Could Yue/Baiyue people have maintained themselves in southern China (it doesn't have to be all of it), either on the form of one state or several, or as a constituent people of one big chinese state (as Hui)?
I understand the big problem was their lack of cultural (while, from what I gathered, they were related to modern Viets) and political unity, but how could have been made?
Furthermore, what would be (in the great lines, I don't expect a TL or either precise indications past the first centuries) the consequences for Far-East and maybe more global history?
