慕容盛
She gave birth to Murong Sheng while Murong Bao was serving as a low-level Former Qin official, in 373. What happened to her during the next three decades were not clear, but at the time when Murong Bao, then emperor of Later Yan, and Murong Sheng were fleeing from rebellions in 398, she was at the capital Longcheng (龍城, in modern Jinzhou, Liaoning). At this time, she was carefully served by her daughter-in-law Princess Lan, despite the fact that Longcheng was under the control of Princess Lan's father Lan Han, who would set a trap for Murong Bao and have him killed later that year, and then claim the throne. Murong Sheng was spared, however, because he was Lan Han's son-in-law, and he soon overthrew Lan Han in a coup and reestablished Later Yan as its emperor.
