Hello,
Will be traveling through Shanghai-Pudong airport next month. My stay is 36 hours total. According to the China embassy, stays of less than 48 hours through Pudong airport are Visa-free, provided passenger can show proof of onward travel and is a resident of certain countries, such as the U.S.

Considering a Chinese Visa runs well over $100, this ability to stay Visa-free is a real bonus.

Anyone have any experience showing up in China without a Visa under the visa-free travel rule? I was going to print out the documentation from the embassy website for "proof" but realize policies could change at any time...
