This laid a solid foundation for Emperor Wu of Han Dynasty to crusade against Xiongnu.
(202 BC-65438 BC+0465438 BC+0 BC) The policy of "rest and recuperation" is often adopted in Chinese history. The policy of rest and recuperation refers to that after the great turmoil or long-term war, the rulers do not engage in the rule of wasting people's money and imposing harsh laws, but change to the policy of lenient punishment and thin taxes, maintain the people's strength and multiply the population, so as to achieve the purpose of restoring and developing the economy and stabilizing the rule. After several generations of emperors (Hui Di, Lv Hou, Wendi and Jingdi), it was implemented for 60 or 70 years. The result is that "the country is rich and strong, and its national strength has increased." Ban Gu said, "Han Xing, clean up your troubles and share the interest with the people; As for filial piety, it is a combination of courtesy and frugality; Filial piety follows the industry. In 50 or 60 years, as for changing customs, the people are mellow. " After Emperor Gaozu's inaction, in view of the experience of Qin's death, he adopted the Taoist concept of "governing the elderly by Huang" and "governing by inaction" in policy. The Western Han Dynasty was full of lofty sentiments.
First of all, the "county system" was adopted, and counties and feudal countries coexisted. The central government practices the same county system, while the local governments practice feudalism. The emperor separated the vassal state from the kingdom, in which the vassal state only enjoyed the tax in the fief and had no military and political power, and was under the jurisdiction of the county, while the kingdom had independent political and military power. In addition, domestic attention should be paid to building water conservancy projects and reducing taxes to create conditions for restoring agricultural development. Pro-Huns and maintain peace in border areas. These policies in the Han Dynasty generally maintained peace for a period of time, but they also caused a series of problems. In China, the frivolous tax policy has made some local powerful forces grow stronger and stronger, forming land annexation. Externally, Xiongnu frequently invaded Japan, threatening peace in the border areas. In addition to implementing these policies, Emperor Gaozu also had doubts about the princes with different surnames who had made great contributions to the dispute between Chu and Han. At this time, Han Xin was executed by Xiao He and Lv Hou, and then Peng Yue, Ying Bu and others were eliminated one after another. Almost all the recruited princes disappeared and were replaced by princes of Liu. Liu Bang said a word to everyone in the White Horse Alliance: "Not Liu.
After the death of Lv Hou's great-grandfather, the regime was gradually in the hands of Lv Hou, the great-grandfather. After his death, Lv Hou established two puppet emperors and gradually weakened the Liu family. This situation lasted for eight years until Lv Hou died. Zhou Bo and Chen Ping seized the imperial power and killed Lu Chan and others. The protagonist is more dissatisfied with Lu's authoritarian power, and Qiu and the prime minister plot to seize Lu's military power. Since Emperor Gaozu had only two sons left, the courtiers took Zhao, the Empress Dowager of Huainan, as their soil and took care of her family. Therefore, he welcomed the puppet emperor established by Lv Hou as the Emperor of China on the grounds that he was not his own. He lightened the burden on the people and the punishment. After his son King Jing ascended the throne, he also. Therefore, this period is called "the rule of cultural scene" in history. Wenjing No.2 Imperial Capital is an advocate of Taoist thought, advocating inaction. During this period, the country developed steadily and its national strength was greatly enhanced. However, during the reign of Emperor Jingdi, he listened to Chao Cuo's advice and cut off the vassals. His haste led to the "Wu Chu Qi Rebellion", which was the only turmoil in this period and lasted less than a year. The imperial court tried to deprive the governors of their power and strengthen centralization. During this period, the Western Han Dynasty adopted a "kinship" policy towards the Xiongnu, that is, the princess was married to the Xiongnu royal family and a lot of materials were given to the Xiongnu. However, the Xiongnu still invaded the territory repeatedly, and the border troubles became more and more serious. However, the rule of Wenjing made the national strength of the Western Han Dynasty unprecedented, which laid the foundation for a large-scale counterattack against the Huns later.
