If you are a digital photo person take some care when getting them transferred to CD in some places. Beijing we had no problem but one little outlet in the South infected my card with a nasty virus and as a result I lost 110 of my 145 photos on the card. Photos are precious so it is better to Take lots of cards and keep the transfer for home if you don't want to get caught like I did. Unfortunately for me it was at the end of our trip and there was no going back to replace the lost photos!!
On top of that my card was no longer usable and I had to throw it away!! Still a good reason to go back to China to get the ones I lost!! Looking forward to the return trip.
