Four seasons change, winter goes and spring comes, which reflects the relationship between yin and yang.

The four seasons change, and winter goes to spring, which reflects the growth and decline of yin and yang.

The restriction of yin and yang, that is, the mutual inhibition and restraint of yin and yang, is mainly reflected in the mutual growth and decline of yin and yang.

If spring should be in summer, it is warm because the rising of yang in spring and summer inhibits the cold air in autumn and winter; The reason why it is cold in autumn and winter is that the rise of Yin Qi in autumn and winter inhibits the warmth of spring and summer.

Extended data:

The theory of Yin-Yang and Five Elements is China's simple materialism and spontaneous dialectics in ancient times. It holds that the world is the interior of matter, and the material world is nurtured, developed and changed under the impetus of yin and yang.

People think that the five most basic substances, wood, fire, earth, gold and water, are indispensable elements in the world. These five substances depend on each other and are in constant movement and change.

This theory had a far-reaching impact on the later ancient materialist philosophy, such as ancient astronomy, meteorology, chemistry, mathematics, music, medicine, etc., all developed with the help of the theory of Yin-Yang and Five Elements.
