Welcome to the Forum diginode
Question very confusing. can u frame it properly.
letz see...do u mean that u got a WinXP-SP2 bootable CD and its chinese version. and u want it to be working as ENG version.
If that is your question, u cannot do that. Get a copy of English Version.
PS: I'm taking for granted that you have a GENUINE copy of that. If not, sorry ur in a wrong place.
