Poor health, i.e. poor physique, has congenital and acquired factors. The congenital factor is predestined, and the acquired conditioning can help to strengthen the body and enhance the body’s resistance to diseases. In the first part of Su Wen, it is mentioned that the important principle of health care is “to follow the laws of yin and yang, to harmonize the arts and figures, to eat and drink in a disciplined manner, to live and work in a disciplined manner, and not to work in a delusional manner”, that is, to live in accordance with the laws of nature, to pay attention to diet and living and not to overwork, and also to pay attention to moderate exercise in order to live a long and healthy life. Chinese medicine also says that emotions cause disease, and mental factors are also a two-way regulation of the body. The ancients believed that those who are good at health care should be anxious to hear and desire less, and that mental tranquility can make the true qi harmonize and not get sick. A happy mood and contentment are also the cornerstones of a healthy mind.
