Apprenticed Chinese martial arts and Beijing-opera skills with Jackie Chan and Sammo Hung Kam-Bo under the same master at China Drama Academy in her younger days, Cheung Cheun Nam (aka Yuen Qiu) has worked briefly as female stunt and night club performer at late 60s to early 70s. Seeing the future for female stunt was not promising, she got married in 1974 at the age of 24 after finishing a small role in her so far one and only one international production, James Bond 007's "The Man with the Golden Gun" (1974). She acted as a girl student rescuing Roger Moore.

Destiny plays its tricks and magic again. Having been off hook from Hong Kong's showbiz for more than 28 years, she starred again in Kung Fu Hustle (2004) just by chance. She was only accompanying a junior woman fellow (of China Drama Academy) at the audition but the director's eye was on her. Reports show that Stephen Chow got her nod after unremitting and persistent persuasion.

Her first grandchild was born in 2004.
Experienced what Renée Zellweger did for "Bridget Jones" productions, she took the Japanese sumo wrestler's diet in order to add 40lbs for "Kung Fu Hustle".
