Emperor Wu of the Han Dynasty weakened the power of the vassal, and promulgated the conferring decree proposed by minister Zhu (y m 4 n), which promoted the vassal's enfeoffment by law, so that the vassal's fief had to be reduced by itself.

During the period of Emperor Wudi, there was no lack of rule of law in the Han Dynasty. While promoting Confucianism, Emperor Wu of the Han Dynasty consolidated the authority of the government and showed the status of imperial power through laws and regulations and criminal law.
