Why?
These four dynasties don't seem to have any inevitable connection.
They are also separated by multiple dynasties.
Why is their history relatively "normal."
"Uh, is there a possibility that these dynasties, which suffered less erosion, were more prosperous at the time?"
Eh?
It seems like that, doesn't it?
Could it be that the more powerful a country's national strength, the less eroded its civilization becomes?
But that's not right either...
First of all, if we're just talking about national strength, the dynasties closer to modern times are stronger.
Because initially, there were only short swords and spears; later came long-range attacks with bows and arrows, and around eight hundred years ago, there were firearms and cannons, long-range lethal weapons.
Secondly...
What use is the national strength from before?
The Qing dynasty was lost, huh!
