Shit goes back over a thousand years.
Northern Commies vs Southern Nationalists in Chinese civil war.
Northern and Southern dynasties after the collapse of Jin.
An Lushan rebellion where a Northerner rebelled.
Taiping rebellion which started in the south and remained in the south, unable to breach into the north.
Song Dynasty vs Jurchens, south vs north.
Red Turban rebellion where Ming emerged in the South.
Wu + Shu against Northern Cao Wei.
Just off the top of my head, im sure theres a fuck ton more.

Realistically speaking, could Wanli Emperor actually prevent the fall of ming?
>silver shortage due to european wars leading to liquidity crisis
>little ice age leading to famines throughout the empire, wheat died and snow on rice destroyed the paddy fields
>droughts leading to famines throughout the area and entire grand canal drying up
>factional infighting within the imperial court between rich bureaucrats and eunuchs
>banditry rampant in famine stricken regions
>peasant rebellions
>smallpox epidemic
>manchurian invasion to the north
All of that shit happened at the same time and parents were eating their children to survive.
