As a knowledge of health care and treatment with oriental characteristics, Chinese medicine is also a skill to regulate diseases, prolong life and preserve health for individuals. Chinese medicine pays special attention to mental health, keeping in good health first, nourishing the heart first, and adjusting the shape first. Quiet is an important form, carrier and condition of nourishing the heart and nature. It can be said that the first effort of TCM health preservation is "quietness", which is embodied in the dominant idea of rest. The background of this idea of keeping in good health is Laozi's Taoist philosophy. Taoism attaches great importance to spiritual cultivation and advocates quietness to purify the soul.

Laozi, the founder of Taoism, is good at rest and health preservation. As a centenarian, he advocates the lofty spiritual realm of "being open-minded, quiet and faithful", being quiet and nurturing, abandoning all desires, advocating "going to extremes and being extravagant", and warning people to get rid of those extreme, extravagant and excessive requirements and pursue a calm, quiet and detached state of mind in the process of health preservation. Zhuangzi also believes that human existence is just one of the complicated phenomena in the world, and birth, aging, illness and death are only the necessary procedures in life, just like everything in the world. Therefore, he pointed out in "Zhuangzi Qiushui": "Being born without words, dying without suffering, knowing the end is inevitable." Warn people not to be happy or sad because of the change of life and death, advocate the quietness of health preservation, attach importance to spiritual cultivation, make their hearts want nothing and maintain a good spiritual realm.

Silence is good for keeping god. Sit still and nourish your heart, eliminate distractions, breathe naturally, let your heart not move wildly, let your heart return to your home and your child's state of mind. This can be achieved by guiding deep breathing and calming the heart. At this time, the body is quiet, the muscles are relaxed, the spirit is concentrated, everything is quiet, the qi is running, you can come and go at will, and your body and mind are in a completely comfortable state. This is what Confucianism said in Neijing, such as "be quiet and then be quiet", "cultivate noble spirit" and "hide the spirit inside", Taoism's "introspection" and Buddhism's "staying in the abdomen" and "meditation". It can make qi and blood vigorous, strengthen and eliminate diseases, resist aging and prolong life. Only in this way can we "breathe the essence, maintain spiritual independence and keep the same muscles, so we can cover the world endlessly for a long time." This is the key to why all generations of health-preserving families have kept quiet and kept healthy, lived too long and kept moving.
