Cities, also called urban agglomerations, are larger settlements formed by the agglomeration of non-agricultural industries and non-agricultural population. More densely populated areas are called cities, which generally include residential, industrial, and commercial areas and have administrative functions. The jurisdictional functions of a city may cover a wider area than itself, including residential areas, streets, hospitals, schools, offices, commercial outlets, plazas, parks, and other public **** facilities.

City (chéngshì) is a combination of the words "city" and "municipality". A "city" is an area enclosed by a wall, etc., mainly for the purpose of defense. The Guanzi (管子)-Du Di (度地), says, "The inner city is the city, and the inner city is the broad city". The "city" is a place for trading, "the city in the middle of the day". These two are the most primitive form of the city, strictly speaking, are not the real sense of the city. A region as a city must have a qualitative normative.
