Graduated from Peking University, China (best university in China). I have a solid background in math and statistics with a master degree in public health and bachelor degrees in public health and economics. My first language is Mandarin and I would be very glad to teach anybody who wants to learn it. I taught Mandarin through Italki before, excellent on teaching speaking and writing.
I will be truly pleased if I can offer you some help.
