According to the "General Genealogy of Manchu Clan", Nurhachi's original surname was Jueluo. In the early days of the Aixinjueluo family's rule in the Central Plains, their descendants were not named according to their seniority. Only during the Kangxi period did they begin to adopt the Han method of naming according to their seniority. In the early years of Kangxi, several princes were named after the three characters "Cheng", "Bao" and "Chang". It was not until the 20th year of Kangxi that the character "Yin" was uniformly adopted. Among them, the name of Emperor Kangxi's son Yongzheng was Yinzhen, and Sun "Hong" is used for generations, and "Yong" is used for great-grandchildren. During the Qianlong period, based on a poem he wrote, he decided to use "Yong", "Mian", "Yi" and "Zai" for future generations. During the Daoguang period, "Pu", "Yu", "Heng", and "Qi" were determined, and during the Xianfeng period, "Tao", "Kai", "Zeng", and "Qi" were determined. In 1938, when revising and continuing the Aixinjueluo family genealogy, Puyi added 12 more words, "Jingzhi Kairui, Xiyingyuan Sheng, Zhengzhao Maoxiang". The royal brothers of the Qing Dynasty also had no uniform way of avoiding taboos. After Yinzhen ascended the throne, his brothers changed their names to "Yun", but after his son, Emperor Qianlong Hongli, ascended the throne, his brothers were not required to avoid the name. When Qianlong passed the throne to Yongyan, Yongyan was renamed Yongyan in order to prevent others from changing his name. After Daoguang Emperor Mianning succeeded to the throne, he also changed his name to Minning. The family is huge, so in order to subdivide it, starting from Jiaqing, it was also stipulated that the radicals of the second characters of the same generation and the same lineage should be the same. For example, Emperor Xianfeng's name was Yiqi, and he had half-brothers, such as Yi?, Yi Pei, and Yixuan. The second character of their names was all "Yan". Prince Qing Yikuang, because he was not the son of Daoguang, was from the "Li" department. The family lineage belongs to the generation of the emperor who ascended the throne, the higher the family lineage.
