Historically, Han Fei was a master of legalism in the pre-Qin period. His thought of rule of law adapted to the historical environment of managing troubled times at the end of the Warring States Period and made great contributions to the unification of China by Qin. Governing the country according to law and building a socialist country ruled by law is the general plan of governing the country put forward by the central government. Han Fei's thought of rule of law was formed when the etiquette system was seriously damaged at the end of the Warring States Period.

With law as the core, the concept of combining law, technique and potential has transformed the traditional legal culture, which has realistic and targeted guiding significance for the rule of law construction in modern China. Reforming the rule of law and strengthening the country is an important content of Han Fei's thought. Han Fei analyzes human history from the historical point of view of evolution. He saw the development of human history and used this concept of development to analyze the past, present and future of human society. It has a strong reference significance for China's current reform and opening up.
