I'll teach you Mandarin, you can teach me English(live)

Hi, I am Chinese and very fluent in Mandarin, and want to develop my English speaking ability. If you teach me English, I will teach you Mandarin. It would be better if you are English native speaker.

If you speak English, please give me an email. Send emails to: [...] . I live in West London, so ideally you won't be too far from me.
