What system was established in the Sui Dynasty and what system was perfected for later generations?

The system of three provinces and six departments and the imperial examination system established by the Sui Dynasty were followed and improved by later dynasties.

The history of Sui Dynasty was from 58 1 to 6 18. It is a unified dynasty in the history of China, which inherited the Northern and Southern Dynasties and the Tang Dynasty, and enjoyed the country for 38 years.

In February of 58 1 year, Emperor Jing of the Northern Zhou Dynasty abdicated to the Prime Minister Sui Wendi, and the Northern Zhou Dynasty perished. Emperor Wen of Sui, Emperor Wendi of the Sui Dynasty, took "Sui" as the title and made Daxing City (now Xi City, Shaanxi Province) its capital.

In 589 AD, the Sui army conquered Chen in the south and unified China, ending the nearly 300-year division of China since the end of the Western Jin Dynasty. Emperor Wen of the Sui Dynasty made great efforts to govern the country, creating a prosperous situation of governing the emperor.

In 604 AD, Emperor Yang Di Yang Guang ascended the throne, and built the East Capital (now Luoyang City, Henan Province) and the Grand Canal running through the north and south, which created a "great cause and prosperous time" for all countries to come to Korea. However, internal and external measures consumed too much national strength, which led to civil strife at the end of Sui Dynasty. In 6 18, Yu Wenhuaji and others launched a mutiny to assassinate Emperor Yang Di; Forced to abdicate, the title is "Tang". In 6 19, the king forced Yang Dong to settle down and gave him the title of Zheng, and the Sui Dynasty was completely destroyed.

Extended data:

Yang Di's national strength was still strong in the early days of his rule. At the beginning of Yang Di's succession, he decided to build Luoyang in Tokyo, dig the Sui and Tang Grand Canal to connect the north and south of China, build the Great Wall, which promoted the economic, social and cultural exchanges and commercial development between the Central Plains and the north and south, and expanded the territory of the Sui Dynasty around it. However, due to Yang Ditai's desire for success and profit, these measures have caused some harm to society.

In the first year of Daye (605), Yang Di sent Su Yang, Yuwen Kai and others to build Tokyo in Luoyang (the capital was changed to Dongdu in the fifth year of Daye) to control the economy of the Central Plains and Jiangnan. National granaries were built in Luokou and Luo Hui around Luoyang to prepare for famine, and Luoyang Miyagi (Wei Zi City) was built. As he has to serve two million people every month, Yang Di pays attention to the perfection and luxury of Luoyang.

In order to communicate the traffic and economic development of Jiangnan Economic Zone, Central Plains Political Zone and Yan, Zhao, Liaodong and other military regions, Yang Di promoted the construction of the Grand Canal, which connected many water systems in China and formed a traffic network running through the north and south. It has promoted the development of coastal cities, and many industrial and commercial cities have sprung up like mushrooms after rain, which has promoted the cultural development and ethnic integration in various regions and accelerated the Chinese civilization to become an organic whole of Oriental civilization.
