Emperor Wen of Han attached great importance to agricultural production. After he acceded to the throne, he issued imperial edicts many times to persuade farmers to teach mulberry, set up a number of employees according to the proportion of household registration, and often gave rewards to encourage farmers to develop production. At the same time, he also pays attention to reducing the burden on the people. In the first two years (before 178) and the first twelve years, Wendi "reduced the rent by half" twice, that is, the rent rate was reduced to 30 tax, and the rent was completely free in the first thirteen years. Since then, the Han Dynasty has customized thirty taxes. During the reign of Emperor Wendi, the tax was reduced from 120 yuan per year to 40 yuan per person, and the corvee was reduced to once every three years. In the second year of Emperor Jingdi (before 155), he changed the summer season of Qin Dynasty 17 to 20 years old, while the summer season of writing Han law was 23 years old. In addition, Emperor Wendi also issued the imperial edict of "forbidding Chishanze", that is, opening the forests and rivers originally owned by the state, thus promoting the development of farmers' marginal production and salt and iron production, which are closely related to the national economy and people's livelihood. Twelve years ago, Emperor Wendi also abolished the system of customs clearance orders, which was conducive to the circulation of goods and economic ties between regions. It also promoted the development of agricultural production. Emperor Wen of Han also carried out major reforms in criminal law since Qin Dynasty. (1) Criminals in the Qin Dynasty, that is, those who were sentenced to official service and were heavier than official service, mostly had no prison term and served hard labor for life. Emperor Wendi issued a decree and re-enacted the law, stipulating the term of imprisonment according to the seriousness of the crime; A sinner will be exempted from serving his sentence as Shu Ren. (2) According to the Qin law, the parents, brothers, sisters, wives and children of sinners should sit together, and the heavy ones should be put to death, while the light ones should be buried as official servants, which is called "sitting by death". Emperor Wen explicitly abolished it. (3) There were four kinds of corporal punishment in Qin Dynasty, namely, beating, licking, gouging out and palace. Emperor Wen of the Han Dynasty abolished flogging, flogging and gouging and replaced them with flogging. Emperor Wen of Han also reduced flogging. These reforms are of great significance, but the latter two items were not seriously implemented at that time and later. During the reign of Emperor Wendi, many officials were lenient, not demanding, so prison affairs were simple and the oppression suffered by the people was significantly reduced compared with that in Qin Dynasty.
