Good rain knows the season, when spring comes.

Sneak into the night with the wind, moisten things silently.

The night is dark and the river is bright.

Look at the red and wet place, the flowers in Jinguancheng are heavy.

The final couplets are not places of interest, but the author's imagination. Imagine, after a night of spring rain, Jinguan City at dawn must be full of flowers, colorful and full of vitality.

Red wet means that the flowers in spring are wet by rain, and the clock means that the flowers look wet by rain, but they are more delicate. I believe you must have noticed that the flowers wet by drizzle in spring look more crystal clear and full of vitality, as if they had been moistened and cleaned. It is precisely because the spring rain brings vitality that Du Fu should praise it!

Jinguan city Chengdu used to be called.
