In the second year (before 178) and the twelfth year (before 168), Wendi "cancelled half of the land rent tax" twice, that is, the rent rate was finally reduced to 30 tax. For thirteen years, Wendi was also free of rent. At the same time, it is not easy to send troops to neighboring hostile countries to maintain peace, so as not to consume national strength. This is a frivolous and generous policy. Wendi Deng's life is also frugal. No riding clothes are added to the palace, clothes are not mopped, curtains are not embroidered, and counties are forbidden to contribute exotic things. Therefore, the expenditure of the state was restrained, and the aristocratic bureaucrats dared not be extravagant, thus reducing the burden on the people. This is a rest and recuperation policy. Emperor Wen of the Han Dynasty attached great importance to agriculture and ordered many times to persuade farmers to teach mulberry. According to the proportion of registered permanent residence, he set up a number of people, such as Sanlao, Filial Piety and Tian Li, and rewarded them to encourage farmers to produce. After the death of Emperor Wendi, Emperor Jingdi ascended the throne and initially put down the rebellion of the Seven Kingdoms. After the Seven Kingdoms Rebellion, Emperor Jingdi began to concentrate on managing state affairs. It is said that Jingdi is very simple and kind, and loves the people. In addition to pacifying the rebellion of the Seven Kingdoms, there was no large-scale use of troops, and the war with Xiongnu was always controlled within a certain scale, and the pro-Xiongnu policy was still adopted. Jingdi advocated the theory of Huang Lao, reduced punishment, reduced taxes, built water conservancy projects, advocated agriculture, and demanded retrial of cases that people were dissatisfied with to avoid unjust imprisonment. The people have created a lot of wealth in a peaceful and stable environment. During this period, the people were rich, well-fed, lived and worked in peace and contentment, and the world was peaceful and happy.
