Hi, you can look at this site and Learn to speak Chinese, Mandarin in Thailand ... Online Lessons: www.language-school-teachers.com/default.asp?selx6=12.

Watch out for what I call the NIHAO online schools. they are set up by people who just because they can speak standard chinese they THINK they can teach it. furthermore they charge u a HUGE amount of money. and at the end of it all you learn is NIHAO. I'm the firm believer you can learn a language on your own (with the right teaching material, books, and native speaker friends) however if you decided to go with an online chinese school ask as many questions as possible. find out if the teachers have a Chinese teaching degree, have experience, if they have a free trial give it a try. for the most part I think you can find many FREE online resources that will teach you chinese. have fun studying chinese.
