Wang Dao
In 307, Sima Yue, who had emerged victorious in the aftermaths of the War of the Eight Princes as the regent for Emperor Huai, under the advice of his wife Princess Pei, commissioned Sima Rui as the military commander of parts of Yang Province (揚州, modern Zhejiang and southern Jiangsu and Anhui) south of the Yangtze River, with his post at Jianye. Wang Dao became his chief advisor. As Sima Rui lacked fame, after he arrived in Jianye, few of the powerful local gentlemen would come visit and support him. Under Wang Dao's counsel, Sima Rui personally visited He Xun () and Gu Rong () and invited them to serve in his administration. He and Gu were well regarded by the local population, which eventually began to trust Sima Rui's leadership. Wang Dao and his cousin, the general Wang Dun, served in key roles, and it was said at the time that the domain was ruled equally by the Simas and the Wangs.
