Wei Zi protects your princess.

As we all know, Emperor Qianlong had three empresses in his life. The first one was Fu Cha, the queen of Bai Yueguang, whom Emperor Qianlong never forgot, and the second one was Nora, who was succeeded by Queen Fu Cha after her death, but she never got the favor of Emperor Qianlong. Later, Queen Nora was seized power because of the broken hair incident, and the power of the harem fell to the imperial concubine favored by Emperor Qianlong, but the imperial concubine was only the imperial concubine before her death. This is because of Emperor Qianlong. First of all, your concubine is the queen who has given Ganlong the most children. The imperial concubine is one of the most special concubines in Qianlong harem. Your concubine is Han nationality, originally from Wei family. Later, Emperor Qianlong raised the flag into Manchu Zhenghuang Banner and changed it to Wei Jiashi. Wei Jiashi, the daughter of manager ouchi, entered the palace for the first time as a maid-in-waiting. Later, because of his outstanding appearance, he was favored by Emperor Qianlong, thus becoming a noble person of Wei, and was later promoted to a concubine and soon canonized as a princess. Later, the imperial concubine gave birth to four emperors for Qianlong and was promoted to the imperial concubine. Then she gave birth to nine emperors and became the imperial concubine. The imperial concubine gave birth to four sons and two daughters for Qianlong in her life and became the queen who gave birth to the most children for Emperor Qianlong.

Then, because of Qianlong's excessive love, your princess became a imperial concubine before her death. According to historical records, the imperial concubine was forty years old when she gave birth to her last child, so she can still serve her bed at such an advanced age. This shows how much Gan Long loves your concubine, but she has been managing the harem for more than ten years, but she has not been canonized as a queen. This is because Emperor Qianlong likes your concubine too much and doesn't want to hurt her. We all know that in the Qing dynasty, when there was a queen, the imperial concubine would not be appointed, because it would put a lot of pressure on the queen. At that time, when Queen Nora was in power, Qianlong conferred the title of the imperial concubine, which shows that Qianlong really liked the imperial concubine very much. However, a broken hair incident happened at that time, which made Qianlong afraid that he loved your princess so much. If you make your princess queen, it is equivalent to announcing that your princess's son in the world is the next monarch. So, in order not to hurt the person you like, you didn't become a queen.

Finally, although your concubine didn't have the title of queen before her death, she was treated as a queen. After her death, Qianlong made her the filial piety queen and became the third queen of Emperor Qianlong.
