The Chinese nation has had the custom of going for an outing in Qingming since ancient times. In ancient times, it was called spring outing, spring seeking and so on. Spring outing, also known as spring outing, refers to going for a walk in the suburbs in early spring. Before and after Tomb-Sweeping Day, the spring was bright and the spring rain was falling, and the survival rate of planted seedlings was high and the growth was fast. So there is a habit of planting trees in Tomb-Sweeping Day, and some people call Tomb-Sweeping Day Arbor Day. Flying kites is the most popular activity in Tomb-Sweeping Day. Kite is an aircraft that sticks paper or silk with bamboo strips and other skeletons, pulls a long line on it, and drops it into the sky under the action of wind. It belongs to an aircraft that only uses aerodynamic force.
Tomb-Sweeping Day's grave-sweeping, which means "grave-sweeping sacrifice", is a "respect for time and thought" for ancestors. Sacrificing ancestors is a way of remembering ancestors, and its custom has a long history. Tomb-Sweeping Day and China have the folk custom of inserting willows. There are three theories about the origin of the custom of inserting willows in Tomb-Sweeping Day. Some experts believe that the custom of inserting willows is to commemorate Shennong, the agricultural ancestor who taught people to grow crops. In some places, eating eggs in Tomb-Sweeping Day is as important as eating zongzi on the Dragon Boat Festival and eating moon cakes on the Mid-Autumn Festival. According to folk custom, Tomb-Sweeping Day has good health all year round after eating an egg.
