A friend of mine is looking for a kung fu film he saw a long time ago: "I am looking for the name of a kung fu movie I saw 20 years ago. It is about a construction worker who builds scafolds. One day he is working out side of a kung fu school. Inspiered he begins to learn kung fu. The hook in the film is that he incorperates his scafolding building in his kung fu. I don't remember any thing else about it." Thanks.
