慕容徳
Fu Jiān made most Former Yan princes commandery governors in his empire, and both Murong De and his brother Murong Na were commissioned as such, but Murong Na was soon removed from his office, and both Murong Na and their mother Consort Gongsun relocated to Murong De's post at Zhangye Commandery (張掖, roughly modern Zhangye, Gansu). Around or in 383, when Fu Jiān prepared a campaign to destroy Jin and unite China, Murong De and his troops were mobilized, and he left his own sons, Murong Na, and Consort Gongsun in Zhangye; before leaving, he gave his mother a golden knife as a sign of his devotion.
