Choi's practices were later renamed to Hapkido [合氣道] and students of Choi Yong Sul, such as Ji Han Jae, the late Myung Kwang-sik, the late Han Bong-soo and others helped to spread this art both inside and outside Korea.

By that time, DongYi refers to Korean, as in Outsiders from the East With the Mongol Conquest of Korea, archery became the main stay of Korean military. The swords and spears of the Korean and Chinese armies did very little to stop Mongol archers and were quickly discarded in favor of the composite bow, which proved to be a much more effective weapon against the
