Zhao Yanshou
It is not known when Zhao Yanshou—then carrying the birth surname of Liu and probably already using the personal name Yanshou—was born. However, it is known that his birth father Liu Yuan () served as the magistrate of Xiu County (蓨縣, in modern Hengshui, Hebei), and that his mother was a Lady Zhong. Sometime during the "Kaiping" era (907-910) of Zhu Quanzhong the emperor of Later Liang, Zhao Xingshi, then an officer under Liu Shouwen the military governor ("Jiedushi") of Yichang Circuit (義昌, headquartered in modern Cangzhou, Hebei), raided Xiu and captured both Liu Yanshou and his mother Lady Zhong. Zhao then took Liu Yanshou as an adoptive son.
