Wei Cong (éÂÂç®), courtesy name Liyu (禮çÂÂ), was an official of the Chinese Tang dynasty, serving briefly as a chancellor during the reign of Emperor XuÃÂnzong (reigned 846 â 859).
It is not known when Wei Cong was born, and little is known about his background â as there was no biography of his in the Old Book of Tang, and his biography in the New Book of Tang merely stated that he came from a line of prominent officials, while omitting his ancestry entirely in its table of the chancellors' family trees, not listing him among the other chancellors of the Wei clan.
According to the New Book of Tang, Wei Cong passed the imperial examinations in the Jinshi class, and eventually served as an imperial censor with the title Dianzhong Shiyushi (殿ä¸Âä¾Â御å²). While serving in that post, he was considered to have made incorrect conclusions in criminal investigations, and was instead made Taichang Boshi (太常åÂÂ士), a scholar at the ministry of worship (太常寺, Taichang Si). After several promotions, he was eventually made the deputy minister of census (æÂ¶é¨ä¾ÂéÂÂ, Hubu Shilang) and chief imperial scholar (ç¿°æÂÂå¸士æÂ¿æÂ¨, Hanlin Xueshi Chengzhi).
In 847, during the reign of Emperor XuÃÂnzong, Wei Cong was made Zhongshu Shilang (ä¸ÂæÂ¸ä¾ÂéÂÂ), the deputy head of the legislative bureau of government (ä¸ÂæÂ¸çÂÂ, Zhongshu Sheng), and chancellor de facto with the designation Tong Zhongshu Menxia Pingzhangshi (Ã¥ÂÂä¸ÂæÂ¸éÂÂä¸Â平章äºÂ). He was not a capable chancellor, however, and because of that, later in the year, he was removed from his chancellor position and made an advisor to the Crown Prince, with his office at the eastern capital Luoyang. He died while serving there.
