According to legends recorded in the
Records of the Grand Historian by
Sima Qian, Yuxiong descended from the mythical
Yellow Emperor and his grandson and successor
Zhuanxu. Zhuanxu's great-grandson Wuhui was put in charge of fire by
Emperor Ku and given the title
Zhurong. Wuhui's son
Luzhong () had six sons, all born by
Caesarian section. The youngest son
Jilian adopted the ancestral surname
Mi and had a son named Fuju (). Xuexiong was Fuju's son. However, Sima Qian mistakenly believed Xuexiong and Yuxiong were two different people and that Yuxiong was Xuexiong's descendant. ==Enfeoffment==
