exclusive is the common view that some country people defined. but, you cant draw the conclusion if you dont live with them.
so you should seek a shanghai girlfriend. and then, tell me you real feeling!
one of my unversity dorm mates come from shanghai,
lol,he is really exclusive,in his view,we(without shanghai citizen ship) are country man,
he think he is the most noble people of china,
for girl,I can juge from his girlfriend,
you know shanghainese are pretty shrewd ,so they will pretend to flatter you and give you their trick under the table!
