Grain Rain, the last solar term in spring. Grain rain is taken from the meaning of "rain breeds hundreds of grains". At this time, the precipitation increases significantly. The seedlings in the field are newly planted and new crops are most in need of rain. The rainfall is sufficient and timely, and the grain crops can grow healthily. Like the solar terms of rain, light full, light snow, heavy snow, etc., grain rain is the solar term reflecting the precipitation phenomenon, and is the reflection of the ancient farming culture on festivals.
During the grain rain season, in southern China, it often begins to rain significantly, and especially in southern China, once cold air meets warm and humid air, it tends to form a long-term rainfall weather. The Qinling Mountains Huaihe River is a transitional area between the spring rain in the south and the spring drought in the north. From the Qinling Mountains Huaihe River to the north, the spring rain decreases sharply. In the northern region, grain rain is the symbol of "the last frost". Due to the increased rainfall after the Grain Rain Solar Term, the humidity in the air gradually increases, and attention should be paid to preventing the invasion of "damp evil". The folk customs in the Guyu solar term include picking Guyu tea, walking in Guyu, eating spring, and appreciating flowers.
