Yu Zhong (于忠) (462 – 21 April 518[1]), né Wuniuyu Qiannian (勿忸于千年), courtesy name Sixian (思賢), formally Duke Wujing of Lingshou (靈壽武敬公), was an official of the Northern Wei dynasty.
Wuniuyu Qiannian was born from a line of Northern Wei nobles of Xianbei ethnicity.
Wuniuyu Qiannian himself became a low level official during the regency of Emperor Xiaowen's stepgrandmother, Grand Empress Dowager Feng.
When Empress Gao wanted to put Emperor Xiaoming's mother Consort Hu to death, Yu, Cui, the eunuch Liu Teng (劉騰), and the general Hou Gang (侯剛), protected Consort Hu by hiding her.
Yu and Cui soon forced Empress Gao to confer regent authorities on Emperor Xuanwu's uncle Yuan Yong the Prince of Gaoyang and Emperor Xiaowen's cousin Yuan Cheng (元澄) the Prince of Rencheng, and when Gao Zhao subsequently returned to the capital Luoyang from a military campaign against rival Liang Dynasty that Emperor Xuanwu had commissioned, Yu and Yuan Yong ambushed him and put him to death.
The officials Pei Zhi (裴植) and Guo Zuo (郭祚), who were unhappy about Yu's authoritarian acts, secretly suggested to Yuan Yong to have Yu removed from his post and sent to a province to be governor.
