Hello, I'm Jack, I am a native Mandarin speaker! I live in YunNan(云南）province, China.My 12-year-old son and I study English for several years by reading. And we have little chance to speak. I want to improve my spoken English. 如果你在学中文中遇到任何问题，都可以来问我！I am patient! If you have any questions about learning Mandarin, contact me! I use skype and WeChat! Look forward your messages!
