The unity of man and nature means that man should conform to the laws of nature.

For example, work at sunrise and rest at sunset. Early to bed and early to rise, not staying up late.

Increase or decrease clothes with the weather.

One side of the soil and water support the other side, and the food should be mainly local seasonal and natural grains, fruits and vegetables.

Exercise, people have to exercise when they are alive. Exercise regularly and love work. Can't covet comfort, too lazy to move.

And ... . . . . Wait a minute.

If people violate these natural laws for a long time, they will have physical problems, get sick and be punished by nature.
