What does this poem mean, sneaking into the night with the wind? Where did it come from?

1, the interpretation of this poem is: Good rain knows the solar terms of rain. It is when plants germinate and grow that it quietly falls at night with the spring breeze, silently moistening everything on the earth. On a rainy night, the fields were dark, and only the lights on the river boat were exceptionally bright. After dawn, looking at the flowers with rain, beautiful and fiery red, the whole Jinguan City has become a world of flowers.

2. This poem is from Du Fu's Delighting in Rain on a Spring Night. The whole poem is: 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. Sneak into the night with the wind, moisten things silently.
