耿精忠
The Jurchens under Nurhaci had classified people as Han Chinese (Nikan) according to whether they were former Ming subjects, behaved like Han Chinese, had a Chinese lifestyle, spoke Chinese language, dressed like Han Chinese, and had Han Chinese names, and all Jurchens who had moved to Ming China adopted Chinese surnames. Chinese Bannermen (Hanjun, or Han Bannermen) rose to many powerful positions and prominence under Shunzhi, these Chinese Bannermen (Hanjun, or Han Bannermen) were descendants of Han defectors in Liaodong who joined Nurhaci and Hong Taiji, in the third or second generation. They "were barely distinguishable from Manchu nobility." Geng Zhongming, a Han bannerman, was awarded the title of Prince Jingnan, and his son Geng Jingmao managed to have both his sons Geng Jingzhong and Geng Zhaozhong become court attendants under Shunzhi and married Aisin Gioro women, with Haoge's (a son of Hong Taiji) daughter marrying Geng Jingzhong and Prince Abatai's granddaughter marrying Geng Zhaozhong.
