"Sneak into the night with the wind and moisten things silently." This is a poem praising the teacher. These two poems are often used to praise the teacher's education of students, just like the spring rain moistening things.

In fact, this is Du Fu's longing for a quiet life. In the spring of the first year of Su Zong Shang Yuan (760), Du Fu came to Chengdu, far away from the war-torn land of Guanzhong. He finally lived a stable life in Shu. He lived in a thatched cottage in the country, ending his wandering days. He cultivates fields, vegetables and flowers by himself, and has a different feeling about the spring rain.

When he heard the rain in spring, his heart was filled with infinite joy. This joy is a rare emotion during the war, so he wrote:

Delighting in Rain on a Spring Night

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.
