One view is that Yang Yuhuan may have died in a Buddhist temple. It is recorded that after Chen and others killed Yang and his son, they strongly demanded to be executed on the grounds that "the future trouble has not been removed". Tang Xuanzong had no choice but to bid farewell to the imperial concubine and give orders. Yang Guifei hanged herself in the Buddhist temple.
Some people think that Yang Guifei may have died in troubled times, which can be seen from some descriptions in Tang poetry. Du Mu's Poems such as Biography of Yang Guifei in the Old Tang Dynasty, Calling Ma Su's Blood and Pulling the Feather Gun, and Wen's Blood Buried Princess all think that Yang Guifei was killed by the Ma Luanjun. Some people say that there are other possibilities for Yang Guifei's death, while others say that she actually died by swallowing gold. This statement only appears in Liu Yuxi's poem "Returning to the Soul without Inspection, Burying Blood and Growing Grass". There is also a saying that Yang Guifei did not die in Mavai, but was exiled to Shu Ren and sent to the people. Maweixing and Yu Pingbo's textual research on Bai Juyi's poems and songs, and Chen Hong's Song of Eternal Sorrow.
He thinks that Bai Juyi's Biography of Eternal Sorrow and Chen Hong's Eternal Sorrow have other meanings.
There is also a saying that Yang Guifei finally fled to Japan. In the fifth issue of Song of Eternal Sorrow published on 1984, Zhang Lian translated a series of Japanese cultural translations, saying that Ma Youyi was a hanged maid at that time. General Chen was attracted by the beauty of the imperial concubine and couldn't bear to kill her, so he consulted with Gao Lishi and died with the maid. Yang Guifei fled south under the escort of Chen's cronies and arrived in Shanghai by boat today. After drifting at sea for a long time, she moved to Gugu Town, Japan, and finally spent her old age in Japan. However, its life and death are still difficult to understand.
