Lu Kai
In 266, Sun Hao split the office of Imperial Chancellor into two, and appointed Wan Yu as Right Imperial Chancellor (右丞相) and Lu Kai as Left Imperial Chancellor (左丞相). The reason for splitting the office was that he wanted Wan Yu to balance against the influential and more senior Lu Kai. In the spring of 267, Sun Hao ordered Wan Yu to supervise military affairs in Jing Province and station at Baqiu (巴丘; present-day Yueyang, Hunan), effectively replacing Lu Kai, who had been performing that task for years.
