The second of the 24 solar terms.

The rainy season means that it begins to rain and the rainfall gradually increases. In the Yellow River valley, the birthplace of the 24 solar terms, it was cold before the rain, but it was snowing and raining unpleasantly. After the rain, the temperature can generally rise above 0℃, with less snow and more rain. However, in the warm climate of Sichuan Basin, even in the dead of winter, rainfall is not uncommon. In Sichuan basin, peaches and plums are in bud, cherries are in full bloom, and it is really spring in the climate. 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 the dry winter, there are many droughts in spring all the year round, especially in the west of the basin. In agriculture, attention should be paid to moisture conservation and timely irrigation to meet the water supply at the jointing and booting stage of wheat and the critical period of bolting and flowering of rape. The mountainous area of western Sichuan Plateau is still in the dry season, with low temperature and high wind speed, which is prone to forest fires. 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. These should pay special attention to prevention. Time flies and the seasons remind people. "A year's plan lies in spring". The management of Koharu and the preparations for Da Chun should be carried out quickly, so as to make this year better than previous years.
