Han officials of the Ming dynasty (1368–1644) classified them into three groups, reflecting relative proximity to the Ming:

  1. Jianzhou (Chinese: 建州) Jurchens, some of whom were mixed with Chinese populations,[citation needed] lived in the proximity of the Mudan river, the Changbai mountains, and Liaodong. They were noted as able to sew clothes similar to the Chinese, and lived by hunting and fishing, sedentary agriculture, and trading in pearls and ginseng.
  2. Haixi (Chinese: 海西) Jurchens, named after the Haixi or Songhua river, included several populous and independent tribes, largely divided between semi-nomadic pastoralists in the west and sedentary agriculturalists in the east. They were the Jurchens most strongly influenced by the Mongols.
