In the early Western Han Dynasty, the policy of "rest and recuperation" was implemented. Huang Lao thought that the reasons for implementing the policy of rest and recuperation were: 1. The early Han Dynasty was a scene of ruin: population decline, economic depression and food shortage. The economic depression in the early Han dynasty was not conducive to consolidating the rule, so production must be restored and developed. Secondly, it is pointed out that the cloth general of Emperor Gaozu came from humble origins and took part in the uprising to overthrow the Qin Dynasty. Therefore, they pay attention to drawing lessons from the demise of the Qin Dynasty and studying how to avoid repeating the same mistakes. Minister Lu Jia gave Liu Bang advice for this purpose. Liu Bang, who is also from humble origins, can also accept Lu Jia's advice. According to Liu Bang's request, Lu Jia wrote 12 copies of the memorial in succession, and put forward the policy of lenient education. The heavy service and harsh laws of the Qin Dynasty led to its demise, so we should learn from the lessons of the demise of the Qin Dynasty, accept Lu Jia's suggestion, and implement a lenient policy of caring for the poor and paying taxes. Compared with the tyranny of the Qin dynasty, recuperation can make farmers live and work in peace and contentment, stabilize social order and help to establish a new ruling order. Emperor Wen of Han Dynasty and Emperor Jing of Han Dynasty are two generations of emperors who continued to implement the policy of "rest and recuperation" after Emperor Gaozu of Han Dynasty and achieved remarkable results, so they are known as "the rule of culture and scenery".
