If I arrive at PEK and apply for the 72 hour visa, does ihe 72 hours start at the beginning of that day of when the visa is issued or the time I land ? Example: If I arrive at 2:00 PM on a Monday is it valid until 2:00 PM on Thursday or midnight on Wednesday? Does your next flight have to be scheduled departure before the expiration time or do you just have to check in and be through Immigration?

Thank you
