Why can the Urnala family be queen when they haven't given birth for 16 years?

First of all, because of her strong position and family background, she can help the court affairs, and the other is the will of Emperor Qianlong's mother, so even if she didn't give birth to a prince in 16, she can still sit on the position of queen. Who's the queen? Under one person, above ten thousand people. ? And many concubines in the palace have been waiting for this position for a long time, and they do not hesitate to rely on various means to try their best to get ahead in the palace and occupy a higher position. For concubines, of course, the most favorable thing is? Is mom expensive? His son was loved and valued by the emperor and had the opportunity to sit on the position of queen. There is such a queen in history, 16 years without children, but she still became a queen. What is the reason? Urnala was the queen of Qianlong, but when Qianlong was a prince, she was just a side blessing, and the emperor didn't like Urnala very much. Because after Qianlong ascended the throne, his first Fujin was made queen, and the other Fujin was also made your wife. Although Urnala is also a side Fujin, only Urnala has been made a princess, so we can clearly see that Qianlong is not very interested in Urnala. But on the one hand, Urnala can sit on the throne of the queen, thanks to the help of Qianlong's mother, that is, Zhen Xuan in "The Concubine in the Palace", because she thinks Urnala is more virtuous and decent than other concubines, with less intrigue and less care. She is fit to sit on the queen's throne and control her son. Of course, on the other hand, there are families behind the Urnala family. If they please the Urnala family, they will serve the court more sincerely, prevent some rebellious things from happening and make their country more stable.
