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. [1] History is an extension. History is the inheritance, accumulation and expansion of culture and the track of human civilization.
