The founding emperor of Sui Dynasty, whose father Yang Zhong was a military aristocrat in the Western Wei and Northern Zhou Dynasties. In the Northern Zhou Dynasty, Emperor Wudi was named general and Duke Sui. Emperor Wendi of Sui Dynasty inherited his father's title. In the early Tang Dynasty, li yanshou praised Emperor Wendi of Sui Dynasty in "Northern History", saying that "the imperial examination was beautiful, with a beard, and he was seven feet eight inches long, with magnificent appearance and unparalleled martial arts; I know it well and have a slight rate. " Great statesman and national hero. On Jiazi Day in February 58 1 year, Emperor Jingdi of the Northern Zhou Dynasty announced his abdication with the imperial edict of Emperor Wendi of Sui Dynasty. Emperor Wendi of the Sui Dynasty ascended the throne and proclaimed himself emperor, making the country the Great Sui Dynasty, changing the dynasty and granting amnesty to the world. After Emperor Wendi proclaimed himself emperor, he destroyed the back beam in the seventh year (A.D. 587) and wrote a letter to Chen a year later. In the ninth year (AD 589), China was destroyed and unified, ending the nearly 300-year division between Emperor Emperor Wen of Sui of the Sui Dynasty and the Western Jin Dynasty. In the same year, the Ryukyu Islands surrendered to the Sui Dynasty. Emperor Wendi of Sui Dynasty ended the long-term chaos in China and brought China back to an era of peace. After the establishment of the Sui Dynasty, Emperor Wendi carefully managed it, and the Sui Dynasty quickly became strong. He not only accomplished the great cause of unifying China, but also made the Sui Dynasty a powerful country with stable political power, social stability, sharp increase in household registration, rapid increase in reclamation, abundant savings, developed culture, elite armor and extraordinary prestige. A series of reforms have been carried out in the political and economic systems. The central government implements the system of three provinces and six departments, and the three-level system of local counties is changed to the two-level system of counties, and local officials are appointed and removed by the central government, thus consolidating centralization. Emperor Wendi of Sui Dynasty ordered the construction of Daxing City in Xijing (that is, Chang 'an City modeled after the prototype) and Luoyang City in Tokyo. The design and layout of Daxing City had a far-reaching impact on the urban construction of later generations and Japan and South Korea. In 584 AD, Emperor Wen of Sui ordered Yuwen Kai to lead the people to open the Cao Canal. The Weihe River leads from the northwest of Daxing City, slightly along the old Cao Canal in Han Dynasty, and joins the Yellow River in Tongguan, with a total length of 150 kilometers, hence the name Guangtong Canal. This is the beginning of the construction of the Grand Canal connecting two civilizations. Make the Yellow River basin and the Yangtze River basin gradually become one. He put China under the rule of a regime again in a very short time, defended the powerful enemies of Turks and Qidan from the outside, and made the people live in peace and prosperity. Even in the prosperous Tang Dynasty, his great achievements did not completely restore the land area of Sui Dynasty. But the imperial edict is too strict, and many heroes have no good end; Wendi reigned for 24 years and died in Yu Dabao Hall in 604. At the age of 64, he was buried in Tailing (now 5 kilometers west of Yangling (Mausoleum) District in Shaanxi Province).
