In terms of health preservation, the representative academic thoughts and viewpoints of Confucianism can be found in many Confucian classics. For example, in terms of psychological adjustment, The Book of Rites says: "The heart is complete with you, but it hurts with you." Nourishing the heart and shape is an important part of health preservation. However, between spirit and body, it is spirit that plays a leading role.

First of all, health care should emphasize spiritual adjustment, and the best way is to reduce material desires, which is the so-called "nourishing the heart is not good at lust." It is normal to have desires in life, but they can only be realized under the conditions of social permission, and there can be no excessive demands, which requires following the principle of "courtesy".

Paying attention to physical health care is also an aspect of Confucian health care thought. Arrange life reasonably, pay attention to daily life, combine work and rest, and eat moderately. Is the basic principle of medical care. On the other hand, if we don't pay attention to these principles, "people have three deaths, not their lives, and they have taken them." If the husband is uncomfortable in the bedroom, has a poor diet and is overworked, he will be killed by the disease. "These are the causes of physical injury and poor medical care, and we need to pay attention to them.

In addition, Confucius also pointed out: "There is no sense of security in life." This means that the living environment and conditions cannot be too comfortable, otherwise, people will easily become lazy, depressed, decadent, weak and unhealthy. He adjusted his residence and clothes according to the climate changes of the four seasons to adapt to the changes of the external environment.
