The answer is, yes, Vector Linux can support Chinese. Since I neither read nor write the language I don't know the details. What I can tell you is that if you open gslapt and search on font you will find a number of Chinese font packages. You will also need to install scim. I know we have HOW-TOs for Japanese and Korean and I imagine some of the same software applies. Check the HOW-TO section of the forum.
Are you looking to localize your system, where the menus, help, etc... will be in Chinese as well? I can give you some links if so.
I'm sorry I can't be more specific. I agree that is a separate topic. Please also mark this topic as [SOLVED]
