 Meanwhile, Li Keju and Wang Rong the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) both feared Li Keyong's power and his alliance with Wang Chucun, who had married his nephew Wang Ye (王鄴) to Li Keyong's daughter.In spring 885, Li Keju and Wang Rong thus decided to attack Wang Chucun's Yiwu Circuit and divide it among themselves, while persuading Helian Duo to attack Li Keyong so he could not come to Wang Chucun's aid.Li Keyong nevertheless sent Kang Junli to aid Wang Chucun, and subsequently went to Wang Chucun's aid himself.
