1.Be humble. People here will spend their hard earned money (at times) to make sure that I have a comfortable life here, which leads into #2.
2.Share. Sharing is not taught to us in America, at least not as much as it should be. People share all the time here, and it really makes you feel better when you do share.
3.Look both ways. Walking across the streets in China can be dangerous, especially for someone from the west. However, for a country that has less restrictions of driving, I must say that the Chinese are the best drivers in the world.
4.Treat the culture, the people and the country with respect. Yes, there are things I don't like about China, but the good far outweighs the bad, and I see myself living and working in China for many years to come. China is a great place to work and live, and a hell of a lot safer and nicer than America, in my opinion. You don't want someone coming to your country and disrespecting it……(however, with my experience in America, you can talk as much s**t about that country as you want. I do it all the time. Just watch out for the super patriotic junkies.) 我爱中国！
5.Save your money and watch your spending. The food, clothing (if you can fit) and the life in China is so much cheaper and (depending on how rich you were in the west) is a great place to live and work. That being said, you lose a sense of money here and you have to make a budget for yourself. You still want to travel and have fun, but just be careful.
