Do the families have curfews?
While most families will not directly set a curfew, it is considered polite to agree on an average time you will be home on a given night, so as not to disrupt their work and study schedules. However, you will find that most families are very open to western lifestyles and tend to let you have your privacy. Just don't bring back a crew of late night party animals at 4am on a Wednesday night and you should be fine. 

Are Chinese people nice to foreigners?
For those of you who have been to China and are reading this response, I'm sure there is a bit of a chuckle involved. Chinese people are almost too nice to foreigners. Get ready to have your picture taken by curious bystanders and be prepared for people to offer you free rides everywhere. Chinese people strangely intrigued by foreigners and tend to stare and giggle quite a bit. If you speak Chinese, be prepared for some big smiling Chinese faces.
 
How do I get a phone that will work in China?    
If you wish to use your current phone in China, make sure to contact your local phone company before you leave to get the necessary access codes that will allow your tri-ban phone to accept other SIM cards. If you do so, your phone will work with the SIM card IHC provides you right when you get off the plane! Otherwise, IHC will personally take you to find a phone within your first week.

Do I have to register with the local police? 
If foreigners plan to stay at a residence in China, the law requires them to register with the police within 48-hours of arrival to said residence. IHC will take care of this for you upon arrival.
