Dong Zhang
In 923, Li Cunxu declared himself the emperor of a new Later Tang. At that time, Li Shaobin carried the title of commander of the guard corps from Zhending (真定, in modern Baoding, Hebei), serving under Li Cunxu himself. That year, Li Jitao, the son of Li Cunxu's deceased cousin Li Sizhao, surrendered Anyi Circuit (安義, headquartered in modern Changzhi, Shanxi), to Later Liang's then-emperor Zhu Zhen. Li Jitao's subordinate Pei Yue () the prefect of Ze Prefecture (澤州, in modern Jincheng, Shanxi) refused to follow his betrayal of Later Tang, but was subsequently put under siege at Ze by the Later Liang general Dong Zhang. Pei sought emergency aid from Li Cunxu, who sent Li Shaobin to aid him, with the explicit instructions to make saving Pei the first priority — that the city may be given up if Pei could be saved. However, before Li Shaobin could arrive, the city had already fallen, and Pei was killed.
