Zong Chuke
Meanwhile, there had been accusations made by individuals such as Lang Ji () and Yan Qinrong () that Empress Wei was committing adultery, and that her partisans, including Li Guo'er, her new husband Wu Yanxiu (武延秀, a grandnephew of Wu Zetian), and Zong Chuke, were planning to overthrow the Tang dynasty. Emperor Zhongzong ordered Lang executed, but became displeased when Zong had Yan killed without Emperor Zhongzong having decided to do so. This caused Empress Wei and her partisans to begin to become apprehensive. Empress Wei was, meanwhile, having affairs with the officials Ma Qinke () and Yang Jun (). She wanted to be Empress Regnant like Wu Zetian, and Li Guo'er wanted to be crown princess—a request that Emperor Zhongzong had repeatedly rebuffed. According to traditional historians, they thus decided to have Emperor Zhongzong killed. They accomplished this by putting poison in a cake, and after Emperor Zhongzong ate the cake, he died on 3 July, 710.
