This has to start from the mystery of Yang Guifei's corpse, after Yang Guifei's death, Tang Xuanzong thought about it day and night and wanted to sleep all day long, so he sent people to Ma Songyi to look for Yang Guifei's body, but it was not found for half a day, at that time, there were rumors that Yang Guifei did not die but fled to Japan, and the Japanese also took this opportunity to publicize the news of Yang Guifei's exile in Japan, and it is said that he was saved by an envoy who sent Tang Guifei.
In the Anshi Rebellion, Yang Guifei should have died on the way to flee to Shudi: Ma Songpo, the rebels at that time also confirmed that the deceased was indeed Yang Guifei, and their purpose was very clear, although Li Longji was still emperor at that time, but his power was different from in the past, and Yang Guifei's work could not be exchanged for his peaceful body. In addition, from various historical records, Yang Guifei did die, and Yang Guifei's death could not be exchanged for the reappearance of Sheng Tang, and this truth Li Longji should be clear, although he did not even give up Yang Guifei's death, but there was nothing he could do...
History records that Emperor Tang Ming loved Yang Guifei very much. Bai Juyi, a great poet of the Tang Dynasty, wrote a famous long poem called "Long Hate Song", which recorded the history of the Ma Songpo Mutiny and the life-and-death parting of Emperor Tang Ming and Yang Guifei. From this, it can be speculated that Li Longji, as emperor, could watch his beloved concubine being strangled to death, and was the so-called hanging of Yang Guifei a deception, in order to stabilize the hearts of the army?
Therefore, there is a saying that Yang Guifei crossed to Japan in the east. It is said that the commander of the army, Chen Xuanli, loved and pitied Yang Guifei's beauty, and could not bear to kill, so he conspired with Tang Xuanzong's heavy minister Gao Lishi to replace him with a maid.
Judging from the later historical records, Yang Guifei is already dead, and Li Longji has missed many times.
Appearing in Japan is purely fictional, and there may be Japanese admirers, that is, fans. Because the Japanese were not so developed when they were emperors of the Tang Dynasty, it was good that they could take a look at Yang Guifei, it was impossible to be around the royal family, and it was even more impossible to steal it.
