What do you mean, "Good rain tells the season when spring comes"?

Good rain knows the solar terms of rain, just when plants germinate and grow.

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.

This is a masterpiece depicting the rainy scene on a spring night and showing a happy mood. Praise "rain" with a "good" word from the beginning. In life, "good" is often used to praise people who do good things. Praising rain with "good" now will arouse the association of people who do good things. Next, personify the rain, saying that it "knows the season" and knows how to meet the objective needs. Among them, the word "knowledge" is used incisively and vividly, which simply brings the rain to life. Spring is the season when everything germinates and grows. As long as it rains, it begins to rain. It's really good.
