After the establishment of the Western Han Dynasty, the "Cloth Bureau" was formed. The emergence of this situation is a summary of the historical change of Qin's death and Han's prosperity. Chen Sheng Uprising put forward that "governors would rather have seeds!" Made important public opinion preparations for cloth to dominate the world. He not only put forward this slogan, but also put it into practice in the uprising struggle. Before the demise of the Qin Dynasty, the Buyi princes headed by Chen Sheng were the leaders of the peasant uprising. The emergence of the Cloth Bureau in the early Han Dynasty was undoubtedly the result of the peasant uprising led by Chen Sheng. The appearance of the situation of cloth clothes is also the inevitable trend of social change since the Spring and Autumn Period and the Warring States Period. As the "Shi Hou Shiqing Bureau" was swept away, the residual form of slave relations was weakened and the feudal rule at that time was transformed. It is a historical progress from "Shi Hou Shiqing Bureau" to "Buyi Bureau" in the early Han Dynasty. The general background and experience of Emperor Buyi had a great influence on his political decision-making, and also affected the internal relations of the ruling group, so that he maintained a certain "Buyi" style. In the early Han dynasty, the hierarchical relationship between monarch and minister was not so strict, and they paid attention to selecting talents and appointing talents, and lived frugally. With the change of social status, the "Buyi" emperor will gradually become a new feudal aristocrat, and his decadent tendency will inevitably increase day by day. The change of ruling policy and guiding ideology in the period of Emperor Wu of the Han Dynasty was the product of the aristocratization of Buyi, which marked the end of Buyi politics in the early Han Dynasty ~
