Hi! Happy to hear that you are interested in Chinese. But I'm on my business trip.. in Beijing. Since I didn't carry my laptop computer, it is hard to give you my reply right now. I'll give you my answer to you when I go back to Korea. I think, I can get back to you tommorow or next Monday. I would like to share my idea about learning Chinese with you all. Have a great weekend with your lovely babies. Bye..
