I've just come back from the most amazing trip to China....would recommend it to anyone....it's very full on (early starts) but every minute is wonderful :)
But here is one tip I've picked up that I think is worth passing on: If you're planning to change sterling into Yuan over there, which is very easy and very cost effective (higher rate of exchange over there) make sure you take notes in perfect condition. If there is even a tiny tear some places refuse to change it. So freshly printed notes are a safe bet!
And enjoy...............as my lot could tell you, I did and took over 2000 photos to prove it!
