Deep in the valley, where the air became cold, a fishing boat sank by the waterfall.

The meaning of this poem is: The water level drops, Zhou Yuliang emerges, and the cold weather makes Yunmengze deeper.

This poem is from "Climbing the Swallow with Friends" by Meng Haoran, a poet in the Tang Dynasty. It not only depicts Zhou Yuliang's shallow dryness and Yun Mengze's profundity, but also implies the author's state of mind and expresses the author's feelings about the life situation.

Among them, "shallow" refers to water, and because of "falling into the water", Zhou Yuliang is more exposed to water. "Deep" refers to a dream, which is endless and profound.
