This and Ban jin ba liang both made by Hui brothers really brought in new approach to Hong Kong cinema. Hong Kong was fortunate in that it had fertile ground for movie making because of early efforts by the Shaw Brothers, and later the Golden Harvest. Golden Harvest's contribution in modernizing Hong Kong cinema can't be overlooked, but as independents, Hui brothers did almost as much in changing the direction of Hong Kong cinema.

Interesting plot combined with comedy, set in modern Hong Kong that didn't involve love romance was a fresh new approach for Hong Kong cinema of its day. If we look at the proliferation of this type of movies in the '80s in Hong Kong, it's clear that Hui brothers were way ahead of the game.

Sam Hui also wrote the music for this movie. His talent is indisputable, as is his contribution to the Hong Kong's pop culture.

This is one of the seminal movie of its kind, and is recommended for viewing by all Asian movie fans.
