In the Eastern Jin Dynasty, the Northern Expedition commanded by Xie An was originally very successful, advancing the northern territory of the Eastern Jin Dynasty to the area south of the Yellow River, but, after Huan Wen, Sima Daozi, who ruled the imperial court, tabooed Xie's high merits, and the court discussed "to conscript for a long time, it is advisable to return to the army", so that Xie Xuan returned to the town of Huaiyin, and finally the Northern Expedition failed.

Ay! Ay! Ay! What a damn intrigue!

could have taken advantage of the chaos in the north after Fu Jian's death to take the opportunity to regain his hometown, but ...... Although there is a pity, it is only a pity for Xie An's father and son, the Jin Dynasty was already eroded when it was in the Western Jin Dynasty, and it is really amazing that it can survive for so long when it runs to the south.

It has been mentioned many times before that the prosperity of the scholars in the Jin Dynasty was prosperous enough to influence the imperial power, but the scholars liked the Qing officials who were "idle and heavy" and close to the emperor's Qing important positions, and looked down on the turbid officials with low status and tedious affairs, in fact, compared with the Qing officials, the turbid officials had more real power, which is probably the reason why the founding emperors of the four dynasties of the Southern Dynasties were all Han people.

In the later period of the Eastern Jin Dynasty, the scholars became even more extravagant, and developed to the extent that "when you go out, you will take a car, and when you go home, someone will support and serve, and no one will ride a horse in the whole town".

This phenomenon persisted throughout the Southern Dynasties.

The scholars looked down on the Han people, even the founding emperor and the imperial family, they were still ridiculed by them, and it was not until the Sui and Tang dynasties that the imperial examination system developed from the "Nine Grades Zhongzheng System" appeared, and the scholars and gate valve politics completely disappeared.

Lu Simian pointed out that the demise of the scholars was not entirely because of the Jiupin Zhongzheng system, but because the livelihood of the scholars was becoming more and more embarrassing, so the number of scholars and Shu people who communicated and intermarried gradually increased.

Prior to this, the scholars did not intermarry with the Shu people, let alone the general spectrum, and the result of intermarriage and general spectrum was that the "scholar clan" class became less and less obvious, and the imperial examination system was probably the last straw that crushed the camel.

At that time, when migrating to the south, there were those who led the relatives of the clan party to travel together, and there were also local wealthy families who called friends to go together, so the number of households in each migratory army was as large as thousands, and they gave each other help and beneficial, and established discipline.

You can imagine what a spectacular scene it was, and if you don't look at each other, I'm afraid it will have to stretch for several kilometers.

After the northern tribes moved south, they occupied fertile land, demarcated areas and forbade mountains, and hid the population.

It is no wonder that the north and the south are incompatible, and they thought it was only for political reasons, but in this way, I am afraid that in the eyes of the southerners at that time, it was not people who migrated from the north, but locusts.

Power will disappear when it is easy to move to another place, so those who were able to gain a foothold in the south at that time were actually people who were in power at that time, and the rest were becoming more and more embarrassed.

Later, the imperial court implemented the land division (the Eastern Jin Dynasty and the Southern Dynasties implemented a policy of sorting out household registration and adjusting local administrative divisions in order to solve the problem of overseas Chinese), so that the relationship between the expatriates and the locals became closer and closer, and the prejudices and other estrangements caused by regional and custom reasons gradually dissipated.

The scholar class has disappeared, but the atmosphere of the scholar culture has remained in the Chinese culture.

For example, the pursuit of ethereal gorgeousness and gorgeousness.

The "metaphysics" that was brought to the south by the southward migration was also reduced to the pursuit of beauty during the Northern and Southern Dynasties, and the simple pursuit of rhetorical ornificence, regardless of its essence, became a means of entering the official ranks.

"Metaphysics" has changed from the ice and jade of the Wei and Jin dynasties to a filthy appearance, and the contradictions between various strata have become more acute.

At this time, someone needs to come out to end this erosion, at least first the political erosion.

In 420, Liu Yu appeared! In fact, he has already appeared.

Do you remember Liu Yu? It is to raise troops with the generals and drive Huan Wen's son Huan Xuan out of Jiankang's generals. He took advantage of the chaos to replace the Jin and establish the "Song" dynasty, known as the Liu Song dynasty in history, which was the first dynasty of the Southern Dynasty.

The Jin Dynasty was completely destroyed, and the south entered the Southern Dynasty period of the "Northern and Southern Dynasties".

The responsibility for the decline of the Jin Dynasty is not on Jia Nanfeng, nor on Emperor Sima Zhen of Jin Hui, but on Sima Yan, Emperor Wu of Jin, who established the Western Jin Dynasty.

Lu Simian's evaluation of Sima Yan is: Involved in troubled times with Sinoma.

What does Sinoma mean? Medium talent. If it is an era of peace, it is okay for Sinoma to be the emperor, but Sima Yan is in a troubled era.

It was not Sima Yi and Sima Zhao who replaced Cao Wei to establish the Jin State, but Sima Yan, although without the foreshadowing of Sima Yi and Sima Zhao, Sima Yan could not replace Cao Wei, but Sima Yan had to face many problems in the change of dynasties.

Sima Yan implemented some decrees, such as:

Admonish the county officials, ministers, and commanders: We must do our best to adapt measures to local conditions, and prohibit those who eat without work and vendors; Let the ministers inside and outside exalt the upright and capable people, and promote the poor people. After that, he repeatedly promoted talents, and tried to increase the income of officials, because he wanted to put an end to corruption.

After the pacification of Wu, he immediately set the household to adjust the style, dismissed the military service, and went to the state and county soldiers.

It also looks like it's making a difference.

However, the top priority at this time is not legislation, but administration; It is not the frequency of the documents used to issue orders, but the severity of the supervision, but unfortunately, Sima Yan did not grasp the point.

Sima Yan did not treat those who should be treated leniently, and did not severely punish those who should be severely punished, and the disadvantages of doing so were very great.

For example, although a ban on luxury was promulgated, when Sima Yan was building the Taimiao, he went to Jingzhou to get wood, went to Huashan to quarry, cast twelve copper pillars, and painted them with gold, carved them with hundreds of things, and decorated them with pearls.

Sima Yan went to Wang Ji's house for dinner, and the food on the table was very rich.

It is conceivable that in ancient times, when transportation was inconvenient and materials were scarce, the meals were deliberately mentioned, which can be seen that they were all ingredients that were not easy to obtain or scarce under the conditions of the time.

And these foods, all served in glass vessels, one of the steamed pigs - maybe steamed suckling pig - is very delicious, Sima Yan asked how to cook, Wang Ji said that it was steamed with human milk, Sima Yan was displeased, and left the table before eating.

However, Sima Yan did not punish Wang Ji afterwards.

At that time, the nobles Wang Kai, Yang Xiu, Jia Mi, the heroes He Zeng, Zeng Zishao, Shi Chong, Ren Kai, Yu Yu, He Qiao, and Wang Jun were all extremely extravagant.

The prohibition of extravagance became an ornament.

Fu Xian was at the beginning of Xianning (Xianning: 275 ~ April 280, the second era name during Sima Yan's reign), and once wrote:

"In ancient times, Yao lived in a thatched house, but now, people are vying to decorate their houses. In ancient times, courtiers did not have good food, but now, even merchants are tired of exquisite food. In ancient times, queens and concubines had special costumes, and today, concubines and maidservants wear ayaluo. In ancient times, doctors and above did not walk, but now, the lowly officials have become fat because of the ride. ”
