I am embarrassed to say I do not remember a lot of Hanyu that Mai Laoshi taught me (dui bu qi), but it was a pleasure studying a year of Chinese as well as a term of writing systems – I remember vividly studying how to read Korean in the library right before the final exam. I recall very fondly drinking a beer with him at our 5-yr reunion and Mai Laoshi being the cool prof who participated in the Carleton triathlon.
Omedeto and Gongxi Mai Laoshi!
