To study history, we should strive to respect objectivity, and we need empathy, instead of just laughing at the past from the standpoint of the present. To learn history, we also need to have the ideological height of today's people and be good at discovering the limitations of historical figures and events in the past, otherwise we will become "historical prisoners" who know nothing about the past. Mr. Qian Mu once said that China people only pay attention to the accumulation of historical materials while ignoring the development of historical spirit.

To study history is to make a comprehensive comparison of politics, economy, culture, law, humanities and other aspects of each dynasty, so as to know which people and things conform to the historical trend and which behaviors are contrary to common sense; Then explore the laws of history and find the causal relationship of history; To look at a problem by substitution means to look at it from a certain angle, substitute it into the political and economic environment, way of thinking and interest disputes at that time, and solve social problems from the perspective of historical materialism.

We can let the children sort out the dynasties and memorize all the time points, from Xia, Shang and Zhou Dynasties to Song, Yuan, Ming and Qing Dynasties, to 2 1 century. Then remember the economic, political and cultural characteristics of each dynasty. Remember economy first, economy will affect politics and culture, so you can basically know politics and culture if you master the characteristics of economy.
