Tian Hongzheng
In 812, when another ally of Li Shidao's, Tian Ji'an the military governor of Weibo Circuit (魏博, headquartered in modern Handan, Hebei), his relative Tian Xing (later known as Tian Hongzheng) took over and submitted to imperial authority. Li Shidao later threatened to, along with Wang Chengzong, attack Tian Hongzheng, but Han Hong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan), who was loyal to the imperial government, threatened to attack him if he attacked Weibo, and Li Shidao did not do so.
