Camino? Sitter mainly discusses the principles of urban space and art organization from the perspectives of vision and people's feelings about urban space. Camino? Sitter believes that the pride of modern urban planning is the circular square, and nothing can better explain the complete lack of artistic feeling and contempt for tradition, which are the characteristics of modern urban planning. Walking around such a square, the scene in front of you remains unchanged, making it impossible for people to know their correct and exact position. Turning a corner is enough to make a stranger feel at a loss and lose his way in this carousel square.
