Li Chongjun
Despite this irreverence, Emperor Zhongzong did not rebuke her. He did, however, make her brother Li Chongjun, born of a concubine, crown prince. Both Li Guo'er and her husband Wu Chongxun looked down on Li Chongjun, however, and at times they even called him "slave". In summer 707, in anger, Li Chongjun rose in rebellion with the ethnically Mohe general Li Duozuo and Emperor Zhongzong's cousin Li Qianli () the Prince of Cheng. Li Chongjun killed Wu Sansi and Wu Chongxun, but in his subsequent attack on the palace was defeated and forced to flee; he was then killed in flight.
