Traditional Chinese medicine health preservation is mainly to nourish the heart. Those who get God will live, and those who lose God will forget. Therefore, to pay attention to the essence of restraint is to recharge your batteries and nourish your spirit. Achieve "righteous memory, evil can't be done." Pay special attention to the cultivation of kidney qi, because Chinese medicine believes that kidney qi is the "innate foundation" of human beings. By adjusting body, qi and mind, we can enter a spiritual realm of harmony between man and nature and selflessness. It can dredge the whole body's meridians, especially the Ren meridian and Du meridian, make the whole body's qi and blood run smoothly, stimulate the qi between the kidneys to run, and nourish the brain along the Du meridian. Because the brain is a sea where kidney essence gathers.
