The Lady is the Boss (1983)

Synopsis

Wong Hsia Yuan is an old-fashioned martial arts master who's so behind the times that he'd rather his school be destroyed than change its ways. He may get his wish, thanks to the young, beautiful, intelligent Chan Mei Ling, who arrives from the states to open a new branch of the school. Armed with an unfamiliar, modern way of thinking, Mei Ling goes about recruiting new students in strange, and sometimes questionably legal ways. Yuan is furious, but when the local triads enter the picture, the two put their differences aside to take back the neighborhood.
