Yang Guifei didn't die in Mayi post, but lived among the people. This statement reflects people's sympathy and nostalgia for her. Yu Pingbo, a famous redologist, made textual research on Bai Juyi's Song of Eternal Sorrow and Chen Hong's Biography of Song of Eternal Sorrow in On Poetry. He thinks that Yang Guifei didn't die in Ma Yitie, otherwise it would be enough to write it to Ma Yitie on the topic of "Long Hate", and there is no need to write about Lin Qiong Taoist and Jade Princess. At that time, the army mutinied, the imperial concubine was robbed, and Tang Xuanzong was helpless and "hopeless." The imperial edict of granting death contained in the official history did not exist at that time. Yu Pingbo also pointed out that Yang Guifei lived in the "Imperial Palace of Jade Princess", that is, a Taoist temple for women. The so-called "Haixian Mountain" actually refers to the Taoist temple of female Taoist priests. The concept of female Taoism in the Tang Dynasty is essentially the same as that of a brothel. Later, Xuanzong found her and found that she had become a flower and a willow, so he didn't take her back to the palace. As for Chen Hong's "Song of Eternal Sorrow", "Make people take it" means that the imperial concubine has been taken far away.
