And just during this period, my personal experience made me realized that there're really good guys and also there're really bad guys EVEN among the Foreigners (I hope my point's not that unbelievable, coz you yourself also always say that: you were also come here in the world with your original sin :) And before making refutation, I suggest you have a look in your jail firstly, and you do have jails in your country, don't you??? :) It's a place where your goverment put the BAD GUYS behind bars :) Or you also can look back into your history, and find out what your ancestors ever did to the local Indians when they put their first step on the American soil, and right after there's a THANKSGIVING ?!! And how originally the BLACK PEOPLE came to American? So can you deny my point which is " there are also the good and the bad among Foreign Guys" ? And then what makes you so sure that it's absolutely impossible that there are "BAD FOREIGN TEACHERS" here in China among your circle!!?
