First, understand memory. History is a subject to remember, and there are many things to remember. But if you just remember it, you must understand it. When you look at any historical event, you can't look at it one-sidedly, including what is in the textbook, which may not be right. You should use your ideas to understand it.
Second, history has a development process and framework. You must have a timetable, that is, the time when historical events occur. There must be a main line. Especially the history of China, is very readable. Every dynasty is like a cycle, established, powerful, weak and extinct.
Third, to learn history, we must learn to read a lot of extracurricular books and watch more historical TV programs to enrich our historical knowledge and understanding. In fact, some history on TV may be wrong, which doesn't matter. You will correct it later. Watching TV can at least familiarize people with logistics.
Fourth, a little more advanced. With the growth of age and different social experiences, people will have different views on history. So don't go into a dead end, historical events are not absolute.
Fifth, learning history means learning from history and finding the law of social development from historical events. Not just for exams. Learning to think about history will make you smarter. If you just recite textbooks and cope with exams, you will be confused and at a loss.
