In 405, after Murong De, who had by then established Southern Yan and become its emperor, had become aware that Murong Chao was being detained in Chang'an, he sent secret messengers to encourage him to flee to Southern Yan. Murong Chao did not dare to tell even his mother and wife, and fled to Southern Yan. As Murong De had no surviving sons, he made Murong Chao his crown prince, and after he died later that year, Murong Chao succeeded him as emperor.
