The evocation plot in Song of Eternal Sorrow is mainly inspired by the story of Li Furen, the emperor of the Han Dynasty. There is such a poem in Bai Juyi's Song of Eternal Sorrow: "Lin qióng Taoist Hongdu (46) can concentrate. People were moved by the emperor's persistent meditation, and then taught alchemists to be diligent. " It is said that a famous Taoist priest visited Chang 'an in Qionglai, Sichuan (now called Qionglai City in Lin Qiong) and could use magic to recall his soul. But Tang missed Yang Guifei so much that he quickly asked the Taoist priest to do it. In Song of Eternal Sorrow, the Taoist recruited Yang Guifei and even gave her a bright future. Yang Guifei went to live in Xianshan overseas and lived happily. She only sent a letter and a collection to Don.
