Speak Cantonese, Book Three, is one of a series of books that teaches the modern spoken language of Cantonese, one of the major dialects of Chinese.  As appropriate for a text of its kind, it is entirely in romaniation.  This volume is the last of the Speak Cantonese series.  It emphasizes introducing more idiomatic expressions heard in daily-life situations- a chat in a teahouse, an argument on a bus, a skit broadcast on the radio, etc.
