make a clear distinction between right and wrong
First of all, you should love history.
Love people in history
You can read biographical novels appropriately.
Do you know what happened before
Take everything that happened in history as a story, and the most important thing is to cultivate your own interest. It's important to learn by rote, but we still need to know the reasons and effects.
Remember that the most important thing is to cultivate your interest.
I suggest you read those biographies first.
For example, The Romance of the Three Kingdoms by Yang Jiajiang and The Legend of Heroes by Sui and Tang Dynasties are both novels, and then you can see how the official history is different from these.
Understand the differences in turn.
Slowly, I think you will like history.
