The whole poem of Delighting in Rain on a Spring Night 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.

Translated as:

Good rain seems to pick the right time, arrival in the spring when everything is born.

With the breeze, quietly into the night. Fine and dense, nourishing everything on the earth.

Thick dark clouds covered fields and alleys, and small lights were lit, and fishing boats on the river flashed.

Look at the flowers with dew tomorrow morning, and Chengdu will be full of flowers.
