It also seeks reasonable public space and open meaning for the realization of people's public demands, so as to guide the self-survival and lifestyle transformation of social members in the pursuit of the value of Chinese modernization to promote human society based on and beyond the self-liberation of the proletariat and the free and comprehensive development of human beings. It also provides a more effective way to realize the organic integration of common ideal with real public and public space.
