Li Baozhen
As a result of Wang Wujun's removal of his own royal title, Emperor Dezong recommissioned him as the military governor of Chengde Circuit — adding Kang Rizhi's two prefectures to his territory, although not Zhang Xiaozhong's three prefectures. He also soon made Wang the military governor of Lulong Circuit as well, intending to use Wang's ambitions against Zhu Tao. Emperor Dezong also made Wang an honorary chancellor with the designation "Tong Zhongshu Menxia Pingzhangshi" (), made him "Sikong" (司空, one of the Three Excellencies), and created him the Prince of Langye. However, Zhu, unaware of this development, began his plan of march toward Luoyang in early 784. He went through Chengde and Weibo with great ceremonies of welcome from Wang and Tian Yue. Eventually, when Zhu reached Yongji (永濟, in modern Handan) and requested that Tian join him in advancing to Luoyang, Tian refused. This drew Zhu's anger, and he divided his troops, along with Huige troops, in attacking several different Weibo cities. Tian put up his defense at Wei Prefecture, waiting for aid; while he was doing so, he was assassinated and succeeded by his cousin Tian Xu (Tian Chengsi's son), and while Zhu rejoiced at the news and Tian Xu initially made overtures to Zhu, Tian Xu eventually continued Tian Yue's policies, continuing to be allied with imperial forces under Li Baozhen and Ma Sui. Zhu thus continued to siege two primary cities of Weibo — with Zhu himself sieging Bei Prefecture (貝州, in modern Xingtai, Hebei), defended by the Weibo general Xing Caojun (), and Ma Shi sieging Wei Prefecture, but could not capture either. Meanwhile, Li Baozhen and Wang had joined their forces and advanced into Weibo territory. Hearing the news, Ma Shi lifted the siege on Bei Prefecture and joined forces with Zhu. When Zhu prepared to battle Wang and Li Baozhen the next day, Ma Shi, citing the fact that his soldiers at just travelled a substantial distance, requested a few days of rest. However, the Huige general assisting Zhu, as well as Yang Bu () and Cai Xiong, advocated for immediate attack. The next day, May 29, 784, the armies battled, and the overly confident Zhu was defeated by Wang's and Li Baozhen's forces. Over 10,000 of his 30,000 soldiers were killed, and over 10,000 deserted. Zhu, with a few thousand remaining soldiers, feared annihilation at Wang's and Li Baozhen's hands and fled to De Prefecture. Wang and Li Baozhen were unable to give chase because of dense fog. After defeating Zhu, Wang returned to Heng Prefecture and declined the additional title of military governor of Lulong, and Emperor Dezong agreed. Soon, with Wang continuing to attack Zhu, Zhu resubmitted to Tang authority as well.
