That's the problem with a lot of these places. Ask the world from the foreign teachers, yet leave them in the dark about many things. I can't count the number of times classes were cancelled or rescheduled without telling me prior. Or special events popping up without letting me know first. This shit gets old really quickly. And no, the schools DONT learn, which is sad.
It's good we have Hefei Expat to keep them "somewhat" honest.
