In order to become a champion, a fighter had to defeat countless opponents. For instance, Lama Pai Grandmaster Wong Yan-Lam set up his own lei tai platform in front of "Hai Tung" Monastery in Guangdong after having worked as a famous bodyguard in Northern China. For 18 days, he fought over 150 other martial artists and was never defeated. According to Hop Gar Grandmaster David Chin, "Either the challenger was maimed or killed. Wong never let one challenger leave his school without injury. He was a master of using the technique of cruelty." Shortly afterwards, he was elected as the leader of the Ten Tigers of Canton, who were the top ten kung fu men in Guangdong. Eighteenth generation Chen-style t'ai chi Grandmaster Chen Zhao Pi (陈照丕) (1893–1972), third nephew of Chen Fake, set up a platform by Beijing’s “Xuan Wu Men” city gate after an unauthorized article claiming the superiority of Chen-style t'ai chi appeared in the "Beijing Times", causing many martial artists to challenge his skills. Over the course of 17 days, he defeated over 200 people and made many friends. If these examples are followed, it took a fighter anywhere from 17–18 days and 150-200 plus consecutive wins to establish their style's dominance in that area.
