But what the Cho Dynasty explains is that this is a cycle that doesn't last forever. Now first you're going to have the mandate of heaven obviously give power to the Cho because they're the most powerful and the wise. But with that mandate of heaven comes a responsibility. And like in most cases, when you're in power a long time, you're going to see corruption. And the cyclical nature of the mandate of heaven says that eventually when that corruption comes you're going to have revolt. You're going to have the gods putting down natural disasters. You're going to have invasions because you're not doing the right thing.
