Huan Wen
In 369, the Jin general Huan Wen launched a major attack against Former Yan, defeating each Former Yan army sent against him and advancing all the way to Fangtou (枋頭, in modern Hebi, Henan), near Yecheng. Murong Wei and Murong Ping panicked and considered fleeing to the former capital Longcheng. However, Murong Chui volunteered to make one last stand against Huan Wen, and he and his brother Murong De were able to deal Huan a major defeat. Relief forces from Former Qin (which Former Yan requested) then arrived, and together they dealt Huan another major defeat, ending Huan's hopes of destroying Former Yan.
