Pei Yan
In 689, still bearing grudges against Wei Xuantong, who was a friend of Pei Yan, a chancellor that Empress Dowager Wu had executed in 684 on suspicions that he opposed her, Zhou falsely accused Wei of having said, "The empress dowager is old. It is better to support the emperor, for he will last longer." In anger, Empress Dowager Wu ordered Wei to commit suicide. Zhou also falsely accused the general Heichi Changzhi the Duke of Yan of treason, and Heichi was strangled to death.
