To study the "Four History", we should adhere to the guidance of the grand historical view, fully activate the broad vision of thinking for a thousand years and seeing Wan Li, put the 40-year history of reform and opening up in the background of the 70-year history of New China, the 70-year history of New China in the course of the party's hundred-year struggle and the 100-year history of the party in the 500-year history of socialism.

The study and education of "Four History" can not be satisfied with the understanding and mastery of general historical facts, but should persist in treating the history of the Party, the history of New China, the history of reform and opening up and the development of socialism as a whole, be good at breaking through the appearance of history, go deep into the core of historical events, be brave in exploring the deep-seated reasons behind major historical events, and profoundly interpret the mental journey of important historical figures at the turning point of history.

The core significance of studying "four histories" is historical facts, historical views and historical lessons.

Historical facts, that is, to find out the objective past; Historical view, that is, our understanding, explanation and evaluation of the past; Taking history as a mirror means taking history as a mirror, serving the reality and enlightening the future. These three elements are interrelated. Historical facts are the cornerstone of understanding, explaining and understanding history. We say that "there is nothing in words, and there is evidence in history", which means that history learning should proceed from facts.

Historical facts depend on historical materials, but historical materials are not equal to historical facts. Only by removing the rough and selecting the fine, discarding the false and retaining the true, can historical information approach "nature" step by step.
