Wei Yuanzhong
In 707, Emperor Zhongzong's crown prince Li Chongjun, born of a concubine, was angry that Empress Wei's daughter Li Guo'er the Princess Anle was repeatedly insulting him and trying to become crown princess to displace him, started a rebellion and killed Wu Sansi and Wu Sansi's son Wu Chongxun (武崇訓, also Li Guo'er's husband). He subsequently marched on the palace, hoping to arrest Li Guo'er, Empress Wei, and Emperor Zhongzong's concubine Consort Shangguan Wan'er. Li Jiao was one of the officials who commanded imperial guards in countering Li Chongjun's attack, and Li Chongjun was eventually defeated and killed. Thereafter, Wei Yuanzhong, by this point a senior chancellor, was accused of association with Li Chongjun by Zong Chuke and Ji Chuna, and Li Jiao and Yang went along with Zong's and Ji's accusations; Wei was eventually exiled and died in exile.
