Wang Chuzhi
After Wang Rong agreed to become Zhu Quanzhong's vassal, another assistant of his, Zhang Ze (), pointed out that Yiwu and Lulong remained affiliated with Hedong (as, despite the earlier formal break from Li Keyong, Liu Rengong and Li Keyong had assisted each other when under attack from Zhu), and that Chengde needed to continue to worry about a joint attack by all of those circuits. He suggested to Wang that Wang persuade Zhu to attack and conquer Yiwu and Lulong, so that thereafter Chengde would not need to worry about a Hedong attack in coordination with those circuits. Wang therefore had Zhou Shi submit that suggestion to Zhu. Zhu was pleased, and he sent his general Zhang Cunjing () north to attack Lulong and Yichang first, capturing Ying (), Jing (), and Mo () (all in modern Cangzhou) Prefectures. However, after Zhang's path north toward You Prefecture was blocked by flooding, he attacked Yiwu to the west instead. After his troops dealt a crushing blow to Yiwu troops, Wang Gao fled. The remaining Yiwu soldiers supported Wang Chucun's brother Wang Chuzhi as Wang Gao's successor, and Wang Chuzhi subsequently persuaded Zhu to withdraw his troops by agreeing to be a vassal as well.
