慕容宝
Princess Lan was the daughter of Lan Han the Prince of Dunqiu and his wife Lady Yi. It is not known when she married Murong Sheng, but as of 398, she carried the title of princess, because Murong Sheng was the Prince of Changle under the reign of his father Murong Bao (Emperor Huimin). That year, after a rebellion secretly instigated by Lan Han, Murong Bao and Murong Sheng were forced to flee from the capital Longcheng (龍城, in modern Jinzhou, Liaoning). During that flight, Princess Lan was described to have carefully served her mother-in-law, Murong Bao's concubine Consort Ding. Later that year, Lan Han laid a trap for Murong Bao and tricked him into believing that he was still faithful to Murong Bao, and then as Murong Bao approached Longcheng, he had Murong Bao killed. He then took over the throne.
