I started my English learning thirteen years ago when I was a junior middle school student. Now I am a graduate student majoring in Enlish (specifically speaking, Linguistics).
I think the most effective way for language exchange is to listen and speak, so talking through mic is warmly welcomed.
It is really a great pleasure to meet friends who are interested in China and Chinese. I am not professional in chinese teaching. But as a Chinese, i am good at speaking it, hehe ^_^. I'll do my best to help you with your chinese learning.
And i do hope that you can tell me when my expression or pronouciation is out of fashion or not precise, even you can understand what i mean.
As for my Japanese, though i have passed Level 2 of JLPT, i am afriad that i am not good at listening and speaking. But i do hope to improve my skills in Japanese. If you are also learning Japanese and you can speak a little English or Chinese, and you'd like to share your learning experience, then i am looking forward to talking with you.
