Let's skip over the question of why anyone would want to bring wine from China!

I recently returned from Shanghai, on American, and was amused to see the sign at check-in (would have taken a photograph, but not a good idea to pull out a camera in an airport these days).

"No wine or knives allowed in cabin"

Obviously it's the wine drinking air travellers who are the dangerous ones. However, there's no restriction (other than weight) for packing wine in the checked baggage (I often travel with styrofoam cases for that purpose - but didn't take them to China).

Where there's a wine will, there's a way.
