The historical origin of Grain Rain;

1, Grain Rain, is the last solar term in spring, and Grain Rain is taken from the meaning of "Rain gives birth to hundreds of valleys". In the traditional farming culture, the solar terms in Grain Rain link "valley" with "rain", indicating the precipitation situation, and "rain gives birth to hundreds of valleys".

The most important feature of Grain Rain is the continuous spring rain, which embodies the significance of "Grain Rain" in agricultural climate and is also the reflection of ancient farming culture on festivals. After the solar term in Grain Rain, the temperature rises, the rainfall increases, and the humidity in the air further increases, which is very suitable for the growth of cereal crops.

" "Qunfangpu" also records: "Grain Rain, there is rain in the valley." Before and after Grain Rain, the weather turned warmer and the rainfall increased, which was beneficial to the sowing and growth of spring crops.

It is recorded in the twenty-four solar terms: "In mid-March, after the rain, the ground 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 valley and sow, from top to bottom. " At this time, the weather is mild and the rainfall increases obviously, which has a great relationship with the growth and development of cereal crops.
