Emperor Wu of the Han Dynasty was the first emperor in China to use the title of the year. After he succeeded to the throne, he inherited his father's business, weakened the vassal power, and issued a promotion decree put forward by minister Zhu, so that the vassal could seal their son Hou, which split the vassal fief. At the same time, he introduced the official title of secretariat to strengthen local control. Militarily and economically, he also strengthened centralization, putting iron smelting, salt making, wine making and other things under central management. At the same time, he forbade the vassal States to cast money, so that the finances were concentrated in his hands. He adopted Dong Zhongshu's suggestion of "ousting a hundred schools of thought and respecting Confucianism alone", paving the way for the special position of Confucianism in ancient China. However, it is generally believed that he used Confucianism to unify his thoughts, and at the same time used spells and criminal names to strengthen his rule, which is the so-called "expressing Confucianism in the law." Ji An and Sima Qian's castration, which were actively used at that time, are famous examples.

At the beginning of Liang Wudi's accession to the throne, on the one hand, the political situation was relatively stable and the national economic situation was relatively good. On the other hand, the separatist factors of vassal countries still exist. Therefore, while continuing to implement the policy of Emperor Jing of Han Dynasty, he took a series of measures to strengthen the centralization of absolutism. Politically, first, the "favor decree" was promulgated, which allowed the captaincy to enfeoff more children and divide the fiefs of the kingdom, further weakening the power of the captaincy; Secondly, the establishment of China and North Korea weakened the relative strength and consolidated the sacred position of imperial power; Another 13 secretariat departments were established, which strengthened local control. On the military side, it is mainly to concentrate military power and enrich the central military power; On the economic front, we should rectify the finances, issue the orders of "liquidation" and "admonition", levy a tax on businessmen's assets, and crack down on wealthy businessman dajia; Sang Hongyang suggested that smelting iron and boiling salt should be returned to the official camp, and it is forbidden to cast money in counties and counties; 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" ideologically are beneficial to the development of agricultural production, adopting Dong Zhongshu's suggestion, ousting a hundred schools of thought, and exclusively respecting Confucianism, making Confucianism the dominant ideology of China society and having a far-reaching impact on the politics, society and culture of China in later generations.

On the one hand, he sent Wei Qing and Huo Qubing to conquer the Huns, which relieved the threat of the Huns and ensured the economic and cultural development of the north. He wiped out the Yelang and Nanyue regimes, and successively established seven counties in the southwest, so that today's Guangdong and Guangxi regions returned to Chinese territory after the Qin Dynasty. At the same time, Zhang Qian was sent to the Western Regions to open up the Silk Road, strengthen the rule of the Western Regions and develop economic and cultural exchanges between China and the West. In the East, he sent troops to destroy Wei's Korea (Korea) and set up four counties: Le Lang, Xuantu, Lintun and Fan Zhen.
