The square is a simple and direct shape that symbolizes stability and steadfastness. In construction, the use of square structures can increase the stability of a building, thereby creating a longer-lasting building. Square ideas can also be used in designing unstable systems, making decisions about complex problems, and building reliable machines. Therefore, the square shape is equated with stability and trust, expressing a firm belief in something.

In addition to stability and faith, the square is also considered a symbol of security, conservatism, tradition and order. In today's world, many people have begun to pursue simplicity and functionality, that is, using straight lines and neat geometric shapes to convey a message of simplicity and grandeur. For example, many modern airlines use the square shape as their trademark to convey a message of simplicity, reliability and safety. Therefore, the square is seen as a simple, stable and pleasant form, which brings people a sense of security and stability.

In the field of art, the square is an unconstrained open-minded and creative form. In contemporary art, many artists use square shapes to convey a new sense of collaboration and a perspective on the ever-changing and innovative digital age. For example, the work of Dutch artist Peter Strecks explores the geometry and infinite possibilities of the square. Therefore, the square can also express unlimited creativity and outlook. As an architectural cultural heritage, it has also made great contributions to the development of modern culture and law.
