yunnan,guilin is a trip i always want to make. i crossed one post about olympics the other day and read your replies about china, very impressed, and so gald to see some peole could give rational and real view about the old nation. im originally from beijing, havnt back home a while tho. maybe like people said, only when you are traveling that place, you will have the interest to explore that place, im quite regret i havnt done much traveling when i was there, even didnt go to great wall!!! few friends back home recently and told me how much changes going on there, i cant wait my home visit :))
regarding your question, i reckon you checking nationwide, thats the only bank i heard wont charge you for using card abroad, also i suggestion exchange your money over there, as rate is better than here. hope you enjoy the trip.
