慕容宝
As soon as Murong Bao left Longcheng, however, his general Duan Sugu (段速骨) started a rebellion, and the army abandoned Murong Bao, who immediately fled back to Longcheng. Meanwhile, Duan, having forced Murong Long's son Murong Chong (慕容崇) the Prince of Gaoyang as leader, besieged Longcheng. Even with secret help from Lan Han the Prince of Dunqiu—Murong Chui's uncle—however, Duan was initially unsuccessful, until Murong Nong inexplicably surrendered to him, destroying morale and causing Longcheng to fall. Murong Bao and Murong Sheng fled south and, in the confusion, Lan took over Longcheng and offered to receive Murong Bao back. Murong Bao, who had reached Jicheng (modern Beijing) by this point, wanted to head back, but Murong Sheng persuaded to try to head south to seek aid from Murong De, not realizing that Murong De had declared independence. Once they reached the vicinity of Huatai, however, they heard about how Murong De had assumed imperial powers and therefore fled back north. Many cities on the way offered to coalesce around Murong Bao to start a new resistance against Northern Wei, but Murong Bao resolved to head back to Longcheng. Murong Sheng, suspecting that Lan Han was up to no good, tried to persuade Murong Bao otherwise, but was unable to get him to change his mind, and Murong Sheng fled and hid.
