Brief introduction to the characteristics of Tomb-Sweeping Day gas

Tomb-Sweeping Day gas is characterized by high temperature, clear weather and budding vegetation.

Qingming is a solar term representing phenology, which means sunny weather and lush vegetation. As the saying goes, "Qingming breaks snow, Grain Rain breaks frost." When the weather is clear, the climate in South China is warm and the spring is strong. However, before and after Tomb-Sweeping Day, cold air still invaded from time to time, even making the daily average temperature lower than 12℃ for more than three consecutive days. In the northwest plateau, due to the cold winter, insufficient forage and weak resistance of livestock, it is necessary to guard against the harm of strong cooling weather to old, weak and young livestock after spring.

"There are many rains during the Qingming Festival" is a portrayal of the spring rain in the south of the Yangtze River by Du Mu, a famous poet in the Tang Dynasty. But in some areas, this is not the case. In particular, the western part of South China is often in the spring drought period, and the rainfall in early April is generally only 10 to 20 mm, which is less than half that in the south of the Yangtze River, although there are more spring rains in the eastern part of South China.

1. Sacrifice to sweep the grave: Tomb-Sweeping Day is a solemn festival to sweep the grave and worship the ancestors. This day is a festival to sweep the graves, remember our ancestors, express our thoughts and gratitude to our ancestors, and promote filial piety.

2. Go for an outing: During the Qingming Festival, the sun is shining and the vegetation is lush. It's a good time for an outing, and it's also a spring outing. Because ancestor worship is often in the suburbs, ancestor worship and outing are combined to remember ancestors and be healthy.

3. Insert willow: On this day in Tomb-Sweeping Day, many people will insert willow at the door and under the eaves, commonly known as driving away epidemic ghosts. People think wicker has the function of exorcising ghosts and evil spirits. Some people say it is to commemorate Shennong, the ancestor of farming, who taught the people to cultivate crops.
