The first aspect, political system reform, has strengthened centralization. Emperor Wendi of Sui Dynasty abolished the old system and basically established a system of three provinces and six departments, with a clear division of labor and strict organization. The reform of the political system is based on centralization, which solves the problem that power is too concentrated in individual posts in the old system, which is the progress of the political system.
The second aspect is to promote economic development and ensure people's lives. The Sui Dynasty carried out "judging by appearance" and "judging by loss of registration", which improved the national household registration system and correctly estimated the national population. Granaries have also been set up in various places to prepare for the year of famine and ensure that people have food. It also unifies the currency, which is also conducive to the trade flow of businessmen. On the basis of ample food and clothing for the people, emperor Yang Di's thrifty economy will not increase the financial burden.
Thirdly, unifying the whole country and reforming the military system promoted the long-term stability of the Sui Dynasty. During the reign of Yang Di, soldiers also needed to farm in peacetime, and the "integration of soldiers and farmers" was implemented. This will not only enable the army to have something to do in peacetime, but also promote agricultural development and make soldiers self-sufficient without increasing the burden on the people.
To sum up, Emperor Wendi of Sui Dynasty, Emperor Wendi of Sui Dynasty, was indeed a wise monarch who governed the country well. Although he has the name of brutal murder, he did make great achievements in governing the country. Personal opinion, hope to adopt.
