You can't bring fresh fruits and vegetables into Mainland China. They'll pick them up on xray, confiscate and weigh them, take your passport, scan it, and give you a receipt for so many kilos of apples or whatever. You'll then be in the system, so don't do it again.
Good point; I honestly didn't know the rules.
For girls, I'm thinking Michael Kors purses. They are really cheap in the US, and are more unique than LV.
I need to think more about young men.
