Emperor Gaozu adopted a lenient ruling policy while eradicating the king with different surnames and stabilizing the frontier. Five measures of emphasizing agriculture and restraining business are emphatically put forward, that is, the main content of rest and recuperation policy. (1) stopped and returned to agriculture, which expanded the ruling foundation of the Han Dynasty. The shift of foot soldiers to agricultural production is conducive to restoring the destroyed social economy. (2) The restoration of Juetian not only fostered and protected a number of landlord economies, but also contributed to the stability of feudal social order. (3) Releasing handmaiden is one of the ways to increase the population of agricultural labor force and solve the financial difficulties of the country. (4) The policy of restraining business aims at preventing the agricultural labor force from dispersing, protecting the small-scale peasant economy and increasing the national fiscal revenue. (5) reducing the land rent to stimulate the enthusiasm of workers; But it only reduces the "land rent" and does not involve anything else. Compared with the Qin dynasty, the labor burden of farmers in the Han dynasty was relatively reduced.

The role of rest and recuperation: (1) is conducive to the establishment of a new ruling order; (2) Giving farmers some land and working hours is conducive to social and economic recovery; (3) enhanced the economic strength of feudal countries.
