"Shang Nai Mei Lu led the noble concubine to the Buddhist hall and hanged her."
The Zizhi Tongjian has made yang Yuhuan's ending very clear, and Yang Yuhuan died at the hands of the eunuch Gao Lishi. Later, in order to appease the indignant soldiers, Li Longji also asked Chen Xuanli and others to confirm Yang Guifei's death.

According to the theory, Yang Guifei's life should come to an end at this point, but some good people are not willing to let the beauty end with such an ending, they turn the period into a question mark, and according to literary works such as "Long Hate Song", a series of suspense is introduced.
Some people say that Li Longji did not kill Yang Yuhuan at all, but quietly let her go, and since then Yang Yuhuan has been exiled to the people and fallen into the wind and dust; others say that Yang Yuhuan was not killed, but went to Japan to settle in anonymity.
The former claim is absurd and lacks support, and there is no record of it in the history of the wild; the latter is clearly transmitted from Japan, and the relevant evidence is also provided by the Japanese.
At a cursory glance, Yang Yuhuan's eastward crossing to Japan seems to have a true matter, but if you think about it carefully, this is not logical at all, and it is obvious that this statement is suspected of "export to domestic sales", and it may be made up by the Japanese.
First of all, none of the physical evidence produced by the Japanese is directly related to Yang Yuhuan, and it is impossible to verify whether it is true or false. As for the so-called witnesses, it is even more ridiculous to laugh off their teeth and casually stand up and call themselves the descendants of Yang Yuhuan, which is too outrageous. Although the "Yang Guifei Guanyin Hall" and "Yang Guifei Tomb" in Japan do indeed exist, why is there no record of these two places in The Japanese historical materials that are even a few words?
Secondly, several authoritative historical materials that have been elevated to the height of "History of Faith" have proved that Yang Yuhuan did die in Ma Songyi, and these historical materials unanimously determine that Yang Yuhuan died at the age of thirty-eight. The Old Book of Tang has this record: "The emperor returned himself to Shu, ordered the envoys to pay tribute, and ordered the burial." Li Shuyi ( Li Shuyi ) said, "The Dragon Warriors are loyal to the country, and they are responsible for the chaos of the country." Now that the old concubine is buried, I am afraid that the soldiers will be suspicious, and the funeral will not be feasible!' It's over. The Emperor's secret order made the envoys to be buried in him. When it first fell, it was wrapped in purple mattresses, and the skin was broken, and the sachet was still there. This record can be said to be direct evidence that Yang Yuhuan died in Ma Songyi.
What kind of information can we get from this historical data?
First, it is a fact that Yang Yuhuan xiang died of jade, otherwise Li Longji would not have bothered to send people to pay tribute every year, and later reburied him;
Second, the matter of rebury caused dissatisfaction among the soldiers, so this matter had to be carried out in extreme secrecy;
Third, after Li Longji's commissioner dug up Yang Yuhuan's tomb, he found sachets and other funerary items from it, which was in line with the records in the New Book of Tang;
Fourth, after opening the coffin, the commissioner found that the former noble concubine had "disappeared with jade face."
Many people have misinterpreted the meaning of "jade face is not seen" and feel that Yang Yuhuan's body disappeared out of thin air. If Yang Yuhuan's body really disappeared, what should be the explanation for "skin is broken"? Since Yang Yuhuan's body and burial items are in the coffin, how can Yang Yuhuan run to Japan to live in seclusion? Taking ten thousand steps back, even if Yang Yuhuan faked her death in the Ma Songyi incident and successfully ran to Japan, then she would not be able to leave an heir. Because, Yang Yuhuan has no fertility at all!
Yang Yuhuan married at the age of seventeen, and died when Shaohua was thirty-eight years old. In these twenty-one years, she has accompanied two men successively, but her stomach has never moved. Obviously, Li Longji and Li Mao are very sound men, and their fertility is no problem. If it is said that when Yang Yuhuan accompanied Li Longji, the elderly Li Long's genetic body aged and lost his fertility, then why did Yang Yuhuan not give birth to a son to Li Mao?
The year Li Mao married Yang Yuhuan was at the golden age of eighteen. The two have been together day and night for ten years, and Yang Yuhuan has not been able to give birth to a child for Li Mao, why is this? Li Mao and other concubines gave birth to many children, which is enough to show that Li Mao has fertility. It can be seen that all the roots are in Yang Yuhuan's body, and she has no fertility at all. Therefore, Yang Yuhuan, who was unable to give birth at all, did not have the opportunity to conceive an heir.
Is there any famous doctor in Japan who can cure the infertility problem that the Tang Dynasty imperial doctors can't solve?
Obviously this is not possible.
Therefore, the article "Yamaguchi Baihui is a descendant of Yang Yuhuan" written by the good deeds is pure fiction.
So, what is the significance of the birth of this article?
The author specifically looked for information before and after the publication of the article, and found that not long after this article was published, the film and television work "Tang Ming Huang" came into being. Is this a coincidence? I don't think so. It is estimated that in order to cooperate with this film and television work, such an irresponsible but rather gimmicky article was deliberately written, which played a role in hype.
