Li Hui (李回), né Li Chan (李躔), original courtesy name Zhaohui (昭回), later changed to Zhaodu (昭度), formally Duke Wenyi of Longxi (隴西文懿公), was a Chinese politician of the Chinese Tang dynasty, serving as a chancellor during the reign of Emperor Wuzong.
[3] As of 843, Emperor Wuzong was preparing a major campaign against the warlord Liu Zhen, who had taken control of Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi) without imperial sanction after the death of his adoptive father (and biological uncle) Liu Congjian, who had served as Zhaoyi's military governor.
[3][6] (It was also said that part of Li Hui's mission was to alleviate the adversarial relationship between Zhang and one of the imperial generals, Liu Mian (劉沔) the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi).
Under Li Deyu's proposal, which Emperor Wuzong accepted, Emperor Wuzong's son Li Qi (李岐) the Prince of Yan was nominally made the supreme commander over six circuits (i.e., the six circuits affected by the Dangxiang incursions) and chief comforter of the Danxiang.
[8] Li Hui, meanwhile, remained as chancellor and oversaw the building of Emperor Wuzong's tomb, but in 847 was also sent out of the capital to serve as the military governor of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan).
That winter, with Li Deyu accused of having wrongly killed Wu Xiang (吳湘) on charges of corruption and forced marriage with a commoner—a case that both Li Hui and Zheng Ya were both involved in reviewing and affirming the death sentence of—Li Hui was demoted to be the governor (觀察使, Guanchashi) of Hunan Circuit (湖南, headquartered in modern Changsha, Hunan) and prefect of its capital Tan Prefecture (in modern Changsha, Hunan).
Emperor Xuānzong was then set to further give him the empty title of Taizi Binke (太子賓客), an advisor to the Crown Prince (there being no crown prince at the time) and having his office at the eastern capital Luoyang,[7][9] when an imperial attendant objected to it as being an overly lenient punishment.
[3][7] (It was from Emperor Xuānzong's edict that it could be attested that Li Hui carried the title of Duke of Longxi, which was not otherwise mentioned in his biographies.)
