TV plays are often different from history. It is said that Yongqi was raised by your princess, but this is not the case in history. Although the script story of Yan Xi Palace is somewhat close to history, it is adapted from history, but there is still a certain gap between it and the real history.
In the history books of the Qing Dynasty, there is no mention that Emperor Qianlong's concubine raised May Yongqi, so we can infer that Yongqi was raised by his biological mother Yu Fei. Although it was stipulated in the Qing Dynasty that after the birth of a prince, he could not be raised by his biological mother, there were exceptions to everything. At that time, Yongqi was the only child of Crillet's special family, so the Emperor Qianlong at that time probably allowed her to raise her own son for the sake of Yu Fei, because several children would not seize power from each other in the future.
Historically, Yongqi's biological mother was Colette. At that time, Collert was not favored among so many harem concubines in Qianlong. On the contrary, her mother is very expensive. After Yongqi was born, Emperor Qianlong was happy to promote Colette as Princess of Pleasure. Moreover, Cleette is also one of the longest-lived concubines in Qianlong's harem.
Unfortunately, however, Mei Yongqi died young at the age of twenty-five. After seeing Mei off, the delicious princess looked down on the world of mortals and didn't put the emperor's favor first. Maybe it is because she didn't take the initiative to compete for favor that she can live so long.
