During his time living with Ip Man, Cheung introduced a then 15–year–old famous child actor, Bruce Lee, whom he first met at Lee's 9th birthday to Ip Man. Originally Ip Man had rejected Bruce the right to learn 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.
