At the beginning of Emperor Wudi's accession to the throne, he continued the policy of preserving health and helping the people carried out by his father before his death, further weakened the power of the vassal, promulgated the decree of feudal lords proposed by Minister Zhu, promoted the vassal's enfeoffment of various factions by the legal system, and forced the vassal's fief to shrink itself.

He set up a secretariat to supervise local governments, strengthened centralization, organized private businesses such as smelting iron, salt and wine into centralized management, and prohibited vassal States from casting money, thus centralizing financial power.

Ideologically, adopting Dong Zhongshu's suggestion of "ousting a hundred schools of thought and respecting Confucianism alone" laid the foundation for the special position of Confucianism in ancient China. Of course, during the period of Emperor Wu of the Han Dynasty, there was no lack of rule of law in the Han Dynasty. At the same time, Liang Wudi also used laws and regulations to consolidate the authority of the government and show its imperial status. Therefore, sinologists believe that this should be based on Confucianism, supplemented by law, and Confucianism outside the law.
