One question for example, is: -- When the empire formerly known as Sung was governed by the Mongols, was it in fact "China"? Similarly, the last great dynasty, the Ming, was of course run by the Manchus, so in what sense was it "Chinese"? Similarly, when the "Japanese", to be polite, plundered and raped "Taiwan" and "Manchukuo", was that turf still "Chinese"? Lots of nitpicking, I know, but people spend their lives on this stuff.
