田弘正
After Wang submitted to imperial orders, Li Shidao also offered to surrender three of his 12 prefectures and submit to imperial orders, but soon reneged on the offer. Emperor Xianzong thus declared a general campaign against Li Shidao. During the campaign, Tian Hongzheng offered to immediately attack Li Shidao, but Pei, pointing out to Emperor Xianzong that if he did so, per regulations at the time, the Weibo soldiers would have to be supplied by the imperial treasury immediately. He thus suggested that Weibo soldiers be kept at Weibo until winter 818. Emperor Xianzong agreed, and when Tian finally launched his attack in winter 818, the attack was effective and crossed the Yellow River into Pinglu territory. In spring 819, Li Shidao's subordinate Liu Wu killed Li Shidao and surrendered Pinglu to imperial control.
