Actually the palest issue is quite similar to china.
Cuz try imagine using china 3 kingdom time. 吴国 control 3 州 mainly 杨州 荆州 交州。
sometimes later 吴国 for easy managing also craft out to have 广州 which is part of 交州. Create 广州 and merge back to 交州 and recreate 广州 again.
Simply put it mean you can say there are 广州人 who happen to live in 广州 area but they are supposedly be also 交洲人. But 广州 also covered let say modern 广东省 福建省 etc so are those people or migrants living there supposed to be call 广东人 or 福建人?or广州人?or交州人?or吴国人?
If want trace back to before han dynasty. They are all under maybe 楚国 越国maybe。
So the question come liao say 福建人 should be owner of their so call 福建省?广东人 should be owner of 广东省?but in the first place they have a kingdom? Have emperor or king name 广东王?福建王?
But then living in those areas lands also have 客家人 leh. So maybe 客家人 also should declare independent establish a state 客家王?
You get it? Cuz palest is never a kingdom cuz they got no king while on map or books there are mention of Palest people or land but it's not a firm definition they own the land cuz within that land have many tribes and many other names.
The place or land was ruled by many kingdoms that's not call palest kingdom at all.
In the first place, a country will exist only when you 列土封侯王。占地为王。if there is no king its very difficult to say oh the land belong to these people cuz people keep moving migrating
If 荆州 never go back to 吴国。does it mean 荆州 people should call themselves 汉国人?or 蜀国人?
