王处直
In 910, another major confrontation between Jin and Later Liang began to take shape, as Zhu Quanzhong, believing that his vassal Wang Rong – the Prince of Zhao and the military governor of Wushun Circuit (headquartered in modern Shijiazhuang, Hebei) – might be considering to align with Jin and turning against Later Liang. He therefore decided to, by trick, seize Wushun's Shen (深州) and Ji (冀州, both in modern Hengshui, Hebei) Prefectures and slaughter the Wushun garrisons at those prefectures, with the intent to then use the prefectures as the base for taking over Wushun entirely. When this occurred, Wang Rong and his ally Wang Chuzhi the military governor of Yiwu Circuit (義武, headquartered in modern Baoding, Hebei) turned against Later Liang and sought aid from Li Cunxu. Li Cunxu launched an army to head to the aid of Wang Rong and Wang Chuzhi. Subsequently, in a battle that Li Siyuan served as a battlefield commander, at Boxiang (柏鄉, in modern Xingtai, Hebei), the Jin army crushed the Later Liang army, securing Wushun (which was then changed back to its Tang name Chengde (成德)) and Yiwu from further Later Liang attack.
