Karkies, I used to live in China (Beijing and Dalian to be specific) and as much as I enjoyed my experiences, I have to say travelling for business in China is a far different (and comfortable) proposition. Things just get done more quickly and efficiently (save for traffic). Your hotel can take care of almost everything (giving you restaurant and cuisine suggestions, business cards to help you get back to your hotel, addresses writtin in Chinese etc).

Never be worried.

1. Learn some Chinese phrases (hello, thank you, good bye).
2. Don't be afraid to look dumb. If you are not being understood (very few people speak English well), feel free to play charades. The Chinese are patient and play along. No I am not joking. A certain story regarding purchasing hand sanitizer a few years back before I could speak Mandarin comes to mind (PM for details).
3. Be sure to call your bank and CC companies and tell them you'll be in China.
4. PM Jamoldo if you want Chinese food/menu translations (warning: its very exhaustive and you probably don't need it, though I can personally give you a few characters to look out for if you have specific dietary needs/desires).
