This is why the class system fell into disorder, and Nobi decreased from 37% to 2% in one region, but such event caused a situation that Yangban (traditional ruling class or nobles of dynastic Korea during the Joseon Dynasty) who made up only 9% of the population increased to 70%.
そのため身分制度は混乱し、ある地方では37%居た奴婢が2%まで減少し、代わりに人口の9%に過ぎなかった両班が70%を占めるという状況も起きた。
