daughter Li Guo'er, who now carried the title of Princess Anle and formed a faction that wielded strong control over the court and consolidated her power. The only mother-daughter rival for dominate the emperor's grace and power was the Emperor Zhongzong's sister, Princess Taiping, who also had great favor with Emperor Zhongzong and was one of the most powerful women in the court. Also powerful was Wu Zetian's secretary Shangguan Wan'er, whom Emperor Zhongzong took as a concubine, who was also having an affair with Wu Zetian's nephew Wu Sansi the Prince of Liang. Under her introduction, Empress Wei and Wu Sansi also soon started having an affair. With Consort Shangguan's and Empress Wei's influence, Wu Sansi became a powerful and trusted advisor to Emperor Zhongzong. Meanwhile, Empress Wei, disliking Emperor Zhongzong's oldest surviving son Li Chongfu the Prince of Qiao (born of a concubine), falsely accused Li Chongfu of being complicit in Li Chongrun's death.

(Also buried there were Emperor Zhongzong's brother Li Xián, Li Chongrun, and Li Xianhui.) In spring 706, after Emperor Zhongzong's son-in-law Wang Tongjiao (王同皎, husband of Princess Ding'an), who despised Empress Wei and Wu Sansi, was accused of plotting to kill Wu Sansi and depose Empress Wei, Wang and his alleged coconspirators were executed, and subsequently, Wu Sansi and his associates accused Jing Hui, Huan Yanfan, Zhang Jianzhi, Yuan Shuji, and Cui Xuanwei of being complicit in Wang's plot. The five princes were exiled and subsequently died or were killed in exile. In 707, Li Chongjun, angry that Li Guo'er and her husband Wu Chongxun (武崇訓, Wu Sansi's son) had repeatedly humiliated him and tried to
