Wang Dao
In fall 325, Emperor Ming grew ill. He entrusted the four-year-old Crown Prince Yan to a group of high-level officials, including Sima Yang () the Prince of Xiyang, Wang Dao, Bian Kun (), Chi Jian, Lu Ye (), Wen Jiao, and Empress Yu's brother Yu Liang, perhaps intending that they lead by group with a balance of power. He died soon thereafter. Crown Prince Yan took the throne as Emperor Cheng.
