Nation-state is the major form of human society in the modern age, it emphasizes that the state is formatted by a nation. However, national integration and national formation do not come to in the same process. The nationalism, precisely defined, ethnic(aboriginal)nationalism, represented in Republic of China has provided the best example for the evolution of cultural nationalism or ethnic nationalism in human interaction and historical memory, and it has formed an imagined community or identity. Contrarily, though the minor nations have been privileged and have their own autonomy on Mainland China, the huge geographical space and inconvenient transportation hinder its national integration and formation.
