Geng Jingzhong
The "Dolo efu" 和碩額駙 rank was given to husbands of Qing princesses. 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 (耿昭忠) become court attendants under the Shunzhi Emperor and married Aisin Gioro women, with Prince Abatai's granddaughter marrying Geng Zhaozhong 耿昭忠 and Haoge's (a son of Hong Taiji) daughter marrying Geng Jingzhong. A daughter 和硕柔嘉公主 of the Manchu Aisin Gioro Prince Yolo 岳樂 (Prince An) was wedded to Geng Juzhong 耿聚忠 who was another son of Geng Jingmao. Aisin Gioro women were offered to Mongols who defected to the Manchus. The Manchu Prince Regent Dorgon gave a Manchu woman as a wife to the Han Chinese official Feng Quan, who had defected from the Ming to the Qing. Feng Quan willingly adopted the Manchu queue hairstyle before it was enforced on the Han population and Feng learned the Manchu language.
