田悦
In 776, after the death of Tian Shenyu () the acting military governor of Biansong Circuit (汴宋, headquartered in modern Kaifeng), his subordinate Li Lingyao () seized the circuit without imperial approval. Under Emperor Daizong's orders, the circuits around Biansong all launched forces against Li Lingyao, except for Weibo — indeed, Tian Chengsi decided to aid Li Lingyao and sent Tian Yue with an army to do so. Tian Yue had initial successes, defeating the forces of Li Zhengji's Pinglu Circuit and Li Mian's Yongping Circuit (永平, headquartered in modern Anyang, Henan), enabling him to advance to Biansong's capital Bian Prefecture to try to lift the siege against Li Lingyao. However, once he arrived there, Li Zhongchen had his office Li Chongqian () launch a surprise night attack against Tian Yue's forces, causing the Weibo relief force to collapse, and Tian Yue was forced to flee back to Weibo. Subsequently, Bian Prefecture fell to Li Zhongchen and Ma Sui, and Li Lingyao was captured in flight by Li Mian and executed.
