Chajeon Nori, occasionally translated as Juggernaut Battle, is a traditional usually played by men, originating in the Andong region. It may have originated as a commemoration of Wang Geon's victory over Gyeon Hwon at the (Andong) in 930, near the end of the Later Three Kingdoms period. It resembles a jousting match, with the two commanders are atop large log frames maneuvered by their teams. These trapezoidal log frames are known as dongchae, and are composed of two 10-meter-long logs tied together with straw rope. The dongchae lie horizontally at the beginning of play, but then are hoisted up by their team. Some members of the team carry the dongchae, while others fight with the opposing team to help their side advance.
