庾亮
In fall 325, Emperor Ming grew ill. He entrusted his four-year-old son, Crown Prince Yan, to a group of high-level officials, including Sima Yang (司馬羕) the Prince of Xiyang, Wang Dao, Bian Kun (卞壼), Chi Jian, Yu Liang, Lu Ye (陸瞱), and Wen Jiao, perhaps intending that they lead by group with a balance of power. He died soon thereafter—only 26 years old. The balance of power that he left was soon broken, however, as Empress Dowager Yu became the regent, and her brother Yu Liang became the most powerful of the officials, eventually offending Su Jun and Zu Yue into a rebellion that damaged Jin for years.
