China's traditional health care emphasizes the relationship between man and nature, and thinks that man should adapt to the changes of natural environment and climate in four seasons, actively adjust himself, keep a balance with nature and avoid the invasion of external evils. The Book of Changes says that "one yin and one yang is the way"; "The image of law is nothing more than heaven and earth, and it is nothing more than four seasons." (I ching) Laozi said, "Tao is natural." This is the basic requirement of TCM health preservation.
TCM health preservation is a treasure of Chinese traditional culture, and its purpose is to nourish vitality, prevent and treat diseases, and pursue health and longevity. There are many health care technologies in TCM, such as food tonic, medicine tonic, acupuncture, massage, qigong and so on. The ancients thought that the method of keeping in good health was not like replenishing heaven, and the method of replenishing heaven was not like nourishing essence; Fine tonic can transform qi, while strong tonic can concentrate; All spirits are the balance of Yin and Yang, the coordination of zang-fu organs and the smooth flow of qi and blood, thus ensuring the health and strength of the body. Therefore, the maintenance of vigor is the most important content and the foundation of human health. In traditional Chinese medicine, the most important physiological and functional activities of the human body are summarized as essence, qi and spirit, which are considered as the basis of life and the three major elements to maintain the overall life activities of the human body. As early as 2000-3000 years ago, Zhouyi, Huangdi Neijing and Laozi had a complete set of health preservation principles, which were like a treasure house that could never be dug up, and were worth exploring again and again. The concept of TCM health care includes three magic weapons: harmony between man and nature, balance between yin and yang, and harmony between body and mind.
