What kind of technique is used in the fourth sentence of "Song of Autumn Pu"?

First, [1] Qiupu looks like autumn, and the depression is worrying. The guests are too worried to go to the East Building. Looking to the west of Chang 'an, you can see the river flowing below. Send a message to Jiang. Do you remember Nong? Send a drop of tears from afar to reach Yangzhou for me.

Secondly, Qiupu apes are worried at night, and Huangshan Mountain is as white as a bald head. Qingxi is not a long stream, but a heartbroken stream. You can't go if you want to. When to return to Japan, rain and tears are lonely.

That song

First, do you use rhetorical questions or rhetorical questions? The first song expresses the poet You Qiupu's melancholy mood and nostalgia for Chang 'an when he wants to arrive in Yangzhou. The whole poem can be divided into two paragraphs. The poet who wrote the first six sentences was sad when he saw Qiupu, and climbed the mountain because of his sadness. Looking at Chang 'an from the top of the building adds another layer of sorrow, such as the water of the Yangtze River flowing eastward. The last six sentences are anthropomorphic, expressing that the Yangtze River water has the meaning of going to Yangzhou.

The second is exaggerated. The second poem is about the poet's long journey. "Sorrow" is the center of this poem. The first four sentences are written because I am worried about myself, so I feel worried about apes, mountains and water. The last four sentences are about the cause of worry: I don't return to Japan after a long trip, sitting alone in a boat, and crying like rain.
