It is said that Japanese sitting posture originated in ancient China. The reason why the ancient people in China chose this uncomfortable posture to die is not because the ancient people in China took it hard and deliberately tortured themselves, but because of the clothes at that time. Today's pants were not called pants in ancient times, but called shin clothes, which means legs. A shin suit is a dress worn on the leg. Generally speaking, over-the-knee clothing is probably equivalent to today's stockings. The biggest feature of this kind of shin garment is that it is covered with one leg and covered with two legs. The key is that it has no crotch, and the skirt needs to be worn outside the calf clothes. This is why China chose to kneel in ancient times.
This ancient tradition has long been abandoned by us. On the contrary, in Japan, this tradition has been preserved. This is also the magic of the Japanese nation. People lag behind others in their studies. After studying, people will improve themselves according to their own national conditions and always adhere to the spirit that this is a national need.
Japanese always kneeling is a double-edged sword, which has some disadvantages and many benefits. Sitting on the ankle when kneeling can relieve the stiffness of the ankle and enhance the mobility of the plantar joint, which is good for the plantar joint. In addition, kneeling for a long time helps to form a correct arch of the foot and prevent and improve symptoms such as flat feet and high arches. When kneeling, the upper body is in a tight state, which is conducive to promoting gastrointestinal peristalsis, relieving stomach fullness and improving digestive system. When kneeling, the legs are relaxed and don't have to exert all the time, which helps the blood circulation of the lower body, eliminates leg fatigue and prevents arteriosclerosis.
I have to say that kneeling, with a strong sense of physical balance, is conducive to stabilizing people's emotions and reducing psychological pressure.
