A reverse movement from within modernism is a rebellion against the pure reason of modernism. People are tired of facing the cold and inflexible design all day, which expresses people's desire for humanized and humanized products. Modernism and postmodernism are two extremes in style, but they have similarities and differences in many aspects. For example, Hassan made the following comparison between these two parts in The Turn of Postmodernism:

Philosophically, modernism is based on rationalism and realism, while postmodernism is based on romanticism and individualism.

Ideologically, modernism emphasizes the worship of technology and the rationality and logic of function, while postmodernism advocates high technology, high emotion and people-oriented.

In methodology, modernism follows the absolute role of physical attributes, standardization, integration, industrialization, high efficiency and high technology. Postmodernism follows the dominance of human experience, the unity and continuity of time and space, the interpenetration of history, individuality, laxity and liberalization.

In terms of design language, modernism follows the form of function determination, "less is more" and "useless decoration is a crime" (Russian); Post-modernism follows the diversity, fuzziness and irregularity of forms, with a double interpretation of one or the other, emphasizing historical context, image metaphor and "less is boring"

The famous saying of "function determines form" and the principle of "less is more", which are regarded as classics by modernism, ignore social progress and people's needs. Da Lu said: "Materials and decorations are the cells that make up products". Functionalism opposes decoration because it treats design with a rational and logical attitude. The present era is different from before, the relationship between people and the world has become more complicated, and people's aesthetic taste and quality of life have also become higher. Therefore, the principles of functionalism and reductionism followed by modernist design are increasingly challenged and questioned.

On the issue of form, postmodernists engage in new eclecticism and technicalism, which are superficial things. Therefore, those who oppose postmodernism believe that modernism is an all-round revolution in architectural thought, while postmodernism is only a popular style in architecture and cannot last long. The social and historical significance of the two cannot be compared.
