There are two main points: 1. Take history as a mirror to guide the future, 2. Enhance national self-esteem and self-confidence; From the perspective of the beneficiaries of history, it can be divided into micro and macro levels, one is the role of history on individuals and enterprises, and the other is the role of history on the country.

History, for short, refers to the history of human society. It is a discipline that records and explains a series of historical events in the process of human activities, and it is also a mapping of the present era in many cases. If it is only summary and mapping, then history as an existence should disappear. The problem of history is to discover the real past constantly, to speak with materials, and how people can become a negotiable problem in reality. History is an extension. History is the inheritance, accumulation and expansion of culture and the track of human civilization.
