The fresh weather is like a serious illness. What do you mean?

A: Fresh weather is like recovering from a serious illness, which means that the previous weather was foggy and dusty, just like the human spirit. Fog and dust are as dim as a person's face. Now the weather is fresh, clear and sunny, which means that when the weather is cured, it will be like a person's illness, and the qi and blood will be reconciled, and the face will look good.
