Yu Liang
After Sima Yan took the throne (as Emperor Cheng), several officials who were named in Emperor Ming's will were put in charge—that included Wang Dao, Sima Yang (司馬羕) the Prince of Xiyang, Bian Kun (卞壼), Chi Jian, Yu Liang, Lu Ye (陸瞱), and Wen Jiao. However, quickly, Yu Liang, as the brother of Emperor Cheng's mother Empress Dowager Yu, became effectively the most powerful among them, as Empress Dowager Yu became regent. Wang's role in government continued to be important, however.
