Just visited your blog, Baining! I think it's great! It gave me a lot of tips and ideas on how to keep my daughter interested in learning Mandarin. Granted, she's only 18 months old so I will have to save your tips for when she's older. But we live in an English-dominant environment (she goes to daycare while I work), and although I have the advantage of being able to speak Mandarin to her while she's at home, I need all the help I can get to keep her interested in learning to speak, read, and write Chinese. Thanks for sharing!
