I have just read the postings about Mr. Duke from this site...
I don`t spy on others ! I have also the right to express my opinion about Frank Zhang.
I prefer the truth of those ones with good manners. ( Yingwen Laoshi, Robert Lokyer... and few others ). Mr. Duke will not get anywhere with his lack of common sense ! ( the same for you, Turnoi ).
Don`t come here with childish, dirty games ! ( about the bad English of others, spying on others... and so on ! How many of those ones with bad manners have got a job from Frank Zhang ? Not even one !
