First, it plays an indispensable and unique role in promoting the development of humanities, social sciences, thinking sciences, management sciences and other disciplines other than humanities.
Because there is no continuous development of history itself, and there is no history to change the sequence, integration and positivity of time from general requirements to in-depth concrete reality, the exploration of historical connotation by all other disciplines lacks the coordinates on which to exist and establish, and also lacks the motivation to deepen this exploration.

Third, it can be used for reference, that is, it can provide historical experience and lessons for people's practical activities, so that people can learn from history and avoid repeating the mistakes of human history.
The famous historical work Zi Tong Zhi Jian provided a historical reference for Qin Shihuang.
Liang Qichao once praised this book as the most beneficial to people's minds.
Polybius, a famous ancient Greek historian, also made it clear in his book History: "As far as political life is concerned, the best education and training is to study history.
In view of the mistakes of predecessors, there is no other way to teach people how to face difficulties bravely and overcome their destiny. "
Fourth, it has educational functions, including moral education, ideal education and historical vision education.
Studying history plays a subtle role in improving people's humanistic quality, ideological realm, perfecting personality, cultivating sentiment, shaping a beautiful soul and learning to be a man.
From it, we can realize the pain and joy, frustration and victory of our ancestors in the process of pursuing their ideals and changing their destiny, and realize the meaning, value and dignity of life.
Fifth, it also has special entertainment function, leisure function and recreational function, that is, you can spend your leisure time by studying history, and you can get pleasure and aesthetic taste from it.
