Use the cry of the ape to express feelings of separation and sorrow. It is not uncommon to write poems about apes crying. For example, Li Bai's poem "The apes on both sides of the strait can't stop crying, and the boat has passed the Ten Thousand Mountains"; Du Fu's poem "The wind is strong and the sky is high, the apes howl, and the white birds fly back from the clear sand of Zhug". "Xuan Shi Zhi" says that apes are "extremely good at howling. People who like to be poets are often said to be good at howling." In fact, just like the above two examples, poets often use the cry of apes to describe the miserable and desolate atmosphere and express their feelings of separation or sadness. For example, Zhang said in "Bie Zijun of Yuezhou" that "Jin Pavilion pulls out the heart grass, and the river road cuts off the ape's intestines"; another example is Li Shangyin's "Ji Ri", "Whenever the goose's foot is encountered, the ape's intestine is cut off where it touches."
