Hey, i dont normally post in here but was browsing so just thought i'd add my 10 cents worth!
the Ace is back - i know what you mean, I spent 2 1/2 months in china and tibet (what a screwed up place!) china is a very strange but quite a unique experience, one village we went to had only been open for a short while and it resembeld an african village and the only place where i actually saw more human crap outside the long drop than in it, someone must have forgotten to explain the concept when they built it. whereas the big cities are quite western, minus the spiting, queue jumping etc etc!
places to visit, Xian the warriors are awesome, Chendgu and hop into Tibet, its dirt cheap, easy and once they build the rail link in it will never be the same again. Take lots of patience with you, you'll need it!
Price wise I spent roughly the same in 2 1/2 months incl China Tibet and Mongolia that I did for one 1/2 months in OZ.
