Zhang Yizhi
Meanwhile, Wu Zetian, in her old age, had entrusted much of the affairs of state to Zhang Yizhi and Zhang Changzong—something that Li Chongrun discussed with his sister Li Xianhui and her husband, Wu Zetian's grandnephew Wu Yanji (武延基) the Prince of Wei (Wu Chengsi's son) at times. Zhang Yizhi found out and informed Wu Zetian. Wu Zetian, believing that she was being criticized, in fall 701, ordered Li Chongrun, Li Xianhui, and Wu Yanji to commit suicide. Li Chongrun's death would leave Crown Princess Wei without a son, as his other sons Li Chongfu, Li Chongjun, and Li Chongmao were all born of concubines.
