Interesting thread
Query: How long into the past can we say that Cantonese has existed as a language? That is to say, how early can our POD be? (Probably later then the origin of written Chinese, I’d assume.)
To disrupt Cantonese cultural unity with the rest of China surly what must be done is to make the written form of the language as distinct as the spoken- is there any feasible way to do this?
(Though, the idea of a Western Power attempting to clam the Dragon throne is interesting, if implausible. Much more divided China? Maybe earlier POD, with competing Mongolian, Tibetan, Manchurian, and Native Dynasties in the North and Center, with large European colony in the south? )
