I have been in taiwan for about 7 months but currently i haven’t formally attended any chinese class/lessons and am seeking a private teacher due to the fact that my job requires me to work 6 days per week (finish work at 10pm) leaving me no option according to what i found to go to regular classes, my question is is there a bulletin board with mandarin teachers in taipei where i can search for a qualified teacher, if not where should i look for one?
