Wang Chuzhi
In fall 900, Zhu himself launched a major attack on Chengde and Yiwu Circuit (義武, headquartered in modern Baoding, Hebei), whose military governor Wang Gao was an ally of Li Keyong's. He first forced Wang Rong to submit, and then attacked Wang Gao. When Zhu defeated Wang Gao's uncle Wang Chuzhi, Wang Gao abandoned Yiwu and fled to Hedong. The Yiwu soldiers subsequently supported Wang Chuzhi to take over the circuit and sue for peace with Xuanwu by submitting to Zhu. During Zhu's campaign, Li Keyong tried to relieve the pressure on Yiwu by sending Li Sizhao to attack Zhu's Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan). Li Sizhao quickly captured Heyang's Huai Prefecture (懷州, in modern Jiaozuo, Henan) and then put Heyang Circuit's capital Heyang under siege. However, he was subsequently repelled by the Xuanwu officer Yan Bao () and forced to withdraw.
