I don't understand how a random Jurchen could have become the ruler of North Korea. This dynasty has no connection to kings and emperors. They're just fucking randoms.
Also, I don't understand how the Jurchens can accept this domination when the rulers are basically a no-name family ?
Also, I heard a theory that North Koreans are actually Southerners who were displaced to the North during the war. Because the noble Jurchen blood (North) would never accept such domination by no name
