Just like after Sima usurped Wei, with a sentence of "Fuxi Holy Dynasty ruling the world with filial piety," it led to the embarrassment and disgrace of Western Jin.
It is important to know that before Jin, all dynasties ruled the country with loyalty and filial piety, even Cao Wei was no exception.
Yan Wangqiu, who stole the throne of the country, established the Nanhai Country just like the Western Jin, it naturally lacked a layer of moral justice, had no righteousness, and was ridiculed by the people of the world, unable to really win people's hearts and recognition.
The political situation in the Nanhai Country was also the same.
The officials were corrupt, the governance was rotten, and the common people were not even as good as pigs and dogs.
Lacking the justice and reason of the Yan lineage, in order to maintain their rule, they had to give up a lot of interests, to win over the powerful nobles within the country who held real power, in exchange for their support.
