Objective: Rich Qiang Bing: Economically, it changed the old relations of production, abandoned mines for land reclamation, and fundamentally established the private ownership of land. Politically, it attacked and disintegrated the old patriarchal clan system, made the feudal state mechanism more perfect, and the construction of centralization began.

Militarily, the purpose of rewarding meritorious military service has been achieved, which has greatly improved the combat effectiveness of the army and created favorable conditions for the next strategic development of Qin State.

Overall significance: Shang Yang's political reform was a thorough reform movement during the Warring States period, which greatly promoted social progress and historical development. Through reform, Qin abolished the old system and established a new system to adapt to social and economic development. The reform promoted the social progress and economic development of Qin State, and at the same time enhanced the national strength of Qin State, realizing its prosperity. It laid the foundation for Qin to unify the whole country in the future and played an important role in the historical development of China.

Shang Yang's political reform was a successful political reform in ancient China, which made A Qin a powerful country, laid the foundation for the unification of the six countries in the future, and determined the idea of rule of law. [2] [3]

Shang Yang absorbed the experience of Li Kui, Wuqi and other Wei Chu legalists, combined with the specific situation of Qin State, further developed the legalist policy, and later came from behind and made great achievements.

He further broke the well field system, expanded the mu system, emphasized agriculture and restrained commerce, rewarded the production of male ploughing and female weaving, encouraged reclamation, and promoted the development of small-scale peasant economy in Qin State.

He generally carried out the county system, enacted laws, established the unified measurement system, and established a centralized monarchy.

He banned private fighting, rewarded meritorious military service, and formulated a system of 20 ranks, which was conducive to strengthening the combat effectiveness of the army.

He cracked down on the old aristocrats who opposed the political reform, and "burned poems" and "books" to make the law clear, so that the political reform could be carried out.

Because of all this, Qin became rich and strong rapidly, which laid the foundation for the unification of China. As Wang Chong said in Han Dynasty:

"Shang Yang's filial piety is a matter for Qin." ("Lun Heng Shu Jie")
