We often say "the prosperous era of the Han and Tang Dynasties", "the rapid economic development of the Tang and Song Dynasties", the Wenzhi martial arts and international prestige of the Han Dynasty and the Tang Dynasty were relatively strong, the Han Dynasty seriously defeated the Xiongnu, opened up the western region, the Huaxia gradually became known as the "Han nationality", the language spoken was called "Chinese", and the written text was called "Chinese characters".
Not to mention the prestige of the Tang Dynasty in the world, the place where chinese people live abroad is called "Chinatown". The Song Dynasty is China's history of commodity economy, culture and education and scientific innovation is highly prosperous era, some people have studied the history of the Song Dynasty, calculated that in 1000, China's total GDP was 26.55 billion US dollars, accounting for 22.7% of the total world economy, per capita GDP of 450 US dollars, more than the 400 US dollars in Western Europe at that time.
However, some scholars have studied the history of China's feudal dynasties for more than 2,000 years and found that the dynasty that should not be destroyed is the Sui Dynasty. The Sui Dynasty can be said to be a meteor in the history of our country, it is brilliant, but it is short-lived, lasting 38 years.
Before the Sui Emperor Yang Jian established the Sui Dynasty, China experienced 300 years of turmoil and division. Emperor Wen of Sui's father, Yang Zhong, was a famous general of the Northern Zhou Dynasty and had made great military achievements, so he was given the title of "Duke of Suiguo", but Emperor Xuan of Northern Zhou was drunk and had five empresses at the same time, one of whom was Yang Jian's eldest daughter Yang Lihua.
After the death of Emperor Xuan of Northern Zhou, Yang Jian, who was the head of the Guanlong Gate Valve, gradually took control of the imperial government, and in 581, emperor Jing of Northern Zhou was located in Yang Jian, and Yang Jian opened the Sui Dynasty as Emperor Wen of Sui, and by 590, Emperor Wen of Sui had completed the unification of the country.
And Emperor Wen of Sui took "since ancient times emperors have not had good luxury and can be elderly" as a creed in life, advocating frugality in life, and the concubines in the palace are not beautiful ornaments, according to records, Emperor Wen of Sui once wanted to use hu powder and woven collars, but searched the entire palace and did not find it.
Due to the implementation of the nine-pin Zhongzheng system during the Wei and Jin Dynasties and the Northern and Southern Dynasties, the selection of officials did not first look at their ability, extremely important birth and background, from civilian families but talents with outstanding talents did not have a place to use, Sui Wendi deeply felt a pity, so he issued an order, the appointment of officials is not limited to the door, meritocracy, pass the examination to obtain a soldier.
In addition, Emperor Wen of Sui also deposed more than 200 corrupt officials and corrupt officials; deleted the torture of the previous generation and formulated Sui laws; he also lightened the burden on the people by lightly dispensing with thin gifts, reducing the burden on the people; and in order to prevent hunger in Jigu, the Sui Dynasty set up warehouses, dividing the official warehouses and the righteous warehouses.
Although Emperor Wen of Sui cried out bitterly before his death: "Beast Sheng (Yang Guang) He Foot Pays Big Things!" Alone and misled me! However, after Yang Guang ascended the throne as the Sui Emperor, he also opened up a "great prosperity", he excavated the Sui and Tang Grand Canal with Luoyang as the center, promoted ethnic integration, and planned to move the capital to Luoyang, so as to control the economy of the Central Plains and Jiangnan. Due to the strong national strength, the Sui Emperor was committed to expanding the territory, but the Sui Emperor was somewhat eager to achieve quick success, and all aspects needed human, material, and financial resources, so naturally bad evaluations began to appear.
However, the demise of the Sui Dynasty was not only due to the Sui Emperor's western conquest of Tuguhun and the three expeditions to Goguryeo, and the mobilization of the people to dig the Grand Canal, but also partly because of the Door Valve Clan, and some of the measures of the Sui Emperor touched the interests of the Gate Valve Clan.
Hu Ji, who has long been engaged in the teaching and research of Sui and Tang history in modern times, said: "At the historical juncture of China's transformation from the aristocratic politics of the door valve to the bureaucratic politics of the imperial examination, and from the door valve society to the society behind the door valve, Yuwen Tai, Yuwen Yong, Yang Jian, Yang Guang, Li Shimin, and Wu Zetian all made historic contributions, among which the sui emperor and Wu Zetian who went the farthest in political reform were the Sui Emperor and Wu Zetian. But the latter two are the most dirty in history. ”
In fact, during the reign of the Sui Emperor, the national strength was still strong, otherwise in just a few years from the fall of the Sui Dynasty to the reign of Tang Taizong, it would not have been possible to have a situation of "rule of Zhenguan".
