The history of China going back millennia is chock full of violent revolutions and civil wars. They don't seem to learn anything from mistakes. I fully expect another one in our lifetimes.

You should look at European history for comparison. I don't remember, what did they have, a 100 or 200-year war?

Yes, Europeans are equally unable to learn from their mistakes.

You should grasp that China has maintained a civilization through line for 5K years. No other state comes close. The question is how.

Civilization has been maintained in other places such as Egypt for just as long. You can argue about the degree of continuity but the modern nation state of China bears almost no resemblance to what existed on the same territory 5K years ago. So I don't understand what point you're trying to make.

What does that even mean and how does it compare to any other place that is inhabited by humans?
