田弘正
By 819, during the reign of Emperor Xianzong, when Tian Hongzheng was serving as military governor and was following imperial orders in attacking the warlord Li Shidao, who ruled Pinglu Circuit (平盧, headquartered in modern Tai'an, Shandong), Shi Xiancheng served as Tian's forward commander in leading 4,000 soldiers across the Yellow River to attack Pinglu. With Weibo forces pressuring Pinglu's capital Yun Prefecture () directly, Li's subordinate Liu Wu killed Li and surrendered. As a result of Shi's contributions, he was given the honorary title of deputy chief imperial censor (御史中丞, "Yushi Zhongcheng").
