What effective measures did the Han Dynasty take to form a unified situation?

Politics: In politics, Zhu's suggestion was adopted and an "Enzhi" was promulgated, which weakened the power of vassal states that were enfeoffed in the early Han Dynasty, strengthened centralization and strengthened the supervision system. Emperor Wu of the Han Dynasty also made innovations, including the right to receive photos, the establishment of secretariat, the establishment of a clean government system and other major reforms and innovations. This legal tradition became the basic paradigm of China's imperial system in the next two thousand years. ?

Military: militarily, it is mainly to concentrate military forces and enrich the central military forces; Reform the military system. Wei Qing and Huo Qubing were sent to attack the Huns, which made the northern border counties stable, and Zhang Qian was sent to the western regions, which opened up the land supply channel connecting the western regions and even Central Asia in the northwest frontier.

Economy: in the economic aspect, we should pay more attention to agriculture than commerce, rectify our finances, issue "accounting" and "warning" orders, levy a merchant asset tax, and vigorously crack down on profiteers; Sang Hongyang suggested that iron smelting and salt boiling should be taken back from the official camp, and counties and States should be prohibited from casting money, and five baht should be cast in a unified way; The establishment of leveling officials and loss-sharing officials, as well as the government's management of transportation and trade, have greatly enhanced the country's economic strength. At the same time, building water conservancy projects, emigrating to the northwest and implementing the "land substitution law" are conducive to the development of agricultural production. Another important measure in the economy was to unify the currency at that time.

Thought: Ideologically, Dong Zhongshu's suggestion was adopted, and Confucianism became the dominant thought in China society, vigorously promoted Confucianism, and established imperial academy in Chang 'an. Confucianism became the orthodox thought of China's feudal rule, which lasted for more than two thousand years and had a far-reaching impact on the politics, society and culture of China in later generations. But it also has disadvantages, that is, it is not conducive to the development of ideological diversification.

Personnel: Emperor Wu of the Han Dynasty also attached great importance to the development of talents. He established an inspection and evaluation system, which is the origin of China's systematic talent selection system and has a great influence on later generations.
