It opens with people pour tea and plan to get a book to overthrow the Qing dynasty. Wong Yu is gambling and works at the brothel where his mother is a hooker, yet none of that seems weird. There is a mix up with the aphrodisiac. Next his friend is about to be executed when a swordsman appears to save him. Some gag! Wong Yu takes the hero to hide at the brothel. Soon they flee to the capital but are captured by Ku Feng's gang. Wong Yu overdoses Ku Feng on his own medicine causing him blindness and takes the place of his servant.
This impossible sequence of events continues for the rest of the movie. Wong Yu is always in the right place at the right time. He is able to meet the emperor, played by Gordon Liu, to learn fantastic kung fu, and to reveal a usurper to the throne. All of this adds to his good fortune.
This movie has many weaknesses that are obvious and I won't get into. Technically the only good part was the pacing. It seems there is no way any of this can work. For me, somehow it did work. I liked it from start to finish. I rate it overall as a strong average for the year and genre but would not recommend it for anyone other than the most hardcore fan.
