I am learning two languages at a time: English in language school, and Mandarin on Tutorfair. Kali is recommended by a couple in Simmons Bar, the couple told me their 8 years old son and 11 years old daughter learned simplified Chinese every weekend, and they could talk a lot, as well as reading. I wrote down the name and website, finally found this young tutor. He looks like 16 years old (in fact a PhD), a funny guy, with a casual style. The first 3 weeks, everything is totally too easy for me. We changed the plan twice and finally fitted me. What a detailed plan! Kali is good at handwriting I guess, as he could write Chinese and looks quite nice. His lessons are mostly a casual style, good for communication. However, he could make it better in his next lesson.
