Thank you for viewing. I purchased this at a bookstore in Hong Kong some time ago as a Cantonese language textbook. It includes Japanese explanations and I think it's a useful textbook for those with a basic knowledge of Cantonese. I bought two copies, so this one is unused. It also comes with a CD, which is unopened. As it has been stored at home for a long time, although it is unused, there may be some sun damage or minor wear and tear. Also, since language is a living thing, there may be new versions of the book with updated phrasing, but I think this is a textbook that is difficult to obtain in Japan, so I am offering it for sale. I hope that those who understand the above will find it useful. Thank you very much.
