Juru Hoton
Juru Hoton, known in Chinese as Shuangchengzi, lay in the Suifen valley near the Sea of Japan. Its Jurchen inhabitants lived in former Jin territory that had passed to the Yuan by 1337.
The Ming later administered the coastal Jurchens through the Nurgan regional military commission. The local people were counted among the Wild Jurchens; between 1596 and 1625 Nurhaci's campaigns brought the coast and its tribes under Later Jin rule; the area later passed to the Qing.
