After Tuyühu Khan departed from the northeast, Murong Wei composed an “Older Brother’s Song,” or “the Song of A Gan:” “A Gan” is Chinese transcription of “a ga” for “older brother” in the Xianbei language. The song lamented his sadness and longing for Tuyühu. Legends accounted that Murong Wei often sang it until he died and the song got spread into central and northwest China. The Murong Xianbei whom he had led successively founded the Former Yan (281-370), Western Yan (384-394), Later Yan (383-407), and Southern Yan (398-410).
