Why do we keep learning history repeatedly?

From a romantic point of view, history is a memory. Some things exist in people's minds, and we need to constantly recall them. Studying history is to think about the successes and failures buried in rolling waves and yellow sand, which is of course dull, and then we will cherish the present. From a rational point of view, history can only be used as a reference, and we can never fully accept it, because history is written by heroes. We study history to cultivate a kind of worship for some people, which is what heroes demand of us. ................ Well, I prefer history. I think there must be a thousand-year secret buried under the skin of that yellow book.
