Service is really inexpensive in China.
You can certainly enjoy that the most. Family, food, and convenience, those are all very unique.
As for apparels, I really don't think there is anything worth buying in China. Cheap ones are cheap for a reason. Good ones are normally regular price in US times 10 or 11, why bother?
As for the photos, isn't it really scary if everyone is pretending to be 18, 19?
