Tian Chengsi
In 775, Zhu Tao, per mandate of Emperor Daizong, attacked Tian Chengsi the military governor of Weibo Circuit (魏博, headquartered in modern Handan, Hebei), along with Li Baochen the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei). Because Liu was loved by the army, Zhu put him in command of headquarters before launching his campaign. Tian, however, persuaded Li Baochen to turn against Zhu, and late in 775, Li Baochen launched a surprise attack on Zhu's army and then attacked north, hoping to capture Lulong's headquarters. However, with Li Baochen realizing that Liu had taken precautions, he stopped his attack.
