The origin of Tomb-Sweeping Day: It is said that during the Spring and Autumn Period, Zhong Er, the son of the Jin Dynasty, was forced into exile. During the exile, one day there was no food, and Zhong Er, the son of the Jin Dynasty, fainted on the ground. Jie Zhitui cut off a piece of meat from himself and cooked a pot of broth for Zhong Er. Zhong Er recovered gradually after eating it.

Later, Zhong Er became Jin Wengong, and the ministers were promoted, only to forget the introduction of Jie, and Jie pushed back. Jin Wengong took someone to ask Jiezhi to push him out of the mountain, but he couldn't find it after climbing the mountain. Helpless release Yamakaji, he accidentally burned Jiezhi. In order to commemorate Jietui, Jin Wengong designated this day as Tomb-Sweeping Day.

Tomb-Sweeping Day has the custom of sweeping graves and hiking. Spring outing, also known as "spring outing", usually refers to going to the suburbs in early spring. This kind of suburban activity has a long history in the Chinese nation. Tree planting has gradually become a routine project, which is actually an official affirmation of the long-standing tree planting custom. Influenced by the Han culture, the other 24 ethnic minorities in China also have the customs of Tomb-Sweeping Day.
