At this time, the crops in the field need rain to moisten them. There is a saying that "Spring rain is as expensive as oil". In ancient China, agriculture depended on the weather.

As for the origin of Grain Rain, according to Huai Nan Zi, the creation of characters in Cang Xie is an earth-shattering event. The Yellow Emperor issued imperial edicts in late spring and early summer, announcing the success of Cangjie's word-making, and calling on all the people in the world to * * * the ambition of Xi. On this day, there was an unusual rain, and countless Gu Mi fell as comfort. Later generations named this day's Grain Rain as one of the 24 solar terms, which is now the "Grain Rain" solar term.
