 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.
