the Jin dynasty, the Jin Jurchens did not regard themselves as the same tribes as the Hurka people who became the Huligai. Uriangqa was used as a name in the 1300s by Jurchen migrants in Korea from Ilantumen because the Uriangqa influenced the people at Ilantumen. Bokujiang, Tuowulian, Woduolian, Huligai, Taowan separately made up 30,000 households and were the divisions used by the Yuan dynasty to govern the people along the Wusuli river and Songhua area. In the Jin dynasty the Shangjing route 上京路 governed the Huligai. A Huligai route was created as well by the Jin. In 1388, the Hongwu Emperor established contact with three tribes of Ilan Tumen in modern Yilan County near the confluence of the Mudanjiang River and the Songhua River. The Odori, Huligai (Hūrha or Hurka) and Tuowen Jurchens were enlisted as allies against the Mongols. Jurchens began accepting Ming titles. Ahacu, chief of the Huligai, became commander of the Jianzhou Guard in 1403, named after a Yuan Dynasty political unit in the area. Möngke Temür (猛哥帖木儿) of the Odoli became the leader of the Jianzhou Left Guard and accepted the Chinese surname of Tong not long afterward. The two Jianzhou guards engaged in trade with the Ming at the designated market of Kaiyuan and Fushun. They undertook several short-term moves west, battling the Wild Jurchens of the north and the Koreans to their south. Jurchen raids into Korean territory brought about joint Korean-Ming counterattacks in 1467 and 1478 which severely weakened the Jianzhou Jurchens. Jianzhou Jurchens adopted agriculture during the Ming dynasty when they acquired knowledge of fertilization, draft animals, and iron plows as they moved south closer to Asian agricultural civilizations. Iron-smelting and mining knowledge was acquired by the Jurchens from 1599 after they bought iron plowshares from the Chinese and learned how to turn iron into weapons from Koreans. Confederation building By the mid-sixteenth century, the Ming guard structure had mostly disappeared and the Jurchens were split between two confederations: the Haixi Jurchens and the Jianzhou Jurchens. The Jianzhou confederates continued to live north of the Yalu River in five tribes: the Suksuhu River tribe, Hunehe, Wanggiya, Donggo, and Jecen. Under the leadership of Wang Gao, the confederation raided the Ming frontier and even killed the Ming commander at Fushun in 1473. A major counterattack by the Chinese ended in the death of Wang Gao and the dissolution of the confederation. In
