I noticed this the first time I came to China, but my last trip was the first time I've had the opportunity to take a picture of it ... beer in vending machines.

This is something that would be unheard of in the US, mostly due to the drinking age and regulations surrounding the buying and selling of alcohol. I wanted to buy one and see just how fresh it was, but I had already loaded up on the 11 hour flight in (not to mention the 3+ hour delay before the flight), I was dead tired, and CNY 10.0 is pretty expensive for Chinese beer (unless buying from a bar), so I just took a picture instead.
