The poem "Qingming" is written by Du Mu, a writer in the Tang Dynasty. The poem is about what you see in the spring rain at Qingming, with light colors and a bleak state of mind, and has been widely recited throughout the ages. The first line explains the scene, environment and atmosphere; the second line writes about the characters and shows their bleak and confused state of mind; the third line suggests how to get rid of this state of mind; and the fourth line writes about the answer with action, which is the highlight of the whole piece.
