　　Health is an inevitable requirement to promote people’s all-round development, and it is also the common pursuit of the broad masses of the people. At present, with the continuous improvement of people’s health awareness, more and more people realize the importance of sports and actively participate in various sports. However, in the process of exercise, many people have done some damage to their bodies due to lack of knowledge and blind pursuit of exercise. This edition invites experts to explain the injuries that are easily overlooked in life.

　　As the saying goes, "A journey of a thousand miles begins with a single step", and ankle health is the foundation of human standing and sports. However, about a quarter of the people in the world are suffering from ankle diseases to varying degrees. However, due to the hidden symptoms of foot diseases, it is easy to be ignored and delay treatment, thus affecting the quality of life.

　　1. Most ankle diseases are acquired.

　　Bipedal is called the second heart of human body, which is very important to human body.

　　Although the ankle is only a small part of our whole body in terms of volume, and the area of joint contact is much smaller than that of knee joint or hip joint, the ankle bears the weight of our whole body, which will inevitably lead to higher local pressure of joints than other joints, and it is more prone to injury.

　　Foot and ankle is an extremely complex structure, including foot and ankle, and foot is divided into three parts: forefoot, middle foot and hind foot. A small ankle part, the bones alone involve tibia, fibula, and tarsal bones 7, metatarsal bones 5 and toe bones 14, a total of 28. It’s more complicated in terms of joints. Besides the ankle joints (tibiofibular joint, tibiofibular joint and talofibular joint) that we all know, there are tarsal joints such as talocalcaneal joint, talocalcaneal joint, calcaneal roll, cuneiform joint, cuneiform roll and cuneiform roll, tarsometatarsal joint, metatarsal joint, metatarsophalangeal joint and interphalangeal joint. From the research field, it includes ankle trauma, podiatry and orthopedics. It should be emphasized that apart from congenital factors, such as congenital clubfoot and flatfoot, most ankle diseases are acquired, such as ankle ligament injury and heel pain.

　　Due to the extremely complex structure of the ankle, many kinds of diseases in each part, and the strength of our whole body in daily life, these factors make our ankle more prone to problems, and the ankle problem is more difficult to treat. Excessive exercise and trauma can cause various ankle diseases, especially ankle sprain, which accounts for 40% of sports injuries. It can be seen that ankle disease is a big problem, and what is most closely related to people, but most easily overlooked, is how to wear shoes.

　　2. Many problems with ankles are related to wearing shoes.

　　Speaking of it, people have been wearing shoes since they learned to walk. Can’t they choose shoes? In fact, most people may not know that many problems with ankles are related to wearing shoes.

　　Bad shoes not only easily cause ligament damage, but also easily lead to many diseases in the ankle. A typical example is that many women who love beauty often wear high heels to cause foot pain. Different heel heights will lead to different forces on the forefoot when walking. The higher the heel, the greater the pressure on the forefoot and the worse the stability when walking, which will cause forefoot pain. At the same time, most of the high-heeled shoes are pointed leather shoes, and when they are worn, they squeeze into the big toe, which is easy to cause the big toe to valgus, which in turn causes the lateral arch of the forefoot of the second to fifth toes to sink, further causing forefoot pain. Overloading the forefoot for a long time will also cause some foot diseases or appearance changes, such as metatarsalgia and Morton’s disease, which are related to wearing high heels for a long time. In addition, the heel of high-heeled shoes is generally thin, which will reduce the stability of the back of the ankle when worn, so it is easy to cause ankle sprain. Therefore, in life, if female friends like to wear high heels very much, it is suggested to choose a high-heeled shoe with low heels and a slightly wider forefoot design. It would be better if we can strengthen the muscle strength of the calf, which will help to increase the stability of walking in high heels.

　　3. What should I pay attention to when choosing shoes?

　　● You can’t have only one pair of sports shoes. What kind of sports shoes should you wear?

　　Although we all know that we should wear sports shoes when exercising. However, it needs to be reminded that no sports shoes can be suitable for all sports. For example, basketball shoes for playing basketball require a thicker sole, a flatter overall, and a higher upper at the back to prevent sprains and slips. Football shoes running on the grass require more flexible ankle movements and lower uppers. The ground where tennis is played is usually hard, which requires shoes to have anti-slip cushioning effect. Jogging, on the other hand, requires slightly lighter jogging shoes with shock-absorbing air cushions. People who exercise regularly must prepare shoes for the corresponding sports.

　　● It is necessary to cut the shoes properly, not to cut the shoes properly.

