What do you mean, spring rains shake the spring and clear the valley?

This is a sentence in a ballad, which is convenient for me to remember in the 24 solar terms. It refers to the spring (vernal equinox) rainy (Grain Rain) frightened (frightened) spring (beginning of spring) sunny (mysterious) valley (Grain Rain) day.

The full version is: Spring rains shake the spring and clear the valley, and summer is full of mountains and summers. Autumn dew, autumn frost, little snow in winter and cold in winter. The two festivals remain unchanged every month, with a maximum difference of one or two days. The first half of the year is June 2 1 day, and the second half is August 23.
