How did Yang Yuhuan change from Princess Shou to Emperor Xuanzong's pillow?

Forced to become a Taoist woman, and then become a imperial concubine.

When Li Mao, the birthday girl, and Yang Yuhuan fell in love, Wu Huifei died. After her death, Tang Xuanzong felt lonely and sighed all day. At this time, someone told Tang Xuanzong that there was no need to be sad. There is a person who looks like Wu Huifei, and that is the longevity princess Yang Yuhuan.

Tang Xuanzong was very happy to hear this. In fact, he has seen the rich gods of Yang Yuhuan, and he has already felt the surge of emotion surge. In October of the 28th year of Kaiyuan, Emperor Xuanzong of the Tang Dynasty wrote a letter to Yang, a female Taoist priest, in the name of praying for his mother Dou Taihou.

Yang Yuhuan was forced to become a monk, but during this period, Emperor Xuanzong often visited her and loved her very much. At this point, the identity of Princess Shou has been completely cleared. In order to comfort his son, Emperor Xuanzong of the Tang Dynasty named Wei's daughter Princess Shou. After Emperor Xuanzong of the Tang Dynasty took the beauty home, he gathered 3,000 pets, and even the Yang family began to gain power gradually.

Its ending:

In the 14th year of Tianbao (AD 755), Fan Yang, Pinglu and Hedong engaged in an Anshi Rebellion in the name of Jun Qing and Anti-Yang Guo Zhong, and the soldiers directed at Chang 'an. The following year, when Emperor Xuanzong of the Tang Dynasty fled with Yang Guifei and Yang to (now Chengdu, Sichuan) and passed through Mayi Post (now the west of Xingping City, Shaanxi Province), the imperial sergeant led by Chen unanimously demanded the execution of Yang and Yang Guifei, then defected and killed Yang with a knife.

Emperor Xuanzong of the Tang Dynasty said that the imperial concubine was innocent and should be pardoned, but the imperial soldiers all thought that the imperial concubine was the beauty of the country. The Anshi Rebellion was caused by the imperial concubine. Without punishing her, it would be difficult to comfort the morale of the army, boost morale and continue to surround the emperor.

Emperor Xuanzong of the Tang Dynasty accepted Gao Lishi's suggestion and had to give Yang a gift to protect himself. In the end, Yang Guifei was given a white silk and hanged under a pear tree in a Buddhist temple at the age of 38. This is the allusion in Bai Juyi's "Song of Eternal Sorrow": "A soldier in the army will be embarrassed if he doesn't move."
