When I saw the phrase "jointly discussing national affairs", I thought that I was not fulfilling my responsibilities and made a typo, and I only had "jointly discussed national affairs" in my cognition. In fact, the meaning of "discussing the country" and "discussing national affairs" is different, and "the country is" refers to the country's major plans, which are major decisions such as national policies and guidelines, and are mostly used in written language, and the context is solemn and serious. "State affairs" refers to the affairs of the State and is a more specific designation. Therefore, the "is" in "the country of common consultation" cannot be replaced by "matter".
There are four differences between state affairs and countries
1) The scope of the meaning of the word is different, "state affairs" can refer to both matters that have a significant impact on the country and general state affairs; The "national is" refers specifically to major affairs such as national decision-making and planning.
2) "State affairs" can be used both domestically and internationally, for example, "state visit" is an official visit made by a head of state at the invitation of another country; The national events referred to by "national is" are strictly limited to the national affairs discussed by the Chinese people.
3) The stylistic colors are different, "Guoshi" is a colloquial word, and "Guoshi" is a literary word used in written language.
4) The grammatical function is different, as a noun, both can be used as the subject and object, but "state affairs" can also be used as a definite sentence, such as "state visits"; And "the state is" has no such usage.