　　Everyone looks different, and the 28 bones of the ankle are naturally different. It can be said that billions of us can’t find the same feet. To a large extent, the arch of the foot is high and low, and the feet are wide, narrow and fat, all of which need special attention when choosing shoes. For example, people with flat feet have poor cushioning when walking with load, and their feet will hurt when walking too much, so try to choose shoes with raised arch pads. Some people have wide toes, or have eversion, so they should choose loose toes, otherwise it will cause wear between toes, and long-term walking will cause pain. In addition, people with heavy weight should choose elastic shoes when choosing shoes to reduce the impact of walking on the soles of their feet.

　　● Older people choose shoes not as soft as possible.

　　With the increase of age, the fascia and ligament of the ankle will also age, and the bones and joints will also undergo degenerative changes. Compared with young people, the ankles of the elderly are more vulnerable to injury, and the speed of recovery after injury will be much slower than that of young people. Therefore, the elderly should pay more attention to the choice of shoes. A common misconception is that the elderly like to wear soft-soled cloth shoes, and feel that the softer the better. In fact, too soft soles can’t give enough support to the soles of the feet, and at the same time, too soft shoes can’t provide good elastic cushioning, which will increase the damage to the soles of the feet. Old people should choose shoes with sufficient cushioning and good elasticity. The part of the insole that directly contacts the foot surface is also required to be relatively soft and fully fit to the sole of the foot. In addition, if the blood circulation of the soles of the feet of the elderly is poor, they should choose looser shoes. The requirement is not only that there is no squeezing and grinding of the feet when trying on, but also that there is no grinding of the feet when the feet are slightly swollen.

　　● Good-looking and expensive shoes are not necessarily suitable shoes.

　　In modern society, shoes are not only a tool to protect the body from cold, but also an aesthetic requirement and even a symbol of identity. Some shoes are worth several thousand yuan or even ten thousand yuan. However, it needs to be reminded that no matter how beautiful shoes are, you can’t have them if they are not suitable for your feet. Just as many women will find that wearing high heels can cause foot pain, sometimes, expensive shoes are not necessarily suitable shoes. For example, for patients with lateral ankle ligament injury, it is recommended to wear some high-top shoes. This is because a higher upper can provide stability to the ankle joint and reduce the occurrence of sprained ankle. For patients with hallux valgus, when choosing shoes, we should try to reduce the pressure on the forefoot and try to avoid wearing high heels. Similarly, women who often sprain their ankles should wear less high heels, especially those with extremely high heels. Because when wearing high heels, our ankles are in a "plantar flexion" position, which is relatively loose, and thin high heels are not easy to stabilize, which will increase the chance of spraining our ankles.

　　● Don’t wait for the soles to wear out before changing shoes.

　　Although we advocate hard work and simplicity, from the point of view of protecting ankles, don’t wait for the soles to wear out before changing shoes. From the above, I believe everyone already knows that everyone’s feet are different. A pair of suitable shoes needs to have a high fit with your feet. When the sole of a pair of shoes is worn thin, the shape of the shoes changes accordingly. At this time, these shoes are no longer suitable for you and need to be replaced. In life, we often find that a pair of shoes are always worn in a certain part. For example, sometimes, the inside of the heel is worn thin, and other places are fine. In this case, many people are reluctant to change their shoes. But in fact, in layman’s terms, it is this worn-out sole that replaces our feet to bear the damage caused by walking. If it is not replaced in time, it will be our feet that will be damaged next.

　　● Foot pain must not be tolerated, and timely medical treatment is the key.

　　Ankle is a complex structure, and everything can’t be done just by choosing the right shoes. Once there is pain in the foot, you should see an ankle specialist in time. What needs to be understood is that many diseases of the ankle need surgical treatment, and there are still many diseases of the ankle that need standardized rehabilitation training, so I hope everyone will not be careless, so as not to delay the treatment and bring serious consequences.

Text: Talking about Qing said AI Author: Zheng Driving

Recently, according to a number of media reports, there are a lot of news about the transfer of orders blindly ordered by Zhiji LS7 on the idle fish platform. Tan Qing said that AI tried to search for "Zhi Ji LS7 blind subscription transfer", and the results showed that the transfer information came from different regions such as Guangdong, Zhejiang, Hunan and Shanghai, and there were "174 treasures" nationwide.

According to the auto industry’s concern, a seller in Guangzhou issued a document saying: Zhiji LS7 was the top 10,000 in the early stage of listing, and received 5,000 cash subsidies to pick up the car, which can change the name of the car buyer, mobile phone number and vehicle configuration …

It is worth noting that the Zhiji LS7, which is positioned as a "smart pure electric medium and large luxury SUV", was officially launched on February 10th. Although it will not be delivered to the first batch of users until March, blind subscription users have been able to test drive in the official experience store offline for nearly half a month since listing.

