Wong received an MPhil degree from the University of Hong Kong in 1983 for his study in Cantonese opera.

In May 2003, in the midst of his fight with lung cancer,[8] he obtained a PhD degree from the Department of Sociology, University of Hong Kong.

The title of his thesis was "The Rise and Decline of Cantopop : A Study of Hong Kong Popular Music (1949–1997)".

While well known and praised for his creative works in the entertainment and advertisement fields, Wong was also famous for his vulgar and indelicate jokes.

He was regarded as responsible for breaking the barrier to many cultural taboos in Hong Kong during the conservative environment in the 1970s.

He is best remembered as the person who came up with the slogan "Two kids are good enough" for The Family Planning Association of Hong Kong.

Wong hosted several TV programs, mostly interviews or talk shows oriented towards adults, on both TVB and ATV.

One of the talk shows called "Off-guard Tonight" (今夜不設防), co-hosted by Wong and his close friends Chua Lam and Ni Kuang on ATV, is particularly remembered.

In the following days, the news of his death became the primary media headline in Hong Kong, and his compositions were played throughout the week.
