Traditional Chinese medicine health care emphasizes the unity of man and nature, and health care should be adjusted appropriately with the climate changes of four seasons, cold and hot summer, so as to achieve the harmony between man and nature and the balance of human body itself. Traditional Chinese medicine health care also pays equal attention to both body and mind, which not only pays attention to the exercise and maintenance of the tangible body, but also pays attention to the cultivation and recuperation of the mind. The body will affect the mind, and the mind will also affect the body. They are two sides of a whole, and they are indispensable. At the beginning of the formation of western philosophy, the theory of world five elements similar to that of yin-yang and five elements of traditional Chinese medicine was put forward. It is believed that the world is composed of "water, fire, earth and wood", and the fifth element "ether" is something that can transform the other four elements into each other. At that time, the theory of five elements in the West was not only applied to philosophy and religion, but also to medicine, forming a very huge system, which was very similar to China's Yin-Yang and Five Elements. Modern health preservation, like modern medicine, is based on reductionism, that is, turning complex human organs into tissues, and then turning tissues into biomolecules to study. Modern health preservation mainly focuses on the analysis of nutrients, vitamins and other substances that bring benefits to the human body. Nutrition refers to the biological process that the human body ingests, digests, absorbs and utilizes the nutrients in food to meet the physiological needs of the human body. Vitamins are essential nutrients to maintain human health. They can't be synthesized in the body, or the amount of synthesis is difficult to meet the needs of the body, and they must be supplied by food.

Both the East and the West are looking for ways to stay healthy in nature. Both hope to make people live healthier, longer and happier in some way.
