What did the Ming emperor Judy do?

Judy was another successful emperor after Zhu Yuanzhang in Ming Dynasty. During his 22-year reign, he made five northern expeditions, which dealt a heavy blow to the remnants of Mongolian aristocrats and consolidated and safeguarded the unity of multi-ethnic feudal countries. He continued to carry out Zhu Yuanzhang's reclamation policy. In May of the first year of Yongle (A.D. 1403), it was ordered that "the amount of taxes should be removed from the uncultivated fields in the world" in order to dredge rivers and lakes, reduce taxes and relieve victims. In the third year of Yongle (A.D. 1405), the land rent of the four houses of Su, Song, Jia and Hu was removed at one time. The implementation of these policies is conducive to the recovery and development of agricultural production. Handicraft industry and commerce are also very prosperous. Iron smelting in Zunhua, porcelain making in Jingdezhen, shipbuilding in Nanjing and textiles and silk in Songjiang have all reached a high level. The state's fiscal revenue has increased greatly, and some tax grain is transported to Beijing every year, and there are a large number of warehouses in counties and counties. The economic prosperity in Yongle period is the continuation and development of "the rule of Hongwu". As historians have said, "Gao Taizu became a (ancestor) and enjoyed the country for a long time." In the 1960s and 1970s, granaries were full of food and teeth. " The prosperity of the early Ming Dynasty is inseparable from Judy's continuous reform.
