1, promoting economic recovery and development: the recuperation policy is conducive to improving people's livelihood and people's living standards. It was subjected to scuffles and tyranny during the Warring States Period (476 ~ 22 BC1), the Qin Dynasty Period (22 1 ~ 207 BC) and the Chu-Han War Period (206 ~ 202 BC).

2. Conducive to the stability of the Western Han Dynasty: At the beginning of the establishment of the Western Han Dynasty, there were internal separatist forces and factional struggles such as governors and tyrants within the central government. Externally, there are separatist regimes of Fujian-Vietnam regime, Dong 'ou (Ouyue) regime and South Vietnam regime in the southeast, and the threat of the northern nomadic Xiongnu regime's continuous southward invasion makes its national strength very weak. After 60 years of recuperation in the early Han Dynasty, the economy of the Han Dynasty resumed development, the population grew rapidly, the military strength was steadily improved, the political situation changed from turmoil to stability, the rebellions in various places were gradually calmed down, and people's lives were stable. By the time of Emperor Wu of the Han Dynasty, the Western Han regime had the strength to crack down on separatist forces at home, strengthen centralization and expand its territory abroad.

3. It is conducive to the restoration and stability of social order: after eight years of war between the peasants in the late Qin Dynasty (209-207 BC) and the Chu-Han War, the social order was seriously destroyed, the various systems of the Qin Empire tended to collapse, the legal system ceased to exist, a large number of people were exiled or hidden, and the labor force (farmers) was separated from the means of production (land). The policy of preserving health and raising interest in the early years of the Western Han Dynasty was conducive to the restoration of a unified centralized monarchy and the re-integration of farmers and land. After the normal social order is restored, it is conducive to the long-term stability of the social order and the cultivation of people's loyalty to the political power to continue to pursue the "learning from Huang Lao" and implement the policy of rest and recuperation.
