Tian Xu
However, Zhu Tao, unaware of this development, began his plan of march toward Luoyang in early 784. He went through Hengji and Weibo with great ceremonies of welcome from Wang and Tian. 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 (邢曹俊), 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 (楊布) 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. Zhu executed Yang and Cai and decided to return to You Prefecture, where he had left his cousin Liu Peng in charge—but as he did so, he feared that Liu would take advantage and seize power. However, when he returned to You Prefecture, Liu mobilized the remaining troops and exited the city to welcome him in grand ceremony.