Previously, due to the fact that the order quantity of Zhiji LS7 was not bad, according to Zhiji’s official disclosure, it was "successfully broken through 10,000" on February 1. However, there are so many order transfers on the second-hand platform now, which can’t help but make some media start to question. The scheduled quantity of Zhiji may have the possibility of "data flooding". For this matter, I haven’t seen the official position of Zhiji yet.

Then the question is, after all, the first batch of blind booking car owners felt dissatisfied after experiencing Zhiji LS7, and wanted to change hands to find the "receiver"? Or is it that the car owner who booked blindly before was not sincere in buying a car at all, just trying to make a difference?

Why didn’t Zhiji officials stop a large number of blind orders from being transferred?

We all know that cars, as a kind of big consumer goods, buyers are more cautious when they start, and it is actually normal for individual owners to transfer orders blindly or return orders. For example, after the release of G9 in Tucki last year, because the price allocation was too complicated, many blind book owners found that many combinations were not practical and decided to unsubscribe.

Nowadays, a large number of orders are transferred from the blind booking of Zhiji LS7. According to normal logic, it may be that the intended owner is dissatisfied with the car or the price.

Speaking of price, I have to mention the price war initiated by Tesla at the beginning of the year. After Tesla took the lead in price reduction, many luxury new power brands began to follow suit. The biggest price reduction in the world reached 30,000 yuan, and several cars owned by Tucki also reduced their prices by 20,000-36,000 yuan.

Look at Zhiji LS7 again. On December 20th last year, this car was put into pre-sale, and the published price range was 350,000-500,000 yuan. When Zhiji LS7 was officially listed on February 10th this year, the official price was adjusted to 309,800 yuan-459,800 yuan, and both the entry version and the top version were 40,200 yuan cheaper than the pre-sale price.

We can’t know how much gross profit the LS7 car has left, butIn terms of price reduction, compared with other high-end brands, Zhiji officials have given considerable sincerity.At the very least, it is much cheaper than the price expected by many blind book owners.

If there is no problem with the price, we should consider a possibility before praising or criticizing the car itself: some owners who buy Zhiji LS7 are scalper buyers.

Is the transfer of Zhiji LS7 made by a "scalper"? In fact, it is not difficult to speculate.

In fact, it is not always possible for "yellow cattle" to make a difference by changing orders, but it needs "time" to help.

Last year, due to factors such as rising raw material prices and tight supply of spare parts, the production capacity of many brands of new energy vehicles was limited, and everyone generally raised prices and the cycle of picking up cars was greatly extended. For example, Tesla’s price increase is 30,000 to 40,000 yuan, and the space for middlemen to earn the difference is attractive enough.

Under this circumstance, a large number of "scalpers" have appeared in the market to satisfy the psychology of some consumers who want to get a car cheap and early.

"During that time, many of our businesses were cut off by the scalper, and some even rushed into the Tesla direct store. Before the sale, the heel intended to talk to the customer. The scalper came forward and said that he had an order, which not only could pick up the car earlier, but also was cheaper than the Model Y after the price increase." Tan Hong (a pseudonym), a new energy automobile dealer in Zhengzhou, told Tan Qing that AI indicated.

However, as the supply chain and other factors limiting production have been alleviated, Tesla has entered a price reduction cycle, and at this time, the days of scalpers are not good. At the beginning of this year, Tesla took the lead in launching a "price war" in order to rush sales, and other high-end new energy automobile brands followed suit. "Now there is no oil and water, and the scalpers who resell orders have converged a lot."

From this logic point of view, under the background of the current high-end car price reduction, the possibility of "scalper" reselling Zhiji LS7 orders cannot be said to be completely absent, but it may not be high. More importantly, the Zhiji LS7 has not been delivered yet, and the quality of this car has not been verified by the market. If it is not a tight commodity, the "scalper" has no certainty of making a steady profit.

However, the exclusive rights and interests of blind book owners given by Zhiji officials are far higher than the blind book price of 888 yuan. Perhaps it is just seeing the "rich rights and interests" of blind subscribers that they will resell Zhiji LS7 with the mentality of taking a chance.

Judging from the price tag given by the transferor of Zhiji LS7 blind subscription, it is true that the price given by a few sellers is lower than the official blind subscription amount of 888 yuan. If these orders come from scalpers, the business is properly lost.

Some people prefer to transfer orders with blind user rights at a loss, which may indicate that these people are slightly disappointed after seeing the real content of Zhiji LS7 car and are worried about hitting it in their hands., simply transfer at a low price and stop loss in time.

However, because this car has not been listed yet, and some transferors ask for more than the official blind order amount of 888 yuan, these people seem to be suspected of scalping.

