What you are doing right and the others aren't is two fold.

First of all, you have a progressive series. A person can actually start from the beginning and work their way up to a conversational level. All the words are accounted for. You remind people of what is new and what has been covered already. You remind them in Chinese and use English sparingly.

This is the way that it should be done. After the initial stages, a language should be taught in the target language as much as possible.

The second thing – Lessons are introduced in Chinese.

I think your service is actually quite good. I wish that I had this service when I was younger. I'm serious about improving my spoken Mandarin, so I subscribed to you site. I actually like yours because the lessons are short and concise (6-8 minutes) and Kirin and Rafael speak in Mandarin only. I also like your videos.

As an American Born Chinese (ABC) and native English speaker, I feel that Chinese Learn Online is really the BEST Mandarin Chinese learning websites! I studied Mandarin at UCLA for one summer and the National Chengchi University (NCCU) in Taipei, Taiwan for 3 semesters.
