Extended data:

Grave-sweeping is called "respect for time thinking" for ancestors. Its customs have a long history.

The Ming Dynasty's "A Brief Introduction to the Scenery of the Imperial Capital" reads: "In March, in Tomb-Sweeping Day, men sacrificed their ancestors in Qingming Festival, and the road was full of embarrassment. Worshipers, mourners, weeping, weeding, adding soil to graves, burning ingots several times, and buying graves with paper money. If you can't see the paper money, it will be a lonely grave. After crying, don't go back, go to the fragrant tree, choose the garden, and sit down and get drunk. "

In fact, grave-sweeping began before Qin Dynasty, but not necessarily during Tomb-Sweeping Day, but after Qin Dynasty. It was not until the Tang Dynasty that it became popular. In many places in the south, such as Shanghai, Hangzhou, Putian, Dehua, Yongchun, Anxi, Chaoshan, Hainan, Kunming and other places, the customs in other parts of Fujian are different, and the time of grave sweeping is not uniform.
