Mainly because the Jin Dynasty's national and scientific comprehensive influence is very small, so the sense of existence is very low. Although there were some major events in the Jin Dynasty, most of them were negative, which caused the gloom of Sima Yi's three generations. In fact, after Sima Yi seized power, the Jin Dynasty also had a period of stability and relative economic prosperity, which was called the rule of Taikang in history. If we follow this opening, the Jin Dynasty will also be a good dynasty. Unfortunately, Sima Yi has no money, and Cao Cao is in urgent need. He himself is not immortal. After his death, the Hu people who had taken root in the north secretly sharpened their knives.

From Sima Yi, Sima Shi acted in Cao Cao's period, playing the fool, and gradually moved towards autocracy. When he arrived in Si Mazhao, although everyone knew it, he still acted. When he arrived at Sima Yan, he finally forced the little emperor of Cao Wei to give way. These three generations solemnly advocated ethics, but secretly plotted to usurp Cao Wei. When Sima Yan reached the top, he was a lecherous man.

There are more than three thousand beautiful women, ten times more than thirty thousand. Sima Yan's successor Sima Zhong is an idiot. She once asked a question throughout the ages. When people starved to death during the great famine, he even asked a fool why he didn't eat paella. The emperor is like this. How good can the social atmosphere in the Western Jin Dynasty be? At that time, the Six Peaks of the Western Jin Dynasty prevailed, with money worshipping maple, flattery, cronyism and singing to help the wind, so many talents left the court one after another, with a huge momentum and unwilling to serve the country.

The Jin Dynasty in history was divided into Western Jin Dynasty and Eastern Jin Dynasty. Although the total time was 150 years, the later Eastern Jin Dynasty was divided up and did not belong to a complete unified country. During this period, there were no famous emperors, and there were many straw bags. The reason why the three countries have a strong sense of existence is because there are too many talents, and the Jin Dynasty is a dynasty with a record of behavior, leaving no important historical materials, so it is unknown. After the Western Jin Dynasty, it was another situation in the May 4th period. Han people were invaded and plundered by the five lakes crazily, which was as cruel as Japan's invasion of China. Han people don't want to recall this history, because this history almost declined the Han culture. At that time, even the Han people in the south might have been killed by the conference semifinals if there were no orders to kill gods and deal with them in a timely manner. Therefore, the troubled Western Jin Dynasty is an absurd history of Sima's family and a disgrace to the Han people, which makes all historians reluctant to look back. In a word, people like to pass on a period of history because the rulers did something beneficial to the people during that period, while cruel, bloody and absurd societies are generally reluctant to publicize it, including the shame of Jingkang and the four-tier system of the Yuan Dynasty, which are among the few records. There is a reason why it is not a strong country without accidents, and the social atmosphere is poor and the sense of existence is low. ?
