Characteristics of Grain Rain's Origin Story in the Twenty-four Solar Terms

We can see its origin in related classics. For example, in Tongwei's Filial Piety to Help the Gods, it is said: In the fifteenth day after the Qingming Festival, the bucket refers to Chen, which is Grain Rain. In mid-March, it is said that the rain gives birth to hundreds of valleys, which are clean and bright. It explains the date. And "Qunfangpu" records: Grain Rain, the valley was born because of rain. It means that around Grain Rain, the weather gets warmer and the rainfall increases, which is beneficial to the sowing and growth of spring crops. In addition, the "Twenty-four solar terms" has a more detailed description: in mid-March, after the rain, the soil paste pulsates, and now it rains, and its valley is in the water. Rain is silent, just like the rain in my field. At this time, cover the grain and sow, from top to bottom. It can be seen that this solar term has a great relationship with the growth and development of cereal crops.
