西燕
In 393, when Murong Chui considered conquering the rival claimant (to rightful succession to Former Yan) Murong Yong of Western Yan, most officials opposed the proposal, arguing that the troops were worn out. Murong De was one of the few who agreed with the proposal, reasoning that Murong Yong was causing confusing among the people as to who was the legitimate successor. Murong Chui agreed, and in 394 carried out campaigns that led to Western Yan's destruction.
