Hi everyone! I'm Chun from China and living in the US now. I've been studying English for more than 20 years as a student in schools. But my oral English is a little bad because we usually don't have much changes to speak English in my hometown. But now I came to USA for some research works. So, I need to improve my oral English now. If you are learning Mandarin, want to improve and practice it. Then I think we can help each other. Thanks a lot!
