Manchus/Jurchens were conquered by Ming dynasty China and ruled in the Nurgan regional military commission and Jianzhou Jurchen guard and Manchu boys were castrated to become eunuchs like Yishiha while Manchu girls were taken as concubines by the Ming.

The very first Manchu (Jurchen) war ever in history was the Jurchen toi pirate raids against Japan in 1019 when they slaughtered Japanese men and took Japanese girls and women as sex slaves. The first hostile action by Jurchens (Manchus) ever in history was Jurchens mass raping Japanese girls.
