Urnala surname is Manchu surname, which is one of the eight Manchu surnames and belongs to Huangzheng Banner of Manchuria. During the Qing dynasty, several queens appeared in the Urals. First, Empress Xiao Liewu is the fourth princess royal of Joan's great-grandfather Nurhachi and the biological mother of Dourgen. Secondly, Yong Zhengdi's wife, Urana, gave birth to a son and died young. The successor queen of Emperor Qianlong was also Unara, who was also the first imperial concubine to set up the Sixth Palace in the Qing Dynasty. However, after her death, she was buried with imperial concubine etiquette, and there was no state funeral for three years, which made her experience even more foggy.

Urana, the heir of Emperor Qianlong, is called the most wronged queen. She was chosen as a side Fujin when Emperor Qianlong was still a prince. According to historical records, the Emperor Qianlong at that time had no love for the queen who succeeded him, and a series of things later accumulated, which led to the tragedy of Queen Urnala.

It was not the emperor Qianlong's opinion to choose Urnala as the queen, because the emperor Qianlong had no feelings for Urnala at that time, but the queen mother especially liked Urnala, so Qianlong made Urnala the queen according to his mother's orders. Because of this incident after the establishment, the gap between the emperor and Ulan Nala has deepened.

Urnala is stubborn, and many things don't know how to reverse Gankun, which makes the emperor very disgusted with her, especially when he had an argument with Emperor Ganlong on his fourth southern tour and broke his hair. In the Qing dynasty, if a woman broke her hair, it meant a curse, which made the emperor very angry. The specific reason for the broken hair, because there is no historical record, can not be verified now, especially after Nora's death, Emperor Qianlong deliberately erased her traces. Urnala was a sentimental person, but she also knew that Emperor Qianlong had no feelings for her, so she was very sad and finally made a decisive move.
