The reflex bow had been the most important weapon for Koreans in wars with Chinese dynasties and nomadic peoples, recorded from the 1st century BC. Legend says the first king and founder of the Goguryeo, Go Jumong, was a master of archery, able to catch 5 flies with one arrow. Bak Hyeokgeose, the first king of the Silla, was also said to be a skilled archer. The ancient Chinese gave the people of the North-East (eastern Siberia, Manchuria and the Korean Peninsula) the name of Dongyi () (Eastern part of the Four Barbarians ()), the latter character () being a combination of the two characters for "large" () and "bow" ().
