there are many many ethnic minorities. but the overwhelming number are han chinese. there are minority enclaves all over, all fairly unimportant and marginalized by the govt. that said, the answer i gave earlier is correct, taiwanese are ethnically the same as mainlanders, with a smattering of more japanese. tainwan is mostly han chinese from the mainland that are refugees of communism. chinese, like us, and india, and a other places, see a divide between north and south, where southerners are louder and more less sophisticated and party, while northerners are quieter, more educated and urbane. i guess this is true of lots of counries, reversed for england where the southeast is classy and the northerners and west country are hicks.
