"Twenty-four solar terms" is the product of ancient farming civilization. It is a knowledge system formed by ancient ancestors following the farming season and observing the movement of celestial bodies to understand the changing laws of seasons, climate and phenology in a year. The twenty-four solar terms were originally formulated according to the changes of stars. The Big Dipper rotates in a circle and bucket handle rotates clockwise, which is called one of the "years".
Qingming, one of the 24 solar terms, is the fifth solar term in spring. When the sun reaches longitude 15, the sky is clear. During the Qingming period, the atmosphere was clear and everything appeared, hence the name. Qingming is both a solar term and a festival. Tomb-Sweeping Day is a good time for spring ploughing and planting; Tomb-Sweeping Day is a traditional festival for people to express their feelings and comfort themselves. Tomb-Sweeping Day Qi provides important conditions for the formation of Tomb-Sweeping Day customs in terms of time and weather phenology.
In Tomb-Sweeping Day, the weather in most parts of China is no longer cold, and it has entered the spring. The weather here seems to be two different days in the north and south. The north is dry and rainy, and the south is wet and rainy. Tomb-Sweeping Day is first of all a very important solar term. As soon as Tomb-Sweeping Day arrives, the temperature rises, which is a good season for spring ploughing and planting. Therefore, there is a saying that "melons and beans are planted before and after Qingming". Agricultural proverb "Planting trees is not as clear as Qingming".
