Gu Lun and Princess Jing are the eldest daughters of your princess, and they should be favored, but the reality is that they are too favored.
According to the princess system of the Qing Dynasty, only the daughter born to the queen is eligible to be named Princess Gulun, and the daughter of the concubine can only be Princess Heshuo.
Although the mother of Gu Lun and Princess Jing was the pure queen of Emperor Xiaoyi, she was not a queen at that time, but a concubine in the harem. It is very obvious that it is not normal for the eldest daughter to be named Princess Gulen.
The titles of Gulen and Princess Jing are unreasonable. Later, it was explained that Gulen and Princess Jing had such titles because she married a good husband and made her worth growing up.
