What season is it to sneak into the night with the wind and moisten things quietly?

It is spring to sneak into the night with the wind and moisten things silently. Sneaking into the night with the wind, moistening things silently comes from Du Fu's Delighting in Rain on a Spring Night, which is a poem about spring.

Sneak into the night with the wind, moisten things silently, that is, fall quietly at night with the spring breeze, moisten things silently in spring. This poem describes the characteristics of Chengdu spring rain and the scene of rainy night with personification, and enthusiastically eulogizes the timely moistening of spring rain.

A Brief Introduction to the Creation Background of Delighting in Rain on a Spring Night.

Delighting in Rain on a Spring Night was written in the spring of the second year of Shang Dynasty (AD 76 1). When writing this poem, Du Fu had lived in Chengdu Caotang for two years. After a period of exile, Du Fu finally settled in Chengdu. He cultivates self-cultivation, grows vegetables and flowers, and interacts with farmers. He has deep feelings for the spring rain, so he wrote this beautiful poem, describing the rain on a spring night and nourishing everything.
