Conclusion: On the poet's "worry" from the perspective of "Looking at the West of Xianyang and Building the West" (Xu Hun) combined with the content of the poem.

Wan Li's sorrow began with homesickness, and the Willow River Bridge in Qiushui is related to the sorrow of others. The word "sorrow" was used in the first sentence, which laid the tone of the whole poem.

It is said that the poet is looking at the fence. It is likely that the red sun has gradually faded to Bo Xishan that day. I don't know how long it took, but suddenly I saw clouds rolling and clouds relaxing, and the dusk was boundless. In a short time, it was approaching the temple pavilion in the west. When the cloud's birthday falls, the realm changes in an instant, but then a cool breeze blows to the city, suddenly blowing the towers more and more empty and bare. The poet knows from his "life experience" that the wind is a harbinger of rain, and the wind is quiet and the rain is imminent. The scenery has moved and the mood has changed. "The clouds began to sink in the pavilion."

At sunset in Yun Qi, it was stormy. On the basis of the "fact lesson", it is promoted layer by layer, orderly, and naturally shows people the "forced situation", so that people in it must make their own choices: wait and see, head-on or retreat? It is such an artistic conception that people later borrowed the urgency of political struggle or the omen on the eve of emergencies.
