What is Delighting in Rain on a Spring Night's poetry?

Poetry: Good rain knows the solar terms of rain. It is when plants germinate and grow, and it falls quietly at night with the spring breeze, silently nourishing everything on the earth. In the rainy night, the field is dark, and only the lights on the river boat are particularly bright. After dawn, look at the flowers with rain, beautiful and red, and the whole Jinguan city has become a world of blooming flowers.

original: good rain knows the season, and when spring happens. Sneak into the night with the wind, moisten things silently. The wild path is dark, and the river boat is bright. Look at the red and wet place, and the flowers are heavy in Jinguan City.
