Murong Nong
Lan Han was an uncle of Murong Bao's father Murong Chui (Emperor Wucheng), the founding emperor of Later Yan, as a younger brother of his mother Consort Lan (although some references indicate that he was her cousin, not her brother), and in 384 he assisted Murong Chui's son Murong Nong in starting a rebellion against Former Qin to assist Murong Chui's main rebellion. During Murong Chui's reign he was sparsely mentioned in history. In 387 he was one of the commanders in a Later Yan campaign against Jin. In 391 he commanded a force against a chieftain of the Xianbei Helan (賀蘭) Tribe, Helan Ran'gan (賀蘭染干). During Murong Chui's reign, he married one of his daughters to Murong Sheng, then the Duke of Changle. As of 395 Lan Han was referred to as the Prince of Yangcheng and was defending Jicheng (modern Beijing). (This reference, however, may be in error, as in 396, after Murong Chui had died and been succeeded by Murong Bao, a cousin of Murong Chui's, Murong Lan (慕容蘭), was referred to as the Prince of Yangcheng and defending Jicheng, so it could have been that both references were supposed to be to Lan Han or neither was.)
