There is a depression in the medial and lateral sides of the knee, and the lateral depression is the nose point of the calf. It is an acupuncture point on the stomach meridian, where qi and blood are abundant and it is an acupuncture point for strengthening the body. Kneeling posture is precisely because the nose of the calf on the knee is opened, which makes the blood in the body drop. When it is transported to the knee, there is more fresh blood on the knee, which naturally lubricates the rusty knee joint and reduces the wear of the knee joint. Many elderly people often suffer from diseases such as hyperosteogeny of knee joint and hydronephrosis, and it is also because qi and blood cannot flow to the lower body and knees, which leads to knee joint injury.

Traditional Chinese medicine often says that "the general principle does not hurt, but the pain will not work". Kneeling to get through the qi and blood is like lubricating the knee, which not only facilitates the action, but also relieves the pain. A damaged knee joint is like an aging car. When the damaged parts are adequately lubricated, the car can run smoothly. In fact, this is the same as the knee joint. When qi and blood in a person's body are not smooth, the things absorbed from food can't form blood in time and run the whole body, but become redundant fat, which accumulates in a certain part of the body, forming fat and increasing people's weight. My little colleague, when practicing kneeling posture, lost the fat on his thigh, precisely because fresh blood washed away the accumulated fat. Kneeling can open the nose point of the calf, so that qi and blood will drop, blood stasis will dissipate and the pain will disappear naturally. Traditional Chinese medicine believes that the knee is the house of tendons, that is to say, the knee is the place where tendons are hidden and the meeting of tendons. However, Huangdi Neijing also said that "the liver governs and tonifies" and "the liver opens the eyes", so the kneeling method also has the effect of nourishing and protecting the liver. Many people insist on kneeling for a period of time and inadvertently find that their eyesight has improved, which is also an unexpected gain!
