Architecture,often viewed as the most conspicuous human art,adorns public spaces with meaning and embodies the philosophical and cultural spirit of its era.It is the essence of what makes a city unique.Therefore,the study of the art industry must include an exploration of the artistic attributes of urban space.In postmodern architecture,it can be observed that walls increasingly differentiate into two layers,with the outer"skin"playing a significant role in the artification of urban spaces.Due to the advancements in contemporary technology and culture,urban designers and architects now have greater freedom to express their artistic creativity.Guided by postmodern semiotic aesthetics,the shaping of urban spaces has become highly individualized.This individualization allows for a more flexible approach to addressing the two major meta-design challenges:incorporating ethnic style and integrating high and low culture.
