Find a copy of the "Dictionary of Appreciation of Tang Poetry" published by Shanghai Dictionary Publishing House, and read the relevant content on pages 496-497, so that everything will be clear to you. I think this is the poet's own poem. During the poet's journey of wandering and struggling for a living, perhaps because he had met such a "beautiful woman" with a tragic fate and noble sentiments, the poet happened to "sympathize with her", just like Bai Juyi later met the Pipa Girl, "we are both at the end of the world" "Reduced human being", so he used the misfortune of a beautiful woman to write about his own tragic fate.
The poet had gone through untold hardships and risked his life, traveling from Henan to Shaanxi, and was loyal to the Tang Dynasty. He only became a Huazhou Sigong and joined the army and was forced to resign. In the situation where the road is as tough as iron and there is no food and clothing, he still can't forget the peril of the country and the nation. Such unfair suffering and such high moral integrity are no different from the "beautiful woman" described by the poet. When a poet writes about "beautiful woman", he writes about himself. "Beauty" is a woman who was abandoned in troubled times, while the poet is a talented and loyal man who was abandoned by the rulers of the time.
