Koreans also referred to the Jianzhou Jurchen guard lands north of the Yalu and Tumen rivers as part of China. The name Jianzhou is Chinese. The Koreans were enemies of the Ming in the early 1400s and tried to buy the loyalty of the Jianzhou Jurchens away from China.
Manchus changed their ethnic group's name from Jurchen to Manchu hide their history of subjugation to Ming China. The Ming ruled the Jianzhou Jurchen for 200 years and used Jurchen tribes to kill each other.

This change was made to obscure the fact that his ancestors had been under Chinese rule and that they are referred to in Chinese records as Ju-chên or Chien-chou.The Ming ruled the Jurchen in the Nurgan Regional Military Comission and the Jianzhou Jurchen guard with a Ming general controlling Jurchen tribes and appointing Jianzhou Jurchen chiefs.
There were Jurchen concubines and Jurchen eunuchs like Yishiha in the Ming palace after the Ming conquered the Jurchen and they were castrated. The Ming ruled the Jurchen in the Nurgan Regional Military Comission and the Jianzhou Jurchen guard.
