Chinese interface on android?

[mort3987]

After recently getting my parents to switch to android from a simple flip phone, they're now asking how they can change the interface of their phone to chinese. I've tried looking around everywhere and I've figured out how to let them input chinese characters, but I can't figure out how to change their interface to chinese. Does anyone have any suggestions? Btw they're using an epic 4g on android 2.1. Thank you in advance.
