Hi Sharon,
This is Li Xia. I learned from your post that you want to improve your Mandarin. I feel honored to have the chance to help you with your Mandarin learning and I am very happy to have you as my English teacher. I'm good at speaking standard Mandarin. I've been a broadcaster in the school’s broadcasting station for years. When it comes to how to speak fluent Mandarin, I suggest that you learn a bunch of pronunciation rules first, which are quite different from the English ones. Another suggestion is to practice speaking. As the saying goes, “Practice makes perfect”. However, my English is just OK and I have many problems with my study. I really hope that you can give me good advice on how to study English well. I believe we both can make much progress with each others’ help.
Thank you!
Li Xia
