The characteristics of Du Fu's lyrical scenery writing by climbing the mountain.

The first four sentences are lyrical by borrowing scenery: the poet looks up at the rustling leaves and overlooks the rolling river. While writing about the scenery, he expressed his feelings affectionately. "Endless" and "inexhaustible" make "rustling" and "rolling" more vivid, which not only reminds people of the sound of falling trees and the surging Yangtze River.

The last four sentences are lyrical: "coming to power alone" shows that the poet is overlooking from a height and closely connects his eyes with his heart. Frequent visitor points out the poet's wandering life. "One hundred years" means a limited life, here refers to the twilight. The word "sad autumn" is not necessarily sad, but the poet witnessed the desolation and magnificence of autumn scenery. Thus, infinite sadness arises spontaneously. The poet summed up the feelings of a long-time guest who is most likely to be sad and sick and loves to go on stage alone into a pair of "bold, broad, muddy and loud" couplets, which made people deeply feel his heavy emotional pulse. The "Wan Li", "Centennial" and "Endless" of the previous couplets also have a mutual echo function: the poet's mental journey. Love and scenery blend together. The poem gives the general meaning of homesickness, adds the content of long-lost loneliness, adds the feeling of sadness in autumn, and adds the sigh of people who left their hometown in Wan Li in their twilight years, making the poem more profound.
