Tian Chengsi
After Li Baochen died in 781, Li Baochen's son Li Weiyue requested imperial sanction to succeed him, but Emperor Daizong's son and successor Emperor Dezong refused, and subsequently, Li Weiyue, along with his allies Tian Yue (Tian Chengsi's nephew, who had succeeded Tian Chengsi in 779), Li Na, and Liang Chongyi, prepared to wage war against the imperial government, and the imperial government responded in kind. Emperor Dezong commissioned Zhu to attack Li Weiyue from the north, and Zhu did so; his victories eventually caused Li Weiyue's subordinate Wang Wujun to assassinate Li Weiyue and surrender.
