In winter and March, this is called hiding, complaining about water and ice, not disturbing the sun, lying early and getting up late, waiting for the sun, if the ambition is hidden, if it is private, it will be warm and cold, and it will not release the skin, making it urgent. This winter air should be the way to keep Tibet. On the contrary, it hurts the kidney, spring is fatigue, and there are few people alive.

The three months of winter, the so-called hiding, is the season when vitality lurks and everything hides. On this festival, Shui Han is frozen and the earth is cracked. People should go to bed early and get up late, and get up as soon as the sun shines. Don't disturb the spirit of the sun easily.
