Why did Yang Guifei lose her mind?

Maweipo

Xuanzong Yang Guifei returned to Chang 'an Yang, the dragon was dead, and the country with unforgettable old feelings began to revitalize.

The execution of Yang Fei was also a wise decision of Xuanzong, otherwise it would lead to the country's demise.

Maweigang, Maweipo, is located in Xingping, Shaanxi. The Anshi Rebellion in Tianbao period of Tang Dynasty was called Anshi Rebellion. In the fifteenth year of Tianbao, the rebels in An Lushan broke through Tongguan, and the soldiers pointed to Chang 'an (that is, Tik Tok was very hot, and Xi Anmin train was under the wall of Xi Anmin. . . . )。 Li Longji, Emperor Xuanzong of the Tang Dynasty, fled hastily. All the way westbound, when passing through Mayi Post, General Chen thought that the country was divided here because of consort Yang. The guards mutinied and demanded the execution of Yang and Yang Guifei. It's really unfortunate since ancient times.

The first sentence of the above poem "Xuanzong returns to the horse" means that the rebellion has been put down. At this time, Tang Xuanzong, who was already the emperor's father, returned to Chang 'an from Sichuan. The first sentence says that the world is stable, Xuanzong returns, and Yang Guifei drives a crane to the west. The contrast between life and death shows that Xuanzong's safe return is at the expense of Yang Guifei's life. Of course, Li Longji, Emperor Xuanzong of the Tang Dynasty, still loved Yang Guifei very much. Day by day passed, but the pain of apologizing for Yang Guifei accompanied him for the rest of his life.

After all, Li Longji is a generation of wise men. He knows what to do at the critical moment, but he quotes the story of Jingyang Palace in Chen Houzhu for comparison, which is intriguing.
