Starting Out in Chinese is perfect if you want to learn while commuting, running errands, or at the gym - or if you want to learn at home and simply prefer an all-audio course. If you want to refer to written material, you can go online to download the audio script.
I have lived in China for 4 years now. I am well beyond what is presented here, but if you are planning a short trip this will give you the rudiments of the language. I endorse Living Language products and would recommend that you also download the PDF and follow along to further speed your progress. Both Living Language and Pimsleur products have made me conversant in Chinese. Now I am working hard at reading and writing.