Whether the blind order transfer is done by "scalpers" or not,For Zhiji officials, this phenomenon may lead to confusion in the brand pricing system, which is a kind of harm to the brand.

For consumers, some people will be greedy for cheap. If automobile manufacturers allow the phenomenon of order transfer to flood, it may cause transaction risks and damage the rights and interests of car owners.

"The transaction of unofficial sales pre-sale channels is not guaranteed, which is prone to disputes. For example, the seller may go back on his word or temporarily ask for a price increase after the buyer takes a photo." Tan Hong told Tan Qing that AI said.

In fact, the attitude of automobile manufacturers towards "scalpers" reflects the brand power and discourse power of an automobile manufacturer, so many high-end automobile brands are trying to rectify the behavior of "reselling" orders.

Tesla, which was closely watched by scalpers, once issued a "no resale commitment letter", requiring users to promise not to transfer the ownership within one year of picking up the car. Offenders should pay a penalty of 20% of the invoiced price, otherwise the binding account change and super charging will be restricted. Weilai launched the "first owner’s rights and interests", which includes a large number of disguised concessions such as free service upgrades, and the sales contract will also stipulate that once the vehicle is resold, the above rights and interests will automatically expire.

Even BYD has begun to cherish the brand feathers. For example, BYD Song plusdmi orders are not allowed to be renamed, and after the forced transfer of orders, some lifetime warranty policies will be limited.

“For a strong brand, whether it is price increase or price reduction, the official will hold the pricing power.Behind Tesla’s crackdown on scalpers is also its obsession with controlling the price system of new cars. "Tan Hong said.

Looking at Zhiji again, many users who transfer LS7 blind orders claim that their rights and interests will not be affected after the transfer. Why is Zhiji not in a hurry to crack down on the transfer of orders? Do you really care that the price system is messed up?

Sales continue to be sluggish, how to build "China Tesla"?

For Zhiji LS7, it is not a big problem to experience the disturbance of order transfer. After all, the real car has not been delivered yet, and the sales volume is unknown. Let the bullets fly for a while.

However, in the view of talking about AI, many media have all kinds of bad speculations about transferring orders, mainly becauseThe sales performance of the first Chezhiji L7 was poor, and the first shot didn’t start.

Judging from the insurance coverage, the cumulative sales volume of Zhiji L7 last year was only 4,682 units, and the average monthly sales volume was not worth mentioning.

Recently, with the release of LS7, Tamia Liu said that the reasons for the low sales of L7 are not only the products and brands, but also the rhythm of channel laying.

"By December 31 last year, Zhiji had opened 113 offline experience and delivery centers, which is relatively small." Tamia Liu said.

Judging from the soaring sales volume in the world last year, the channel is quite critical for the blessing of new brand sales. From this perspective, Zhiji officially allows blind users to transfer orders, perhaps to make up for the lack of channels.

The channel is actually a heavy asset investment. Once it does not match the sales volume, it will also bring a heavy burden to Zhiji. However, from the background of the company, behind Zhiji stood SAIC and Alibaba, which are the rich second generation in the car industry.

According to Tianyancha APP, on August 1 last year, Zhiji completed the A round of equity financing, and the post-investment valuation reached nearly 30 billion yuan; Recently, a syndicated loan of 5 billion yuan was successfully signed. It is not difficult to see that Zhiji Automobile is still favored by capital.

Obviously, Zhiji, who is backed by SAIC and Ali, is not short of money. Why is the channel layout so cautious? Does SAIC still have reservations about its support for Zhiji?

In the high-end market of new energy, in addition to Zhiji, SAIC also has a Feifan car that focuses on high-level intelligence.

Feifan is also a high-end new energy brand. From the price point of view, its positioning is slightly lower than that of Zhiji, and it belongs to an entry-level luxury brand. What is embarrassing now is that with the price reduction of Zhiji, Feifan and Zhiji brands overlap in the price range, and the internal competition is more obvious.

According to the number of new car compulsory insurance purchases, Feifan brand, which has launched four cars, sold only 250 cars in January this year, down 84.55% and 90.04% respectively from the previous month, which is quite bleak. According to the announcement of SAIC, Zhiji, which was built with heavy money, only sold 507 vehicles in January.

In terms of sales volume, Feifan and Zhiji have a weak presence in the new energy market, which is simply a pair of "Wolong Feng Chu". Since Feifan hasn’t flown yet, the pressure on Tamia Liu and Zhiji won’t be alleviated at all.

Recently, with the release of the LS7 model, Tamia Liu took the opportunity to shout out the sales target for 2023: 45,000 vehicles. Objectively speaking, this goal is not too high.

Regrettably, this high-end brand, once regarded as "No.1 Project" of SAIC, seems to be farther away from the goal of becoming "China Tesla".
