The actor, whose real name was Kwan Ning, affectionately known as Ha Shuk, was born in Hong Kong in 1926. Kwan learned the art of Cantonese opera acting from his father as a child, and entered show business when he was 11.
He was recruited by renowned Cantonese opera stars Yam Kim-fai and Bak Shuet-sin through their famous Sun Sing opera troupe, having performed in Hong Kong, Macau and Vietnam.
From 1950 to 1960, Kwan was a key character in many films, including Lee Rock and Hard-Boiled.
He joined Television Broadcasts in 1976 and acted in scores of television dramas including Shu Kim Yan Sau Luk (1976), Lau Man Tai Hang (1986) and Wong Fei Hung Xi Lie Zhi Yi Tai Shi (1992).
At the 11th Hong Kong Film Awards in 1992, Kwan was named best supporting actor for his role in Lee Rock.
The actor suffered a stroke in early 2001, which confined him to a wheelchair and forced him to retire.
