Sima Daozi
Empress Dowager Li's influence during Emperor Xiaowu's reign appeared to be limited, as Emperor Mu's mother Empress Dowager Chu was regent early, and after she gave up regent authorities in 376, power was largely in the hands of Xie An until Emperor Xiaowu fully turned adult. She was described as often mediating conflicts between him and Sima Daozi, and throughout his reign, Sima Daozi had great authority as the emperor's brother and prime minister.
