<A>The only time I had any issues of anyone attempting to take advantage of me because I was a traveler was in Guangzhou. In a film shop by the White Swan hotel, I went in to purchase a couple of trinkets that our son had shown an interest in. When I went to pay for them I should have gotten 5 Yuan back but instead got the lower 5 denomonation. I looked at the shop keeper with my hand still extended and the change that she had given me and simply stated boo (no). She looked surprized and immediatedly apologized and gave me the correct change of 5 Yuan. Get to know the currency! Also only exchange your currency at your hotel or bank of China.
