William Cheung

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.

In 1984 Cheung set a world speed punching record of 8.3 punches per second at Harvard University in Boston.

Over a 28-year period Cheung has been featured on the front cover of 35 magazines between 1982 and 2010, the first being Inside Kung Fu in October 1982 and the most recent Martial Arts Illustrated in April 2010.

He also trained Anthony Arnett who has been winning martial arts tournaments since 1974 and has won grand champion multiple times some of which were for 3 years and 6 years running in different tournament circuits.

After moving to Melbourne, Australia to teach Traditional Wing Chun professionally in 1973, Cheung established his Wing Chun studio in Melbourne's CBD. According to The Sydney Morning Herald, his studio attracts hundreds of new students each year. Early in 1976 Cheung participated in the formation of the Australian National Kung Fu Federation and became its president. The federation ran the Australasian Kung Fu Championships from circa 1977/1978. These were the earliest Australian full contact tournaments open to all styles of martial arts.

In the 1950s, Cheung grew up in Kowloon, where fighting skills were considered a measure of self-worth and pride. At age 11, Cheung's challenge matches were on the school playground, and his fighting style was Tai Chi Chuan, which was not sufficient to elevate him among the youth of Hong Kong. This fighting was a concern and was frowned upon by his father, who was a police inspector; hence, Cheung avoided becoming involved in gangs. By his teenage years however the challenge fights continued, and—as they are inextricably linked to extortion rackets of secret societies—Cheung's high-achieving family saw him as a source of embarrassment.
