About the ID number you hav eto key in one to create your account;;; should ask to a chinese friend, other way not sure at 100% is to find one througth internet > search on google and you'll find this web site http://www.sinosplice.com/life/archives/2005/04/19/chinese-id-cards ) there is many others :p but think it could be dangerous... I did like this, I openend my 1st wow account with this, and now I really fear to lost all a day... So ask to a friend is the best way.
