Sima Zhao
In 255, when the Wei generals Guanqiu Jian and Wen Qin started a rebellion in Shouchun (壽春; present-day Shou County, Anhui), Sima Shi led Wei imperial forces to suppress the revolt, with Zhong Hui accompanying him as an assistant officer. Sima Shi's younger brother, Sima Zhao, followed behind with another army to support them. Sima Shi died in Xuchang after the rebellion was suppressed. He was succeeded by Sima Zhao, who took over command of his troops. At the time, the Wei emperor Cao Mao ordered Sima Zhao to remain in Xuchang and Fu Jia to lead the armies back to the imperial capital, Luoyang. Zhong Hui conspired with Fu Jia to urge Sima Zhao to disregard the emperor's order and lead the troops to a garrison at the south of the Luo River () near Luoyang. Sima Zhao became the new regent and continued to remain in control of the Wei government as his brother did before him. Zhong Hui was appointed as a Gentleman of the Yellow Gate () and awarded the title "Marquis of Dongwu Village" () with 300 taxable households in his marquisate.
