When did Delighting in Rain on a Spring Night describe it?

"Delighting in Rain on a Spring Night" Tang Du Fu

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.

Venue: Caotang near Huanhuaxi, Chengdu

Time: Du Fu wrote this poem in 76 1 year (the second year of Tang Suzong Shangyuan), on a spring night.

"Happiness" represents the timely rain, the beauty of the rainy night, and the charming scene of Jinguan City in the early morning after the rain.
