Sneaking into the night with the wind, moistening things quietly and describing what kind of weather it is

These two lines of poems come from Du Fu's "Spring Night Happy Rain" and describe the weather as light rain.

Good rain knows the season, and spring will happen. Sneaking into the night with the wind, moistening things silently.

The wild paths are all dark with clouds, but the river boats are only bright with fire. Look at the red and wet place at dawn, the flowers are heavy on the official city.

It can be seen from the whole poem that the author mainly describes the scene of light rain on a spring night.
