After 1949, when the CCP took over China, they wanted to "liberate" all minorities from their lords and Han majority. They created 55 minorities + Han. Before 1949, only 4 (Manchu, Tibetan, Mongolian and Hui) + Han were officially recognized. They wanted to apparently divide China into smaller pieces, which was understandable since the CCP even established their Soviet little country based in Yan'an before 1949.
After they created 55 minorities,
1, The CCP also helped create written languages for certain minorities, such as Zhuang, Jinpo, etc.
2, The CCP created so called "autonomous regions," from provincial levels to county, village levels.
2, The CCP changed all Chinese names where ethnic minorities inhabit to minority names, for example, Dihua to Urumuqi. Taiwan still calls Urumuqi Dihua
3, The CCP imposes one child policy on Han but not on minorities.
4, The CCP abolished Han's folklore practices, forcing Han majority to cremate but allow minorities to have tombs, in the spirit of protecting minority cultures, as if Han has no culture. Recently, in Henan, the CCP even destroyed Han majority's ancestral tombs.
5. etc, etc...
Meanwhile, what we got since the CCP implemented those policies? More ethnic violence and division and the world media is even criticizing the CCP for "oppressing" minorities? I am laughing at the incompetent and ideology-driven stupid CCP.
As they antagonize the Han majority more and more while the minorities feel more and more empowered, I expect more violence. The CCP might be digging its own grave and I fear when democracy comes to China, the damage is too devastating for the nation to heal. China might break up if China goes democratic.
