It is very normal for China to change dynasties in history, but most dynasties ruled by loyal monarch. After all, the emperor of the feudal dynasty is the supreme power, and what he needs most is the loyalty of civil servants and military commanders. But in many dynasties, there is one exception, that is, the Jin Dynasty. Since the founding of the People's Republic of China, the Jin Dynasty declared that filial piety ruled the world. What happened?

As we all know, the ancients were deeply influenced by the thought of three cardinal guides and five permanent members. Generally speaking, the king of a country cannot dispose of it at will, even if it is the king of the country.

So Qin destroyed the six countries, but did not kill the six monarchs. Xelloss also forced Emperor Xian of Han to abdicate, and let him go without killing him. But since Sima Shi, after the change of Gao Pingling, he not only broke his promise and killed Cao Shuang and his clan who surrendered, but also instructed Ji Cheng to kill Di Wei. This kind of kingslaying behavior is despised by later generations.

Relatively speaking, Liu Bei trusted Zhuge Liang, who not only devoted himself to Shu Han, but also his son Zhuge Zhan died in the battle of Shu Han. This is true loyalty.

In contrast, Wei, Cao Rui trusted Sima Yi, who not only didn't want to serve the country, but launched the change of Gao Pingling to control Wei's military and political power. His son Si Mazhao abolished the emperor regicide, and his grandson Sima Yan forced the Wei Yuan emperor Cao Huan to abdicate. It can be said that Sima Yi has no "loyalty" as a courtier. Sima clan is still disloyal, so it is not good to govern the country with "loyalty".

Since it is impossible to rule the world with loyalty, the rulers had to give up the education of loyalty to the monarch and patriotism and turn to rule the world with filial piety. After all, there is no distinction between loyalty and filial piety. Because of the advocacy of the court, there were indeed many dutiful sons in the Jin Dynasty.

Wang Xiang, a senior official in the period of Emperor Wu of Jin Dynasty, was one of the "Twenty-four Filial Pieties". The Jin Dynasty was unfilial and offended more than rebelled. Those who conspired could be released by amnesty, but those who were unfilial would not be released anyway.

. However, the emphasis on filial piety ignores the emphasis on loyalty, or is forced. The Jin Dynasty originally wanted to integrate loyalty and filial piety, but history proved that many loyal ministers were unfilial and many dutiful sons were unfaithful.

In fact, filial piety is not the real filial piety that rules the Sima family in the world. In the Eight Kings Rebellion, brothers killed each other and grandparents killed each other, which is the biggest mockery of "ruling the world with filial piety". The Sima dynasty died in just a few generations, and the Jin dynasty became one of the few dynasties with poor evaluation in history.
