After the founding of the country, he appointed his mother as the queen and his concubine as the imperial concubine.Because he successively conquered many beautiful women in his room, such as Huáng, the mother of Huáng in the western frontier and Yan Zhenqi, known as the female Qilin in the southern border, and so on. Therefore, the world privately called him Emperor Yuzhu.
