Yang Jian was the founding emperor of the Sui Dynasty, and during his 23-year reign, he not only ended the nearly 300-year division of China since the Three Kingdoms, but also eliminated or severely damaged the Turkic, Tuyuhun, Khitan, Goryeo and other small surrounding states, so that the Tang Dynasty failed to restore the territory of the Sui Dynasty from beginning to end after its establishment. In addition, the Sui Dynasty also pioneered the system of three provinces and six ministries, the law of opening the emperor, the imperial examination system and other systems that had a great impact on later generations, especially the imperial examination selection system that was used until the end of the Qing Dynasty, abolished the nine-grade Zhongzheng system that prevailed in the two Jin Dynasty periods, and abandoned the noble and lowly of origin.
The Cambridge History of the Sui and Tang Dynasties in China puts it this way: "The Sui dynasty eliminated the outdated and inefficient institutions of its predecessors, created a centralized imperial structure, and developed a common cultural consciousness in regions that had long been politically divided, all of which were equally remarkable." One cannot fail to see the achievements of the Sui Dynasty in all its aspects when studying the structure and any aspect of life of the great Chinese Empire that followed, and its achievements are certainly one of the most striking in Chinese history. ”
Yang Jian is also very good at rectifying the corruption of subordinate officials. According to the Book of Sui, on the one hand, Yang Jian sent his cronies to "secretly investigate hundreds of officials" and severely punished the corrupt behaviors discovered, and once dismissed more than 200 corrupt officials and corrupt officials in 52 prefectures of Hebei; On the other hand, Yang Jian often took the initiative to send people to "fish" against corrupt officials to enforce the law, that is, to send people to secretly want officials to offer bribes, and once they accepted bribes, they were immediately arrested and severely punished.
Different from the "fishing" law enforcement of Emperor Wen of Sui Emperor Yang Jian, the Tang Dynasty, which established on behalf of the Sui Dynasty, paid more attention to ordinary supervision, especially during the period of Li Shimin, Taizong of the Tang Dynasty, and established a complete supervision organization throughout the country. In the eighth year of Zhenguan, Li Jing, Yang Gongren, Wang Gui, and others were dispatched to inspect the world for the history of customs, and later more than 20 inspection envoys were dispatched to attach the political achievements of the officials in various places, and the names of the local officials were recorded on the screen, and any political achievements and evil deeds were recorded under the name, so that rewards and punishments could be uniformly carried out. In the 20 years of Zhenguan, thousands of magistrates below the rank of assassin and county order were punished for their poor political performance, and while 7 people were executed, 20 people were promoted.
Interestingly, Li Shimin often does not "punish" those corrupt officials who take bribes, but "rewards". Whatever you are greedy for, you will be rewarded; If you are greedy, you will be rewarded. After the incident, Li Shimin summoned the civil and military officials above the fifth grade in Chang'an City to gather in the Jinluan Palace, and then reported the bribery situation of the eldest grandson Shunde in full view of everyone, and told everyone: "The eldest grandson Shunde accepted dozens of bribes, which shows that he lacks silk at home, so I will award him silk." Subsequently, Li Shimin really asked someone to bring a lot of silk and satin, all of which were pressed on the back of the eldest grandson Shunde, and asked him to carry it back personally, almost crushing the eldest grandson Shunde to death.
Chen Wanfu, the general of the right guard, made a big deal of Sona card, and asked for a few stones of wheat bran from the post station, and Tang Taizong concocted it in the same way, and also gave him a reward in this way, telling him to pick up a few stones of wheat bran from the court in front of everyone. Chen Wanfu was ashamed and embarrassed, and he couldn't wait to find a crack in the ground to get into. The effect achieved by such a means of curbing corruption is no less than that of a thunderbolt method of killing people and arresting people at every turn; therefore, during Li Shimin's reign, the corrupt elements were greatly restrained, and he created the famous Zhenguan rule in the history of the mainland, which was praised by the people.
