爾朱世隆
Erzhu Shilong was a cousin of Erzhu Rong and a fellow member of the ethnic Xiongnu Qihu (契胡) tribe, of which Erzhu Rong was chief. (They were at most as close as second cousins, as they did not have the same grandfather.) Unlike Erzhu Rong, who served his entire career as a general and not a civilian official, Erzhu Shilong was part of the imperial administration during the reign of Emperor Xiaoming, although he became a commander of the imperial guards as well.
