Grain of grain in 24 solar terms

There are three times for the grain of grain: the first is for Mantis to be born; the second is for the beginning of the sound; the third is for the tongue to be silent. This means that in this solar term, the eggs laid by mantis in the late autumn of last year broke their shells and gave birth to small Mantis; the shady shrike began to appear in the branches and sing because of the shade; on the contrary, the anti tongue birds, which can learn from the singing of other birds, stopped singing because they sensed the appearance of Yin Qi.
