2. The characteristics of rain solar terms

It began to rain, and it gradually increased. The rainy season means that it begins to rain and the rainfall gradually increases. In the Yellow River Basin, the birthplace of the twenty-four solar terms, the weather was cold before it rained, but there were snowflakes flying and the rain was falling, which was unpleasant. After the rain, the temperature can generally rise above 0℃, with less snow and more rain. However, in the warm southern region, even in the dead of winter, rainfall is not uncommon. The average temperature in most parts of southern China in this period is above 10℃, peaches and plums are in bud, and cherries are in full bloom. It has indeed entered a climatic spring. In addition to a few years, the frost period has come to an end. It is timely to graft fruit trees and plant trees. After a dry winter in South China, there are many droughts in spring all the year round, especially in the west of South China. Spring rain is as expensive as oil. In addition, the invasion of cold wave will cause strong cooling and snowstorm, which will do great harm to the old, weak and young animals.
