I come from China with an engineering bachelors degree. Currently live in southwest Chicago area(Bolingbrook,IL). I am fluent in speaking and writing in Mandarin Chinese. Proficient in math and science problem solving. I would like to teach people who are interested in learning Mandarin Chinese. I have 5 years experiences in teaching my 3 kids Mandarin Chinese at home. Now they can speak fluent Chinese, the biggest one who now is 6 years old can read and write 50 Chinese words.
