The Republic (about 300,000 words in Chinese translation) is Plato's masterpiece. The book consists of ten volumes, which is an important embodiment of Plato's idealistic philosophy applied to social politics. In the book, Plato expounded his national view in the form of dialogue, involving economic, ethical, educational, literary and artistic issues. The main content can be divided into three parts: clarifying the emergence and composition of the state; To stipulate the relationship between domestic residents; This paper discusses the advantages and disadvantages of Greek city-state politics.

The Republic is the first utopian work in history, which has a great influence on the early utopian society in Europe. However, such an ideal is doomed to be difficult to realize in the face of the complex real world, and Plato himself had to make some amendments to it in his later years.
