In China, there is a group of people in a certain province, called Hak-Ka, translating somewhat to mean "Outsiders". There are Hak-Ka restaurants in San Francisco that serve Hak-Ka food - that to me, doesn't seem to be much different than standard fare, except for really tiny tea cups.
They had been in that province for 700 YEARS!...and are still called "Outsiders". Maybe they had an Affirmative Action program for them when they got there, and earned everybody's resentment for ever afterwards..who knows?
