The lei tai is an elevated fighting arena, without railings, where often fatal weapons and bare-knuckle martial arts tournaments were once held. "Sanctioned" matches were presided over by a referee on the platform and judges on the sides. Fighters would lose if they surrendered, were incapacitated, or were thrown or otherwise forced from the stage. The winner would remain on the stage (as its "owner") unless ousted by a stronger opponent. If there were no more challengers, they would become the champion. Private duels on the stage had no rules and were sometimes fought to the death.
