Traditional Chinese medicine (TCM) is the way of keeping in good health for the Chinese nation, which basically summarizes the health-keeping theories of medicine, diet, religion, folk customs, martial arts and other cultural aspects for thousands of years. Its content is nothing more than the following four points: 1. Let nature take its course: it embodies the idea of "harmony between man and nature". It is emphasized that in the process of health preservation, we should conform to the laws of nature and not violate them. At the same time, we should also attach importance to the unity and coordination between man and society, and man should be unified with the natural environment and society. As Huangdi Neijing said: "Knowing astronomy from above, geography from below, and personnel from the middle can last long." 2. Double cultivation of body and mind: In the process of health preservation, we should not only pay attention to physical maintenance, but also pay attention to mental and psychological adjustment. The so-called "having both form and spirit", "keeping the whole form" and "keeping the form concentrated on the whole". 3. Combination of motion and stillness: Modern medicine advocates "life lies in exercise", and Chinese medicine also advocates "exercise generates yang" and advocates exercise and fitness. However, Chinese medicine also advocates "moving is quiet" and "not acting rashly". As the Zhouyi Biography said, "Motion and static contain each other, thinking that everything changes", "Jing? 6? 1 Yi Yi said: "Everything in the world is based on motion and static. "4. Comprehensive and thoughtful care: health care is not limited to one method or type, and health care activities should be carried out in many aspects, including body, mind, movement, tranquility, food and medicine. In addition, different health preserving methods should be adopted according to different people, different places and different times, so-called "nursing based on cause" and "nursing based on syndrome differentiation".
