The policy of rest and recuperation means that after the great turmoil or long-term war, the rulers do not consume people's money and impose heavy punishments on the people, but adopt a policy of lenient punishments and thin taxes to 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 rulers (Hui Di, Lv Hou, Wendi and Jingdi), the policy of recuperation has been implemented for 60 or 70 years. The result is "all rivers run into the sea, and the national strength is considerable." During the reign of Emperor Gaozu Liu Bang, in order to share the interests with the people, in addition to demobilizing soldiers, letting those who fled in the war go home and releasing those who sold themselves into slavery as civilians, the following measures were taken: (1) Adjusting and establishing a new system. (2) suppress businesses. Businessmen are forbidden to be officials, wear silk fabrics, carry weapons and ride horses, and heavy taxes are imposed on businessmen. (3) Pro-Huns. (4) Eliminate the king with different surnames and enfeoffment the king with the same surnames. Like killing Han Xin and Peng Yue for treason. On the one hand, Emperor Gaozu adjusted the relations of production to meet the needs of the development of productive forces and consolidated the feudal economic foundation; On the other hand, a set of ruling system of the Western Han Dynasty was initially established, and the feudal superstructure established since Qin Dynasty was restored and perfected, which laid the foundation for the prosperity of the Western Han Dynasty. Reason: The peasant war was turbulent at the end of Qin Dynasty, and the Chu-Han dispute caused untold sufferings. They needed time to recuperate and rebuild their homes, which was not superior to the Xiongnu forces in the north.

Main measures: implement the system of enfeoffment, reward farmers to raise silkworms, reduce rent and interest, and implement the policy of giving priority to agriculture.

Function: The Han Dynasty won precious time, strengthened its national strength, and emerged a prosperous time for the founding of the People's Republic of China, which laid a strong material foundation for Emperor Wu of the Han Dynasty to drive Xiongnu to the north. Main measures: Emperor Gaozu: disarm and return to the fields, persuade the people to return to their hometowns, release slaves for the people, and pay fifteen taxes and one tax; Emperor Wendi and Emperor Jingdi: Lighten taxes and reduce punishment.

Influence: The Han Dynasty won precious time, and its national strength was enhanced, resulting in the founding of the country, which laid a strong material foundation for Emperor Wu of Han Dynasty to drive Xiongnu to the north.
