慕容盛
Murong Sheng, who had been suspicious of his father-in-law's intentions and therefore did not join his father's procession back to Longcheng, now decided to arrive at Longcheng to mourn his father, judging correctly that Lan Han would not kill him both because he was Lan's son-in-law and because he pitied Murong Sheng for the destruction of his clan. As Murong Sheng arrived at Longcheng, his wife Princess Lan further bowed not only to her father but her brothers as well, begging for Murong Sheng's life, and she was joined by Lan Han's wife Lady Yi. Lan Han therefore spared him. Murong Sheng soon managed to sow seeds of suspicion between Lan Han and his brothers Lan Jia'nan and Lan Ti (蘭堤). He created his son Lan Mu (蘭穆) crown prince.
