My maid is 100% 鄉下婆 from Indonesia. Never worked aboard before. It took me REALLY very long time and patience to teach her. If you do not have sufficient time, do not hire inexperienced Indo. My maid is stupid, slow learner, no common sense and we basically couldn't communicate with her: NO English, nor Cantonese.
But we found that it is good, we 捉住手教, don't expect she understands by 1 time or 2 times. You may expect 5-10 times, then they get it. 未到過hk既maid are JUST VERY stupid.
