Wu Chongyin

Wu Chongyin (烏重胤) (761 – November 30, 827), courtesy name Baojun (保君), formally Duke Yimu of Zhangyi (張掖懿穆公), was a general of the Chinese dynasty Tang Dynasty.

Wu Chongyin was born in 761, during the reign of Emperor Suzong. His father Wu Chengbi (烏承比) was an army officer at Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi). From Wu Chongyin's youth, he served as an officer at Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi).

As of 810, Wu Chongyin was serving under then-military governor (Jiedushi) of Zhaoyi, Lu Congshi (盧從史), in a campaign declared by Emperor Suzong's great-great-grandson Emperor Xianzong against the warlord Wang Chengzong the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei), which Lu had initially encouraged Emperor Xianzong to engage in. Once the campaign was underway, however, Lu was in secret communication with Wang and interfered with the progress of the imperial forces, commanded by the eunuch general Tutu Chengcui. After this was revealed by Lu's staff member Wang Yiyuan (王翊元) to the chancellor Pei Ji, Tutu persuaded Wu to join his plan to act against Lu. Tutu endeared himself to Lu by offering Lu a number of precious gifts; after Lu's guard was down, Tutu had Lu seized while the two were at a feast in the army camp. When Lu's soldiers were set to act against Tutu, Wu rebuked them, and they did not dare to do so, but followed Wu's orders.

Tutu put Wu temporarily in charge of the Zhaoyi forces, and Emperor Xianzong contemplated making Wu the military governor of Zhaoyi, before, at Li Jiang's advice, he shifted Wu to Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan) while making Heyang's military governor Meng Yuanyang (孟元陽) the military governor of Zhaoyi. In 814, Wu's headquarters was moved to Ru Prefecture (汝州, in modern Pingdingshan, Henan), which was added to Heyang Circuit, in anticipation of a campaign against another warlord, Wu Yuanji, who took control of Zhangyi Circuit (彰義, headquartered in modern Zhumadian, Henan) without imperial approval after the death of Wu Yuanji's father Wu Shaoyang.
