Law is one of the top ten famous scholars in the Warring States period, which evolved from the legalist thought. After being popularized by Sun Bin and Han Feizi, it was used by vassal states during the Warring States Period. Legalism is related to the emergence and development of feudal land relations in China, which is the theoretical expression of the landlord class replacing the slave owner's aristocratic rule. In slave society, "courtesy" is the political system and moral standard ruled by slave owners and nobles. In order to meet the needs of the development of feudal land relations, a number of reformers appeared among the slave owners and nobles, such as Guan Zhong of Qi State, Guo Si of Jin State and Zi Chan of Zheng State. They promulgated laws and punishment books, reformed the land tax system, promoted the process of feudalism, and became the pioneers of legalism in the Warring States period. Both Guan Zhong and Zi Chan emphasized legal system and moral education. Philosophically, they expressed some materialistic views. Guan Zhong and his successors put forward the viewpoint that "the sky remains unchanged, and the earth is not easy to make", while Zi Chan put forward the proposition that "the sky is far away, the people are close, and it is unattainable", acknowledging that nature has its objective laws and opposing the superstitious concept of heaven-man interaction.
The historical significance of the thought of making a fortune lies in providing quite effective theoretical basis for the later centralized Qin Dynasty to formulate various policies. The later Han Dynasty inherited the centralized system and legal system of the Qin Dynasty, and was the political and legal subject of the ancient feudal society in China.
However, it is worth noting that the development of ancient jurisprudence overemphasized the rule of law, which led to cruel officials running rampant and severe punishment for the people.
