Yang Shihou
In 897, Wang Gong attacked Wang Ke. Wang Ke sought aid from Li Keyong, while Wang Gong sought aid from Li Keyong's archenemy Zhu Quanzhong the military governor of Xuanwu Circuit. The Xuanwu forces, commanded by Zhu's generals Zhang Cunjing (張存敬) and Yang Shihou, were initially successful against Huguo forces, but the Hedong relief forces, commanded by Li Keyong's nephew Li Sizhao, then defeated Baoyi forces and lifted the siege against Huguo.
