It can be said that many systems in the Sui Dynasty are unprecedented and epoch-making. Only by establishing so many excellent political systems can the Sui Dynasty have such a strong national strength and leave so many historical and cultural heritages.
Many projects in the sui dynasty were flawed at that time, and their merits were behind. At that time, the Grand Canal was dug in Sui Dynasty, which consumed huge material and financial resources. However, this Grand Canal connects the North-South economy, making it easier for businessmen to communicate with each other, opening official warehouses and accumulating grain. It is said that the grain stored in the granary in the Tang Dynasty was accumulated in the Sui Dynasty. But with so many epoch-making policies and such a strong national strength, why did the Sui Dynasty only exist for 38 years? This is because the reform of the Sui Dynasty touched the interests of all aristocratic families and big landlords, and the opponents were huge and numerous. Moreover, the construction of the Grand Canal consumed too much financial and material resources, consumed too much national strength, caused the rebellion of aristocratic families, and led to the demise of the Sui Dynasty.
Although the Sui Dynasty perished, the inter-generational political system established by the Sui Dynasty remained, and the Grand Canal built during the Sui Dynasty also played an important role.
