This system plays Chinese audio, followed by Japanese audio. Furthermore, using the textbook as a supplement will deepen your understanding. The package says 2003, so I believe it's from around that time. Product Condition: CDs for Volume 4 are missing. The textbook is included. The CD case for Volume 5 says "Old Item," but there's no problem with the contents, and it's not particularly significant. The textbook has hardly been used, so it's in good condition. As a bonus, I'm including a CD player. It hasn't been used much, so it's in good condition. Overall, it's in good condition, but it is a used item, so please understand that before considering a purchase.
