In the history of China, eating cold food and forbidding fire to pay homage to ancestors has long been a custom. After the Tang Dynasty, the Cold Food Festival gradually declined, so it became a continuous festival tradition for Tomb-Sweeping Day to sweep graves to worship ancestors.

Go for an outing and Tomb-Sweeping Day, it is spring back to the earth. People took advantage of the opportunity of sweeping graves, and the whole family, old and young, enjoyed themselves in Shan Ye. After returning home, they conveniently folded some budding willow branches and put them on their heads, having a good time.

Tomb-Sweeping Day, it is the time when willows sprout and smoke green. There are folk customs of folding willow, piercing willow and inserting willow. When people go out for an outing, they break off some wicker branches, which can be played with in their hands, woven into hats and worn on their heads, or taken home and inserted on the lintels and eaves.

Flying kites is one of people's favorite activities in Tomb-Sweeping Day. The ancients believed that if someone was sick, they could write down or draw their illness on the kite, tie the kite in the air with a string, let it fly to the sky, cut the cable, and the disease disaster would fly away with the kite. Later, kites gradually developed into a popular outing entertainment.
