Political aesthetics is an interdisciplinary subject of politics and aesthetics, and it mainly focuses on the theoretical research on political theory and practice from the perspective of aesthetics. Politics and aesthetics have a natural connection at the source, and they show different connotations in different historical periods. Since the 18th National Congress of the Communist Party of China, the strategy of social governance under the new historical conditions with Xi Jinping as the core has presented distinct aesthetic implications in many respects, which can be divided into three levels: from the perspective of concept, the mainstream ideology of the new era has shaped some ideological connotations with aesthetic implications successfully; from the perspective of system, the construction of the system of institutions in the new era presents the beauty of harmony, rhythm and transparency; from the perspective of leader, the political authority of the new era demonstrates the charisma of the extraordinary leader, all of this require systematic demonstration and explanation.
