There was indeed a Princess Xi in Yongzheng period, which was the background of Zhen Xuan's creation. Princess Xi of Yongzheng entered the palace through the draft during the reign of Kangxi, and Kangxi named her Gege and betrothed her to Yin Zhen, the fourth son of the emperor at that time. After Yongzheng ascended the throne, Princess Gege joined Feng. There is such a record in the Collection of China's Letters during the Yongzheng period: Gege Qian is called Fei.
Therefore, Yongzheng's fee is Han Chinese, surnamed Qian. According to historical records, Princess Xi was named the Imperial concubine of Xi in the eighth year of Yongzheng, and her position in the harem was second only to that of the Empress Zhonggong. In the ninth year of Yongzheng, the queen died of illness, and Xi Guifei became the head of the harem and the Lord of the harem.

During the reign of Kangxi, Yongzheng suffered from epidemic disease, and his condition was very serious, and he almost died. Niu Zhilu is diligent in serving, cooking soup and medicine, and is very thoughtful. In the fiftieth year of Kangxi (17 1 1), the fourth son of the emperor was born in Yonghe Palace on August 13th.
When Li Hong was ten years old, he served Emperor Kangxi with his father in the early years of Yongzheng and gave a banquet at the Peony Pavilion in Yuanmingyuan. When Emperor Kangxi saw that Sun Hongli was brilliant and liked him very much, he took him to the palace to study and raise him personally, and called Li Hong "a great blessing". Lian said that Niu Zhilu is a blessed man. To this end, Niu Zhilu was more favored by Yongzheng. ?
Prince Yong ascended the throne as Yong Zhengdi. On the 14th day of the first month of Yongzheng, Niu Zhilu was made a princess, and on December 22nd of the same year, the princess held a conferring ceremony. In the eighth year of Yongzheng, he was promoted to Xi Guifei, but he did not accept the conferring ceremony.
In August of the first year of Yongzheng (1723), Yong Zhengdi secretly built the Crown Prince, wrote the name of Li Hong, and put it on the "aboveboard" plaque in Gan Qing Palace. Li Hong ascended the throne at the age of 25.
