Wang Dao
Initially, Yu tendered many resignations to the emperor, his nephew. Wang Dao, as regent, turned those resignations down in the emperor's name and but instead commissioned Yu as the governor of Yu Province (豫州, by that point referring to modern central Anhui). After Tao's death in 334, Yu succeeded him as the governor of Jing (荊州, modern Hubei and Hunan), posted to Wuchang (武昌, modern Ezhou, Hubei), Yu, and Jiang Provinces and the military commander of the western provinces. Even though he was not in control of the government, but he continued to have great influence from his post as the emperor's uncle.
