In 1956, due to poor academic performance and possibly poor conduct, he was transferred to St. Francis Xavier's College, where he would be mentored by Brother Edward, a teacher and coach of the school boxing team. Lee was involved in several street fights, his parents decided that he needed to be trained in the martial arts. Lee's friend William Cheung introduced him to Ip Man but he was rejected from learning Wing Chun Kung Fu under him because of the long standing rule in the Chinese Martial Arts world to not teach foreigners. His one quarter German background from his mother's side would be an initial obstacle towards his Wing Chun training; however, Cheung would speak on his behalf and Lee was accepted into the school.Lee began training in Wing Chun with Yip Man. Yip tried to keep his students from fighting in the street gangs of Hong Kong by encouraging them to fight in organized competitions. After a year into his Wing Chun training, most of Yip Man's other students refused to train with Lee when they had learned of his mixed ancestry, as the Chinese were generally against teaching their martial arts techniques to non-Asians. Lee's sparring partner, Hawkins Cheung, states, "Probably fewer than six people in the whole Wing Chun clan were personally taught, or even partly taught, by Yip Man". However, Lee showed a keen interest in Wing Chun and continued to train privately with Yip Man, William Cheung and Wong Shun Leung.In 1958, Bruce won the Hong Kong schools boxing tournament, knocking out the previous champion, Gary Elms, in the final. That year, Lee was also a cha-cha dancer, winning Hong Kong's Crown Colony Cha-Cha Championship.
