I purchased this a year ago, but I don't think I'll have the opportunity to study it, so I'm putting it up for sale. I'm selling it. This is an introductory book that teaches conversation and grammar in one volume. It's supported by a CD and an app. - Title: New Express + Chinese - Author: Sachiko Aotayama - Accessories: CD - ISBN: 978-4-560-98773-1 - Price: 2000 yen (excluding tax) Thank you for looking.
