with difficulty, "Not calling, please."

Then he passed out and never woke up.

"Not called, please." Xia Lao changed a word, but touched a building.

Do you know how Liang Qichao died?

He died in a medical accident at Union Medical College Hospital: the doctor cut the left kidney that should have been removed into the right kidney.

Before he died, Liang Qichao did not curse the doctor, but told his family:

"Don’t tell the media, don’t publish. The people have just begun to believe in western medicine. If they know about me, they will inevitably retreat. "

Xia Lao Liang Lao is the truly literate person.

A true cultural person should have four qualities:

Cultivation rooted in the heart;

Consciousness without reminding;

Freedom based on constraints;

Kindness for others.

Think about how often we can have conscious introspection without being reminded by others, and we can think of and help others as much as possible.

Speaking of this, we have to say: "culture is the foundation of the country."

Hero, after reading the article, tell us something.

What is culture? # hanli planner

So what do you think is culture? Tang culture; Song dynasty culture. Cultural history (time and space); Minnan culture; Bashu culture; This is the area; Southwest culture; Fragrant culture; This is an object. Tell you, these things are not culture, in fact, I have an answer in the Book of Changes. What do you mean by educated people? What do you mean by educated people? How wonderful is the word "behind people"?

When the culture of the Tang Dynasty and the Song Dynasty is not humanized, it has nothing to do with the present. In terms of the existence and use of culture, it is no longer a culture only when it is not used. It is as simple as that. Therefore, we say that culture must be slowly accumulated and grown up in life. Is the melting of snow and ice a slow process? It’s so wonderful.

In fact, you don’t know what we understand until you think about it. There will be such guidance and opinions about what the country is, including why we should start such courses in colleges and universities slowly, that is, we want more young people and the power of the new generation to join in. What can build traditional culture together?

Like and pay attention, never get lost.
