爾朱世隆
In spring 531, Husi Chun participated in Erzhu Shilong's plot to depose Yuan Ye (a distant member of the imperial Yuan clan and Princess Beixiang's nephew, whom the Erzhus had declared emperor during the war against Emperor Xiaozhuang to compete with Emperor Xiaozhuang) and make Yuan Gong the Prince of Guangling, a grandson of Emperor Xianwen, emperor instead (as Emperor Jiemin), and for that participation was created the greater title of Duke of Chengyang. Husi, who became convinced that Erzhu Zhao was being overly violent and autocratic, tried to ask, along with Heba Sheng (賀拔勝), Erzhu Shilong to try to persuade Erzhu Zhao to change his ways. Erzhu Shilong refused and was displeased with the advice. He wanted to kill Husi, but Erzhu Tianguang, another prominent member of the Erzhu clan, interceded and saved Husi.
