We live in a sin cursed world and there is always good and bad no matter where you go in this world .
If your going to China to truly teach so you can expand and improve on the quality of some ones life , someone who has a different world, reality and totally different set of values than the west, then go with that goodness in your heart and do not expect to find anything .
Go with the intent of giving and learning too, from what the experience in that reality and life offers you.
Be aware that esl is a money making business in China and many opportunist are in the market place to make money and even deceive and lie about jobs and what is offered . I advise you to check with another teacher by phone who has worked at that school . Ask them there personal experience. But don't expect to find what you find in the west. Lieing is a way of life in China and they do it well to survive.This is just natural to them after years of being abused and ruled under a totalitarian government.
Have money enough to leave any unpleasant encounter , especially if what you contracted for is not true. You are free to just leave on any train, plane , boat or buss at will. Nothing is holding you, no matter what anyone says or tries to threaten you with.
Go with a good clean mind and heart, give without the intention of receiving anything other than a new life experience and some basis money and shelter in return,
Don't expect to find any spirituality or religiousness going on in China. Its just not there .
You have manya rticles to read on Daves. Many are written from prejudice and high expectations from spoiled individuals who never had to live under such depravation and lack of values and opportunities.
Be well, don't get caught up in the bars , girls and evils of life when you go there. It will not give you anything of gain and surly lead you into the same pit those you find others in .
Live a quiet simple life and just do your job well. Give respect and do not try to think or act that you are any better than anyone else. You will die and rott in the same grave as anyone else, leaving this world with absolutely nothing ; the same way you came in --with nothing--naked!
If your out to make money them don't go to China. Don't work more than 20 classes a week or you will find yourself ladened with stress , regrets and sorrow.
Be well---
From a teacher who saw, did and lived in China for many years.
