#Ming general #WuSangui betrayed the #MingDynasty & opened the #GreatWallOfChina gates at #ShanhaiguanPass — a strategic choke-point against invasion — on #ThisDayInHistory in 1644. Wu later betrayed the new #Manchu #QingDynasty as well, as the self-interested cannot be trusted.

What many call "#Qing" (giving the erroneous impression that #Chinese controlled #Taiwan 🇳🇫) should actually be called "#Manchu" as the #Han_Chinese considered the Manchus to be "foreign invaders."
