Meanwhile, Tian Hongzheng (a relative of Tian Ji'an's, who had died in 812) the military governor of Weibo — under whose governance Weibo had become imperial territory — stationed his forces near Weibo's borders with Chengde. Wang Chengzong repeatedly harassed his troops, and in anger, Tian requested permission to attack Chengde territory. Emperor Xianzong agreed, and Tian advanced into Chengde territory, but did not advance far. Emperor Xianzong also ordered Zhenwu forces to join Yiwu forces in attacking Chengde. In response, Wang pillaged the territories of Lulong, Henghai (橫海, headquartered in modern Cangzhou, Hebei), and Yiwu. Those circuits advocated a campaign against Wang, and Emperor Xianzong agreed, over the objection of the chancellor Zhang Hongjing, who thereafter resigned. Another chancellor who also opposed the campaign, Wei Guanzhi, was soon exiled. However, it was said that of the six circuits ordered to attack Chengde (Hedong, Lulong, Yiwu, Henghai, Weibo, and Zhaoyi), most of the forces did not advance far, although Zhaoyi's military governor Chi Shimei () scored some victories over Chengde forces. When Hun Gao () the military governor of Yiwu advanced deep into Chengde territory as well, Wang responded by sending operatives into Yiwu territory to burn Yiwu's towns and villages, causing Yiwu soldiers to become fearful for their families. He subsequently defeated Hun, and Hun fled back to Yiwu and was subsequently replaced by another general, Chen Chu (). He also cut off the communications lines between Henghai's capital Cang Prefecture () and Henghai troops, under the command of its military governor Cheng Quan (), forcing Cheng's withdrawal.
