Li Chongjun
Meanwhile, in addition to Empress Wei and Consort Shangguan, Empress Wei's daughter Li Guo'er, the Princess Anle, became very powerful as well, as she was Emperor Zhongzong's favorite daughter, and she had married Wu Sansi's son Wu Chongxun (). She often humiliated her brother Li Chongjun the Crown Prince on account that Li Chongjun was not born of Empress Wei, at times calling him "slave." She also often suggested to Emperor Zhongzong that he depose Li Chongjun and make her crown princess. In summer 707, Li Chongjun's anger erupted, and he, along with the ethnically Mohe general Li Duozuo and Emperor Zhongzong's cousin Li Qianli () the Prince of Cheng, rose in rebellion, first killing Wu Sansi and Wu Chongxun. He then attacked the palace, seeking to arrest Consort Shangguan. Consort Shangguan, Empress Wei, Li Guo'er, and Emperor Zhongzong were protected by the imperial guards, and when Li Chongjun hesitated at what to do next, his forces collapsed, and he and his cohorts were killed.
