田弘正
However, Emperor Muzong's transfers backfired, to Tian Hongzheng's detriment, as the Chengde soldiers resented him for the previous warfare between Weibo and Chengde. In fall 821, Chengde soldiers led by Wang Tingcou mutinied and killed Tian Hongzheng and his staff members. Li Su, as Tian Hongzheng's successor, mourned Tian Hongzheng and planned to lead the Weibo soldiers in a campaign to avenge Tian Hongzheng, but fell ill and could not do so. Emperor Muzong thus recalled Tian Bu, who was then observing a mourning period for Tian Hongzheng, to serve as the military governor of Weibo. Tian Bu declined several times, but the imperial government insisted. Tian Bu bid farewell to his wife, children, and household guests, stating, "I will not come back!" He reported to Weibo without the customary fanfare with banners and guards, and while he was still some 30 "li" (roughly 15 kilometers) away from Weibo's capital Wei Prefecture (), he changed into mourning clothes and entered the city in tears. He sold ancestral properties and distributed the proceeds to the soldiers, while turning down his own salary. He also respected the senior officers as if they were his older brothers.
