The mystery of Yang Guifei: Was she hanged at Mawei or did she sail to Japan?

Yang Guifei is one of the most renowned beauties in Chinese history, and her love story with Emperor Xuanzong of the Tang Dynasty has been passed down through generations. There has always been controversy surrounding whether she truly died by hanging at Mawei Post Station. According to Tang Dynasty literature, it is indeed recorded that Yang Guifei was hanged there. However, numerous legends suggest that she did not die at that location but rather escaped through various means. Bai Juyi's poem "Song of Everlasting Regret" mentions that she vanished from her grave at Mawei, sparking curiosity about her fate. In the early 20th century, scholars proposed various hypotheses, including the possibility that she fled to Japan, became a Taoist priestess, or lived in the imperial court. These theories continue to perplex people regarding the fate of Yang Guifei.
