First, the reason for the leg shape of Japanese girls comes from heredity. The Japanese probably carry a lot of leg bending genes. In addition, compared with Europeans and Americans, Japanese people are born with less muscle mass than Europeans and Americans, and the pressure to support their bodies with leg bones is greater, making it easier to bend their legs.
Second, the sitting posture is not correct. If the sitting posture is incorrect, the Japanese will use it in their daily life. In fact, sitting posture is learned from us, which is an ancient practice of Han people. Refueling in the right posture will not lead to leg bending, but not everyone can achieve the standard incorrect posture. After a long time, it will affect the development of bones more or less.
Third, developmental deformity and other issues. In addition to refueling, other sitting postures in daily life also easily affect the development of leg bones. The following are some forces for incorrect sitting posture, because once the leg is deformed or reaches a certain level, it will affect the overall sense of balance. When sitting in a chair, you often have the habit of crossing your legs. Actually, this habit is not good. After a long time, it will also cause scoliosis and varicose meridians.
Fourth, Japan's concept consciousness. Many Japanese girls don't reject these leg shapes, but just feel that they have their own cuteness in aesthetics. Even if they find that their legs have changed in the direction of O-legs, they will not correct or correct them. In life, some people will also do the posture of the inner eight in those cartoons, which will also affect the occurrence of leg bending in the long run.
Fifth, Japan thinks this is individuality. When you are old, you are prone to joint pain and even affect walking. In addition, there are aesthetic reasons. Japanese think tiger teeth are delicious and cute, and orthodontics is expensive. In addition, orthodontics will wear braces for a long time, which will affect the face value, so many Japanese people have a negative attitude towards orthodontics.
Different nations and countries have different aesthetics, but they don't like it. We shouldn't laugh at those aesthetic styles that we don't like at will. This is a matter of politeness and self-cultivation.
