A new imagination and aspiration on beauty gradually forms to complete the public art policies, to elevate the gradation of beauty in public spaces, to prompt artists to walk out their own studios to hug the public, and to enlighten citizens to be more aware of environmental beauty. Artists are able to install aesthetic factors before the formation of urban landscape so that the cities are no longer dull and mundane. The spirit of the public art foundation is included in this year’s regulation on public art installation in order to let public art get rid of the destiny of being dependent on new constructions; the new regulation broadens the limits on the forms of public art works and enables the option for architectures to be part of public art. Under the guidance of the elastic regulation, the public art foundation becomes the essential booster for cities to shape their own city style.
