(1) Subjectively, the Han Dynasty highly praised Huang Lao's medical skills. At the end of Qin dynasty, there were years of war and people's livelihood was depressed. After the establishment of the Western Han Dynasty, it is urgent to unify thoughts and stabilize people's hearts. However, after the reunification of the country in the early Han Dynasty, there were great differences between the eastern and western cultures, which required an idea to unify them. At this time, the thought of governing the situation by doing nothing not only learned the lessons of Qin's death, but also adapted to the needs of the policy of recuperation in the early Han Dynasty. After Liu Bang established the dynasty, he immediately asked Lu Jia to summarize the lessons of Qin's death as a reference. According to Huang Lao's thought and the social situation at that time, Lu Jia put forward that "many things are chaotic, and many times are chaotic;" Law is greater than the son, and rape is greater than the pool, so "Tao is greater than inaction". At this time, Huang Lao's thought was highly valued by the political society, and all officials from the emperor to the court respected it. Emperor Han and Dou Taihou "said the words of Huangdi and Laozi, and Jingdi and Dou read Laozi and respected his skills", while Xiao He, Cao Can, Liu An, Ji An, Chen Ping, Lv Hou, Sima Zhu Ji, An Qiusheng, Wang Sheng and Huang Sheng were also famous followers of Huang Lao's thought. Under the situation that Huang Lao's thought occupied the mainstream of society, the whole political society in the early Han Dynasty ruled by Huang Lao's inaction, sharing interest with the people and ruling by hanging arch.
(2) Objectively speaking, any dynasty needs to develop production, settle down and recover after experiencing great national turmoil. At the beginning of the Han Dynasty, due to the tyranny of the Qin Dynasty and years of war, social production was seriously damaged. The rulers need a relatively stable situation, so that the people can recuperate, resume and develop production and consolidate the newly established feudal regime. It is recorded in Hanshu Shihuozhi that "Han Xing, after the disadvantages of Qin Dynasty, the governors rose together, the people lost their homework, and they were hungry and cold. Five thousand stones per meter, people eat each other, and more than half of the dead. " It can be seen that the social and economic situation in the early Han Dynasty was extremely bad. At the same time, after the turmoil of the peasant war and the dispute between Chu and Han in the late Qin Dynasty, people were devastated. Compared with the military strength of Xiongnu in the north, the regime in the early Han Dynasty was not dominant, and it needed time to recuperate and change the situation of social and economic decline. Huang Lao's thoughts such as "governing by doing nothing", "being frivolous" and "sharing interest with the people" just adapted to the requirements of this era, thus recuperation became the concept of governing the country in the early Han Dynasty. The practice of this concept of governing the country also proves that the policy of rest and recuperation is effective. According to "Historical Records", after hard work, "both the monarch and the minister want to rest and do nothing, so Hui Di hangs his arch, and the high-ranking daughter is called the system, and the government cannot leave the government, and the world is natural." Punishment is rare, and sinners are hope. People's affairs are cultivated, and food and clothing are also cultivated. "Recuperation made the Han Dynasty win valuable time, enhanced its national strength, brought the founding prosperity of Wenjing rule, and laid a strong material foundation for Emperor Wu of the Han Dynasty to drive Xiongnu to the north.
