Wen Qin
In 255, declaring that they had received a secret edict from Empress Dowager Guo, Guanqiu Jian and Wen Qin made a failed attempt to overthrow Sima Shi, by starting a rebellion from Shouchun (壽春; present-day Shou County, Anhui). There was no real evidence that Empress Dowager Guo was actually in communication with them, however.
