Ah I see, yes indeed it is hard. By the way, I just discovered that Miss Liu's roster of "good teachers" is on her part a motivational ploy. Those people who toe the part line, so to speak, and don't make waves get put on her website, and are touted as "the good teachers". Truly sickening lady really, I would like nothing better then to put her out of business. I don't understand how, after all this time, she is still in business.
