Southern China Commentary

Found this classified on a Guangzhou social networking website, and found it a little confusing.

What exactly is a Westerner?

Does it mean Physical Location?
Countries west of China? If we go west from China, and keep going at it, we’ll land in Japan some day, although all the while we headed west.

Does it mean Skin Colour?
But what about ABCs like Jay? He looks Chinese, is an ethnic Chinese currently residing in the land of ethnic Chinese, but holds American citizenship

Does it mean Nationality?
But my passport does not print for a matter of Nationality, whether I’m a easterner or westerner or South-Easterner.

So who really qualifies for this invite to free wine? I’ve heard of ladies drinking for free on Ladies’ Night. But Westerners? I’m confused!
