Wang Wujun
Chengde Army Jiedushi was one of the Three Fanzhen of Hebei after the An Lushan Rebellion. From 762 it was headquartered in Heng Prefecture (恆州)/Zhen Prefecture (鎮州) (Zhengding, Hebei), and controlled Heng, Ji, Shen, Zhao, De, and Di prefectures. Its territory were primarily located in Shijiazhuang, Zanhuang, and Hebei. Li Baochen, adopted son of An Lushan, was in charge of Heng Prefecture under An Qingxu. He surrendered to Tang and retained control over central Hebei east of the Taihang Mountains. Li Weiyue requested succession of Chengde Army in 781 and was denied, so he rebelled, and was killed a year later by his subordinate general Wang Wujun. Han Lingkun, Wang Chengzong, Wang Tingcou were "jiedushi" of the Chengde Army.
