In the view of a famous korean scholar named Quan Haizong (全海宗) ,the Sino-Korea relationship was defined as tributary relationship ,pre tributary relationship and untributary relationship . During Ming Dynasty and Qing Dynasty, the Sino-Korea relationship was defined as typical tributary relationship.
