Li Chongjun
Meanwhile, Emperor Zhongzong had created his son Li Chongjun, by a concubine, crown prince, as Empress Wei's only son Li Chongrun had been killed by Wu Zetian in 701, but Li Guo'er, encouraged by Wu Chongxun, had designs on becoming crown princess, and repeatedly asked Emperor Zhongzong to make her crown princess. Both she and Wu Chongxun also repeatedly insulted Li Chongjun, sometimes calling him "slave." In fall 707, Li Chongjun, in anger, started a rebellion with the generals Li Duozuo, Li Sichong (李思沖), Li Chengkuang (李承況), Dugu Yizhi (獨孤禕之), and Shazha Zhongyi (沙吒忠義), as well as Emperor Zhongzong's cousin Li Qianli (李千里) the Prince of Cheng and Li Qianli's son Li Xi (李禧) the Prince of Tianshui. They attacked Wu Sansi's mansion and killed Wu Sansi, Wu Chongxun, and some of their relatives. Li Chongjun's subsequent attempt to reach the palace and arrest Consort Shangguan, Empress Wei, and Li Guo'er, however, were unsuccessful, and his troops collapsed; he was killed. Li Chongjun was beheaded, and his head was presented to Wu Sansi's and Wu Chongxun's caskets. Wu Sansi and Wu Chongxun were buried in grand funerals, and Wu Sansi was posthumously recreated the Prince of Liang with the posthumous name of Xuan (宣, "responsible"). After Emperor Zhongzong's death in 710, a coup led by Princess Taiping and Li Dan's son Li Longji the Prince of Linzi overthrew Empress Wei and restored Emperor Ruizong to the throne, and Wu Sansi's tomb was destroyed.
