Mahiyan
The Mahiyan are the Jurchen group of the Mayan river, whose Manchu name refers to its elbow-like bends; it rises in the Zhangguangcai mountains and winds through Shangzhi, Yanshou and Fangzheng to join the right bank of the Songhua. They were among the Wild Jurchens brought under Later Jin rule in Nurhaci's campaigns of 1596 to 1625.
