All weapons and boxing matches were conducted without protective gear like the "Jissen Kumite" (full-contact fighting) of Kyokushin Karate. On top of being forced from or thrown to the floor of the stage, the fights sometimes continued until either boxer conceded defeat, was severely injured and could no longer fight, or was even killed. One example of a death on stage was described by Hung Gar Grandmaster "Chiu Kow" (1895–1995), father of Grandmaster Chiu Chi Ling. The fight took place between Hung Gar Master "Leng Cai Yuk" and a triad boss named "Ha Saan fu", who was also a master of Internal martial arts. Because Ha dealt in prostitution, gambling, and drugs, Leng challenged Ha to a lei tai bout to halt the expansion of his criminal territory. Ha accepted the challenge and agreed to leave the area if he lost.
