Which of the following poems describes the spring rain?

Good rain knows the season, when spring comes. Sneak into the night with the wind, moisten things silently. -Du Fu's "Delighting in Rain on a Spring Night"

There is a lot of silk in the sky above the avenue, which is as delicate and moist as butter. The grass is vaguely connected in the distance, but it looks sparse in the near future. -Han Yu

Mourning day, drizzle like tears; Pedestrians on the road want to die. -Du Mu

The spring breeze is vast and the spring rain is continuous. Flowers condense, willows bring cold smoke.

Spring rain is as expensive as oil and flows all over the street.
