Requiring "borrowing scenery to express feelings" is the main technique in poetry creation. Please analyze how Li Bai uses this technique in this poem.

This poem is titled "What am I doing here?" This is the poet's own problem, which is quite a bit of unspeakable indignation and regret. This will attract readers' attention and cause suspense. "High-lying Dune City", with high terrain, actually refers to the poet's idle and boring life. On the one hand, this sentence describes the present life, on the other hand, it also responds to the reasons for raising the above questions. The reason why the poet doesn't "lie high" on the sand dunes is because he misses Du Fu as a friend. The beginning of this row of poems is the complicated and depressed feelings of the poet after his love and happy life disappeared, which is produced in a sudden way.

One or two sentences tend to express subjective feelings, while three or four sentences turn to the description of objective scenery. "There are ancient trees on the edge of the city, listening to autumn sounds every day." For the poet, the sand dune city in front of him seems to have nothing to see except the old trees on the edge of the city, rustling day and night in the autumn wind. "In the middle of the night, the wind and bamboo knock on the autumn rhyme, and Chiba hates it." This bleak autumn wind and sad atmosphere make the poet miss his friends and reminisce about the past, which is even more difficult for him to care about. "There is a yearning for parting, Yao Se and Jin Zun." However, here and now, this situation is extraordinary, wine can't eliminate sorrow, and songs can't forget sorrow. Lu and Qi refer to Shandong where the poet was at that time. "Don't get drunk" means that you are not interested in getting drunk. "Empty feelings", because the poet has no intention to appreciate, and can only sing sentimentality. Such rewriting will greatly increase the weight of lyricism, and at the same time, it will also force the following.

Wenshui, which originated in Laiwu, Shandong, flows to the southwest. Du Fu bid farewell to Li Bai in Lu County and wanted to go to Chang 'an, which is also located in the southwest of Lu. Therefore, the poet said, "My yearning for you is like this mighty river, which follows you south day and night." The poet sends his feelings to the flowing water, takes care of the title of the poem and points out the main idea. The artistic conception of flowing water and endless lovesickness make the language enjoy a long charm. This kind of endless thoughts, as well as the kind of "green water on the horizon, green hills on the sea." "Let's meet each other, why get drunk" broad and free-spirited mind. It shows the richness of the poet's feelings and styles.
