Minzu means nation in Chinese, and refers to the Chinese nation as the collection of five large ethnicities: the Han Chinese, the Man Chinese or Manchus, the Meng or Mongols, the Hui or Muslim Chinese, and Zang or Tibetan Chinese.
Minzu is a recognition of the multi-ethnic character of the Chinese nation, but it is also a nationalist concept that is used to suppress any attempt of secession.
Both Taiwan and Mainland China were founded under this principle.
