爾朱兆
Meanwhile, the other members of the Erzhu clan were also growing corrupt, particularly Erzhu Zhongyuan. The general Gao Huan, who had been a follower of Erzhu Rong, believed that the Erzhus could be overthrown, and rebelled in summer 531. The members of the Erzhu clan were largely unconcerned, due to Gao's inferiority in numbers, but Erzhu Shilong, knowing Gao's abilities, was concerned. Gao soon declared another distant member of the imperial Yuan clan, Yuan Lang, emperor. When the Erzhu forces converged at Guang'a (廣阿, in modern Xingtai, Hebei) to face Gao, Gao used false rumors to make them suspicious of each other—by making Erzhu Zhao believe that Erzhu Shilong and his brothers were conspiring against him, and by making Erzhu Shilong and Erzhu Zhongyuan believing that Erzhu Zhao was conspiring with Gao. As a result, after a major quarrel between Erzhu Zhao and Erzhu Zhongyuan, Erzhu Zhongyuan and Erzhu Rong's cousin Erzhu Dulü (爾朱度律) withdrew, leaving Erzhu Zhao, albeit with still a much larger army than Gao's, alone against Gao. Gao subsequently defeated him, and, brushing his army aside, continued to advance south, entering the important city Yecheng in spring 532.
