Jianzhou Jurchens
One of the most vivid narratives and depictions of the Jianzhou comes from a passage supplied by Sin Chun-li. Sin Chun-li’s mission to the Jianzhou Jurchens was aimed to resolve the incident of 1594, in which the Jianzhou Jurchens captured at least seventeen Koreans and were being held for ransom. To resolve the issue, Sin was dispatched by the Korean court to Nurgaci's capital at Fe Ala. He and a small party of Korean officials crossed the Yalu river at Mamp Ojin, and followed a tributaries northwest to the Suksu Valley where Nurhaci was based.
