I bought this book + CDs after I finished another Cantonese text for beginners. If you already have some knowledge on Cantonese, this book really helps you learning more words and colloquial expressions.One thing I don't like about this book is that all the Cantonese sentences are written only in alphabet. If you already know Chinese characters, it is much easier to remember words and expressions if written in Chinese characters.
