Cui Yin
It is not known when Fang Gao was born, but it is known that he was from the Tang Dynasty capital Chang'an. In his youth, he served on staff at the mansion of the Tang chancellor Cui Yin. According to the "Old History of the Five Dynasties", he later took up residence at Hezhong Municipality (河中, in modern Yuncheng, Shanxi) due to a disturbance. (This might be referring to Cui's death at the hands of the major warlord Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan), in 904.)
