A set of three books for Chinese Proficiency Test preparation! Individual sales are also available. ① Leftmost: Kiku-tan Introductory Edition (Grade Pre-4) A vocabulary book. Audio can be downloaded online! However, I have lost the accompanying CD. There are a few scratches. ② Middle: Kiku-tan Elementary Edition (Grade 4) A vocabulary book. It's in good condition. It also has the CD. ③ Rightmost: Complete Mastery! Intermediate Chinese Proficiency Test Grade 4 It's like a textbook. I switched to HSK, so I haven't used these much at all~ There are no markings.
