But why should we look at history? Because to some extent, history can be repeated. It can be said that history can make people wise. True history is often murdered when the outcome has been decided. We don't need to point to the real history at all, but if you study history, you can see the flaws in small places.
We study history mainly to learn knowledge and make ourselves knowledgeable. Different people may have different translations of a sentence in classical Chinese. The history you read may be true in itself, because it makes you suspicious and gives you an impulse to know your body and mind. Then, over time, you will know a lot.
