He Qi
In 216, Cao Cao granted You Tu, a local leader in Poyang Commandery (鄱陽郡), the seal of authority and instigated him to start a rebellion. Three counties in Poyang Commandery responded to You Tu's call. In response, Sun Quan ordered He Qi and Lu Xun to suppress the rebellion, which they did and killed several thousands of rebels. After that, He Qi remained at the border along the Yangtze River between Sun Quan and Cao Cao's territories to guard against any enemy invasion.
