Just anecdotally, every Chinese from China I've ever met has an obsession with how great China is. They always refer to ancient history. I'm pretty sure the communist party is coopting their history and cultural to create some sort of civilizational euphoria for the people, to achieve their goals. It really can't end well. It's funny because Americans will say America is the best country on earth, but they don't actually 100% mean it, like they know other places aren't bad too.
