What kind of scene does Du Fu's climbing couplets depict?

"Leaves fall like the spray of a waterfall, while I watch the long river roll forward." Since Du Fu ascended the mountain in the Tang Dynasty.

This couplet embodies the typical characteristics of Kuizhou in autumn.

The poet looked up at the endless rustling leaves and looked down at the endless rolling river. While writing about the scenery, he expressed his feelings affectionately.

Endless and inexhaustible, it makes the rustling roll more vivid, which reminds people of the rustling of fallen trees and the surging Yangtze River, and invisibly conveys the feeling that youth is fleeting and ambition is hard to pay.

Through the gloomy and sad dialogue, it shows superb brushwork, and it does have the majestic momentum of "repairing the palace" and "pouring hundreds of rivers into the east". It is reasonable for predecessors to call it "the absolute step of the past and the present" and "the transformation in the sentence"
