Motherland medicine is nothing more than six words for health preservation, and its formula for health preservation is: "broadmindedness, nutrition and exercise." "Broad-minded" means having a good mood every day and always being optimistic. "Nutrition" means coarse grains and light meals, chewing slowly, and eating only seven points full for three meals. "Sports" is an opportunity to strive for all sports. Everyone should earnestly establish this concept of health and take health actions immediately, and health will reward you: individuals will not suffer, family members will not suffer, medical expenses will be saved, and the whole society will benefit.
