There are three levels of historical perspectives in this world: The first level, the most basic, is the nationalist view of history, which judges history solely based on "us and them," with our nation always being correct, and evaluates figures and events primarily through stance and emotion; The second level is a human-centered view of history, which no longer focuses on ethnicity but on whether a regime brings stability to the people and whether society is developing, using people's livelihoods as the standard of evaluation; The third level is a more macro perspective, no longer focusing on specific individuals or moral judgments, but starting from overall structures and long-term patterns, believing that the rise and fall of history are more driven by large-scale factors such as population, resources, and productivity, with individuals and chance events being difficult to change the overall trend.
