A square refers to a vast area, especially in a city. It is the hub of urban roads, a space for people to carry out political, economic, cultural and other social activities or traffic activities in the city, and usually a place where a large number of people and cars gather and distribute. Important buildings are generally arranged in or around the square, which can often reflect the artistic features and characteristics of the city. In the city, the number of squares is small, covering a small area, but its position and role are very important, which is one of the key points of urban planning and layout. The square is a place where people gather and rest, and it is also a place where people escape from the noise of the city.
