The state is a political entity surrounded by borders and a region where the state power exercises power, which can be regarded as a political division. However, the political division surrounded by such borders is only a form of the state, not the essence of the state. The state means that the people within the border have formed a kind of "cohesion". This cohesion can be called "national consciousness", that is, everyone thinks that I am a "national". A country, which cannot be called a country, in essence, is very unstable. The real big country is not only a large territory but a large population. The key is whether its nationals have developed a "national awareness" and produced a "national identity. ". This passage mainly talks about:. ['National border awareness.', 'The nature of the country.', 'The role of national identity.', 'Connotation of national consciousness.']
