i want to find a partner to practise language in a certain time.

you can speak English too 

I can speak both English and Chinese equally well. Take your pick.

Are you looking for a teacher, or just someone to chat with?   I have recently returned to US from China, where I taught university-level Oral English, and I am now accepting new, online students.

If you only want to be a free language partner with other students, that’s ok.  When you want some professional help, let me know.
