The theoretical reflection of Corbusier's praise for machines is "machine aesthetics". Machine aesthetics pursues simplicity, order and geometric form in machine modeling, as well as rationality and logic embodied in the machine itself, thus producing a standardized, pure and pure model. Its visual expression is generally based on simple cubes and their changes, emphasizing straight lines, space, proportion, volume and other elements, and abandoning all additional decorations. Before the machine aesthetics is actually applied to the machine itself, it is first embodied in architecture and some practical works of art. The interest in the machine here is rather the interest in simple and abstract forms. One of the most influential and criticized words of Corbusier is that "housing is a living machine". He advocated using the rational spirit of machines to create a "living machine" that meets the practical requirements of human beings and has perfect functions, and vigorously advocated an industrialized building system. Some of his architectural designs adopt the shape of machines, such as imitating parts of ships and airplanes, but they have nothing to do with the function and efficiency of machines. These designs push machine aesthetics to the peak.
