Soon thereafter, after Lan Mu had won a victory over Lan Ti and Lan Jia'nan, Lan Han held a feast for the soldiers, at which both he and Lan Mu became extremely drunk. Murong Sheng used this opportunity to join some army officers whom he had persuaded to join his cause, and they killed Lan Han and Lan Mu, and then Lan Ti, Lan Jia'nan, and Lan Han's other sons Lan He () the Duke of Lu and Lan Yang () the Duke of Chen. Murong Sheng then declared Later Yan's restoration and took the throne, but in order to show humility, did so with his present title of Prince of Changle, rather than claiming imperial title immediately.
