The original purpose of history
The original purpose of history is to learn lessons and sum up experience for future generations.
The practical guiding significance of history
History is very complicated and has practical guiding significance. For example, if we study the history of War of Resistance against Japanese Aggression, we can think about why the Japanese invaded China. Why did China win? The ultimate goal is to prevent the Japanese from invading China again. Or win again when China invades.
The influence of history
Our attitude towards history will determine our future. The past history will affect the present. For example, the Russian "October Revolution" and the establishment of the Soviet Union had a great influence on China. With the development of history, this incident has deeply affected your life and mine.
Read more extracurricular history books.
The school history books are not important at all. All are exam-oriented education. If you want to learn history well, you should read more extracurricular history books. For example, regarding the Opium War, don't just read textbooks and think that textbooks must be correct. We should not only look at the history written by the Chinese, but also look at the history written by the British, thus generating our own understanding of history. That is my own opinion.
Look at the historical special blocks.
Telling historical stories is a good way. But I think it's just for children, hehe. At present, all major online forums basically have special seats on history. Reading these is definitely more meaningful than reading rigid textbooks, and you can learn a lot.
