The theoretical basis of Taoism's concept of health preservation-respecting life, attaching importance to life and combining life with Taoism-is a religion that attaches importance to the existence of secular life. In Taoist view, human life is the most precious. Therefore, the most important task and goal in life is to protect your own life. Taoism cherishes the value of life, which is integrated into Laozi's thoughts of observing life, cultivating life, protecting life, caring for life, being reborn and loving life: observing life is Ming Dow, which is to examine whether people's understanding of life is consistent with Taoism; Cultivating students is training, which is usually called double cultivation of life; Survival is the integration of life and Tao; Protecting life means protecting the existing life connected with Tao; Your life is to cherish the hard-won life; Loving life means loving life and sharing it with Tao. The fundamental principle of Taoist concept of health preservation-in the final analysis, law is natural. Laozi put forward in the 25th chapter of Tao Te Ching: "Man, earth, heaven, heaven and Tao are nature." In other words, heaven, earth, people and even everything must be law, and law is natural. Of course, health care is no exception, and we should also take Tao as the law and nature as the law. Chapter 42 of Tao Te Ching points out: "Tao gives birth to one, two, three and everything." Laozi believes that everything is the result of the continuous development of Tao. In the process of development, everything gradually moved away from the Tao. Therefore, if we want to know Tao and practice Tao, we must follow the direction of Tao's development and do the opposite, so that we can get close to Tao and return to it. This is Laozi's philosophical proposition of returning to basics: everything should be rooted in the roots. In the final analysis, it is static and motionless. Life often speaks, and knowledge often speaks. I often don't know, act rashly, and be fierce. There is no doubt that the result of everything returning to life is to return to the original state of everything, that is, the state of nature. Laozi's concept of health preservation is based on the fundamental principle of "returning to life after roots and relying on nature". He emphasized that the cultivation of human body must follow the way of nature and be integrated with the natural environment. It is embodied in the following five aspects: body and morality, nourishing nature and leading health preservation; Quietism, pure heart and nourishing nature; Zhi Zhi is self-sufficient and lives like nature; Keep a soft place and exercise regularly; Be modest and be kind to your relatives and friends. These principles show that Taoist health preservation is the purpose of Taoist teachings and beliefs based on the way of nature.

Take Tao as the highest belief. Taoism regards Laozi as the ancestor of Taoism, Tao is the origin of the universe, and everything in the universe is born of Tao. Tao Te Ching says: Tao gives birth to one, two, three and everything. Metaphysics also says: "Tao is a system of nothingness, the root of nature, the foundation of God and the element of heaven and earth". Tao, calm and simple, selfless and without desire, dominates everything without relying on itself and letting nature take its course. Tao is the most perfect and noble character. People in the society call a person with high moral character "a man with a way", which is a respect for the way. Taoism takes the Tao Te Ching as its ancestor. Taoist dogma, practice, health preservation, advocating nature, quietism, striving for few desires, frugality and helping others, deep-rooted, immortal, returning to simplicity and so on. All originated from the Tao Te Ching. Therefore, Taoism takes Taoism as its core belief and practices monasticism to improve itself and be kind to others.
