Good rain knows the season. What does it mean when spring is the season?

Meaning of the poem: Good rain knows the solar terms of rain. It is the time when plants germinate and grow, and it falls quietly at night with the spring breeze, silently moistening all things on the earth.

"Good rain knows the season, when spring comes" comes from the first two sentences of Delighting in Rain on a Spring Night written by Du Fu, a poet in the Tang Dynasty. The whole poem is as follows:

Good rain knows the season, when spring comes.

Sneak into the night with the wind, moisten things silently.

The wild path is dark, and the river is bright.

Look at the red and wet place, the flowers in Jinguancheng are heavy.

What a good spring rain! It seems to know the change of seasons. When spring comes, it will come naturally. With the gentle breeze floating quietly at night, it moistens everything gently and silently. The sky over the wild path was overcast and dark, and only the boat on the river was still lit with a solitary lamp. In the morning, watch the spring flowers everywhere in the drizzle, which are blooming in beautiful Chengdu.
