I purchased the Conversational Chinese 301 Vol.1 (3rd English Edition) textbook and workbook several weeks ago. These are great materials for self-study. I have found even without teacher guidance the lessons are easy to navigate and I am having great success retaining the information presented. The included DVD is of numerous scenes acting out the dialogues from each chapter of the textbook, and it gives a nice method by which to ensure your pronunciations of pinyin text are correct, as well as providing a resource to help "tune" your ear to listening to both native and second-language speakers. I don't often order from anywhere online but Amazon because I am always worried about the profesionality of an unknown company. Communication with Purple Culture was easy and professional when I had questions regarding my order. Shipping was prompt and the materials I ordered were packed well. For full disclosure, and to avoid sound like a praise robot, I was briefly worried when I received an order placed message, but never received a shipping confirmation or tracking number days later. This was no problem since I was provided this information as soon as I sent an email asking. Just FYI. All in all I am a highly satisfied customer who is happily making strides learning my second language. Thanks!
