Those maps are insane. They are making up a bunch of shit states out of nowhere on places that are like 99,9% han. Imagine being this nerd to take the time to carefully make up all that bullshit that maybe no one in China actually knows of.
The only ones making sense are Uyghuristan, Tibet, Manchuria, Inner Mongolia, Taiwan, Hong Kong, Macau and maybe that state for the Muslim Han (I forgot the name of that group) and maybe Cantonia is not a bad idea too. The rest are pure madness and made up nonsense.
