I Preservation of Health
In accordance with the principle of correspondence between human beings and the natural environment, traditional Chinese medicine holds the view that people, living in an environment constituted by Nature, must accord well with the seasonal changes in it, accommodating themselves in good time to such changes so as to keep the yin and yang of their bodies in equilibrium and to ensure at the same time the harmonious coexistence of their individual organisms with the external world so as to reach the aim of preserving themselves in good health, lengthening their lifespans and attaining longevity.
