Taking the State of Qin as an example, Shang Yang's idea of promoting the rule of law was immediately put into practice. Because of the infringement on the interests of princes and nobles, Shang Yang's death was inevitable, because the strength of Qin had to take the road of reform, and Shang Yang dared to put it forward. The core of reform is to establish a country ruled by law, and princes and nobles commit the same crimes as ordinary people. This laid the foundation of Qin State. Only on this basis can we promote land reform, military reform and economic reform, and make the country rich and strong with sufficient legal support.

Ying Zheng, king of Qin, was able to unify the six countries, ended the long-term separatist regime and established a vast country with Xianyang as its capital. Ying Zheng, the king of Qin, adopted the legendary title of Three Emperors and Five Emperors and declared himself the first emperor of this country. Descendants passed down from generation to generation, claiming to be Emperor II, Emperor III and even Emperor Shiwan, abolished posthumous title, stipulated that the emperor called himself "I", and formulated a system of courtiers and documents that respected the monarch and suppressed the ministers.

But the severity of the law is still surprising. Evaluating the severity of a country's laws should not be limited to how severe people are punished for breaking the laws, but also from the perspective of how deeply it restricts people and how much it affects people's daily lives. Qin law has a profound influence on people's behavior and thought. In the management of people, the household registration system is strictly implemented. This household registration system is much stricter than we are now. In addition to surnames, there are also very specific personal information such as skin color and income.

In people's production, the management of plows is particularly strict. The government issued farm tools to farmers and put them on record, requiring them to use them every three years. If there is any damage during this period, it needs to be reported to the government for compensation. If the tools are not damaged during the period, new farm tools can be obtained. It can be seen that the Qin Dynasty had a ubiquitous and pervasive management system for people's production and life, which bound people's daily life, even if they were farming, they should always be careful.

The most famous system in Qin Law's military management is "sitting together", which has shaped an era of collectivism and profoundly changed people's behavior and values. The management of the Qin army, in addition to everyone's establishment, such as infantry 200, 500, general 100, commander 50, commander 10, commander 5, honor and disgrace and * * *.

Reward and punish each small group, and the criterion of success or failure is to subtract the number of casualties on both sides in the war. Less casualties on our side means victory. This system of "sitting together" makes everyone dare not act rashly, and they should not act rashly when monitoring each other. Individuals live under the pressure of collectivism, otherwise your hometown will be severely punished for you.
