What are the allusions to the ascent of Qishan No.9? What feelings did the poet express?

Allusion: The poet comforted himself with the cries of Qi Jinggong and Niu Shan. When the poet saw Qishan in Chizhou, he remembered Niu Shan's tears in Qi Jinggong.

Lyric: The poet thinks that life is impermanent, and he feels "stepping on the ground and hating the light", which has always been the case. Since there is no such hatred in this world, there is no need to cry alone like Qi Jinggong. Taking Qi Jinggong's counterexample as the conclusion, it shows that this broadness contains a kind of bitterness.

Climbing Mountain No.9 _ Baidu Chinese

Author: Du Mu

On the river, the geese just flew south, and they made friends with wine and hip flask mountain.

Laughter makes people laugh, when chrysanthemums are in full bloom.

Only by indulging in the Double Ninth Festival, there is no need to sigh and hate the afterglow of the sunset.

After all, life is a short history, so why do you cry like Qi Jinggong?
