The problem is not Delter. It is China. Ever since they got their WTO membership and Olympic games in 2008, China has become meaner. I was at Delter in 2002, 2004, 2005. I went there between university assignments. I went there in 2008 and Delter was mean by then. But all of China has become meaner, compared to 8 or so years ago. You need to especially talk to those British teachers and Americans who can compare it to something, like how it was 10 years ago. The Chinese staff at different places have become more arrogant at the universities. Someone told me this long ago: "Mainland Chinese are always polite but they are not always nice." They will stab you with a smile on their face, including after they have stabbed a friend or anyone. Do you know that Chinese children are whipped and hit with hands, whenever they do not smile? That is a fact . That is why often the Chinese are hard to read. I came for the women, sight seeing and I am a good teacher. Your students are the best part here. And there are plenty of women here away from the place you work at. Be a good American, British person, Candian, Austalian, New Zealander or any other person. Do what is right because it is the right thing to do. Have a good time but do what is right. While you are here but always remember, the Chinese are getting the better end of any deal you make. I was told that by a guy who was first in Taiwan for years and then in Mainland China, after 1979, when he was able to be there. It is just my advice.
