My situation is at follows:
I plan to visit Beijing for 3 days, then go to Japan and then go back to Europe. The thing is, on my trip from Japan back to Europe, I have to do a transfer in Beijing again.
I just want to be sure this won't be a problem. I'm asking because I read that when using the 72 hours visa, you cannot use it to go from Beijing to a place outside China and then back to China...
