Nian Gengyao (1679~ 1726), a good worker with double peaks, was originally from Huaiyuan, Anhui Province, Han nationality, and was a general of the Qing Dynasty. Nian Gengyao's wife is the daughter of Nalan Xingde. The second room is the daughter of lord protector Su Yan, the assistant of the imperial clan. Nalan Xingde (1655- 1685), a native of Manzhouli, Rong Ruo, was one of the most famous poets in Qing Dynasty. Na Lanxing's mother is Aisingiorro Xi, the daughter of Azig, and her father, Na Lanmingzhu, has served as the head of the Ministry of Internal Affairs, the official department minister, and the university student of Wuyingdian. Nalanxingde has four daughters. The second daughter, Gu, married Nian Gengyao, a bachelor's assistant in imperial academy, which means Nalanxingde is Nian Gengyao's father-in-law. In the 45th year of Kangxi, Nian Gengyao married the second daughter of Nalan Xingde. However, Nalan Nalan Xingde died young in 1685 (twenty-four years of Kangxi), that is to say, when Nian Gengyao got married, Nalan was already dead, so Nalan Xingde was not a father-in-law for a day. Nian Gengyao continues to marry the daughter of Su Yan, the descendant of the imperial clan King Azig (note that she is also a wife rather than a concubine), so Su Yan is the only person who can be Nian Gengyao's father-in-law.
