an offensive against Zhu Jin, and his chief commander Zhu Zhen captured Cao Prefecture (曹州, in modern Heze, Shandong) and apprehending its prefect Qiu Hongli while Zhang Guiba () routed Zhu Jin in battle at Jinxiang (金鄉, in modern Jining) and overrun Pu Prefecture (濮州, also in modern Heze). An attempt by Zhu Zhen to seize Tianping's capital Yun Prefecture () itself is repelled with loss however, and later both Cao and Pu Prefectures had to be abandoned. Meanwhile, to the south, Gao Pian, military governor of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu), had been killed in a mutiny and the Tang court conferred on Zhu Quanzhong concurrent powers as military governor of Huainan. Zhu Quanzhong sent a deputy, Li Fan (), to take control of the circuit, but on arrival Li Fan found Yang Xingmi, one of Guo Pian's generals, in control of the provincial capital Yang Prefecture (). Yang, while receiving Zhu's emissary Zhang Tingfan (), refused to accept Li Fan as the acting military governor. With Shi Pu the military governor of Ganhua (感化, headquartered in modern Xuzhou, Jiangsu) also displeased because he was not given the Huainan command and launching troops to stop Li Fan and Guo Yan (who was escorting Li Fan) from reaching Yang Prefecture, Zhu had to abandon plans to take over Huainan. Meanwhile, following the defection of one of Qin Zongquan's generals, Zhao Deyin of Shannan East Circuit (山南東道, headquartered in modern Xiangyang, Hubei, renamed Zhongyi () by Tang after Zhao's defection), to the Tang cause, Zhu's armies laid siege to Cai. To purchase supplies for the war against the rebels Zhu sent a military administrator north with 10,000 taels of silver to buy grain from Le Yanzhen, military governor of Weibo Circuit (魏博, headquartered in modern Handan, Hebei). However, this mission coincided with a mutiny of the Le's guard during which Zhu's emissary was killed and the money and any grain he had purchased presumably confiscated. In retaliation Zhu dispatched Zhu Zhen with an army who successfully plundered across Wei territory before returning home. Without support from Zhu, Le's son Le Congxun (), who was a held out against the mutineers, was defeated, and he was executed along with his father, who had tried to avoid being executed by becoming a Buddhist monk; the Weibo officer Luo Hongxin took over Weibo and made peace with Zhu.
