 In light of this joint victory, Erzhu Zhao and Gao swore to be brothers, and he, trusting Gao's faithfulness, gave the remnants of the rebel Ge Rong (葛榮), largely ethnic Xianbei, to Gao—a decision that he would regret later.In spring 531, after Yuan Ye arrived in Luoyang, Erzhu Shilong and Erzhu Tianguang, believing that Yuan Ye was too distantly related to the line of recent emperors and lacking in good reputation, forced Yuan Ye to yield the throne to Yuan Gong the Prince of Guangling (who took the throne as Emperor Jiemin).Because Erzhu Shilong did not first consult with Erzhu Zhao, Erzhu Zhao became angry and considered attacking Erzhu Shilong.
