Autumn pool night rain rose spoofs the next sentence.

Seeing this sentence, I remembered two poems in Late Rain by Li Shangyin, a poet in the Tang Dynasty: "You came back late, and it rained late in the autumn pool." But this is obviously not the answer, because it is not only copying the original sentence, but also not original, which is not funny at all. After thinking about it over and over again, I went on to the next funny sentence: you ask that the return date is not fixed, unless you swim back with another turtle. The flood prevented me from going home. "Turtle" means humor, so it is a joke. )
