Community refers to a large residential area with a relatively independent living environment in a certain area of the city, and is equipped with a complete set of living service facilities, such as commercial outlets, schools (kindergartens), etc. Urban residential communities (neighbourhoods) and residential communities are generally referred to as communities, which refer to residential areas, garden houses, and residential groups that are mainly residential and equipped with corresponding public facilities and non-residential houses. The main characteristics of communities are: diversity of residential forms, unified planning, diversity of community functions, diversity of housing property rights, and modern sociality of communities.
