It originally refers to a medical activity of Taoism to maintain life, strengthen physique and prevent diseases through various methods, so as to achieve longevity. Raise, that is, the meaning of nursed back to health, maintenance and tonic; Life means living, surviving and growing. In the modern sense, "health preservation" refers to actively maintaining physical and mental health according to the laws of human life process. Maintenance refers to following the law of life, through moderate exercise, plus external care and other means, so that the body function and external skin can rest and restore their due functions, which is the first level of health care.

Nourishing refers to nourishing and conditioning the whole body according to the laws of the four seasons of heaven and earth, so as to achieve the purpose of preventing diseases and prolonging life. The essence of health preservation is to maintain the five internal organs and prolong life. Health preservation is a comprehensive science, involving many disciplines, including Chinese medicine, rehabilitation, nutrition, aesthetics, psychology, Chinese studies, physics, chemistry, art, cooking, kinematics, Buddhism, Taoism, Confucianism and so on. Taoism is a philosophical thought put forward by Laozi and Zhuangzi during the Spring and Autumn Period and the Warring States Period. Their academic thoughts have a certain influence on the formation of TCM health preservation.

Taoism, because it advocates lofty nature and despises narrow utilitarianism, has long been wrongly regarded as extreme by modern people, because modern people mistakenly believe that Taoism has these historical limitations and negative aspects, which has had many adverse effects on China's traditional culture and a certain corrosive effect on the Chinese national spirit. In fact, these views of modern people are extremely wrong. To correctly understand the inaction in Taoist thought, it is not that you don't want to do something, but that everything should be "in harmony with the weather, place and people", rather than acting on subjective wishes and imagination in violation of "in harmony with the weather, place and people".

Laozi's theory of "inaction" is often understood as a negative thought by contemporary philosophers and politicians, but it is actually wrong. Judging from the reflection of the whole philosophical concept in Tao Te Ching, inaction is actually an act without subjective judgment, and no one does it, but it is an act that follows objective laws. Generally speaking, inaction is a scientific behavior, a reasonable behavior, and therefore a positive behavior. In fact, "negative" and "positive" in modern vocabulary are misunderstood by people. Negative is to eliminate paranoia and extremism, which is a very correct behavior.
