1. Learn some historical theories and know some methods and skills to study history. For the study of history, it is essential to study historical theory. Through the study of historical research methods and theories, we can master certain historical research skills and methods, thus accelerating the improvement of historical research ability;
2. Read more historical materials and try to master the comprehensiveness and accuracy of the historical materials you have learned. Historical materials were processed by predecessors. Due to the constraints of the historical environment, class position, value orientation and personal preferences of the people who collate historical materials, the written historical materials may not be true and comprehensive, so the understanding of historical materials needs to be comprehensive. Pay attention to the following aspects when reading:
(1) Pay attention to reading historical materials of different periods. The historical materials recorded in the period of historical events may be comprehensive, but the processing may not be strong. Although the historical materials compiled by later generations are highly organized, due to the age, the historical materials compiled may not be complete enough, or even bent to reflect the history at that time;
(2) Pay attention to reading different descriptions of the same historical event and hostile parties. The description and evaluation of the same historical event will be very different because of the different interests and values of the opposing parties. Therefore, only by reading the historical materials of the opposing parties and even the neutrals can we fully grasp the authenticity of historical events;
(3) Pay attention to reading the official history and unofficial history's books, so as to achieve the purpose of mutual confirmation. The mutual confirmation between the official history and unofficial history is indispensable, especially when Confucius in ancient China put forward "the taboo of saints, the taboo of relatives and the taboo of saints". Therefore, the accounts of rulers, sages and relatives can't be complete and comprehensive, and it is necessary to study a lot of unofficial history and official history to confirm each other.
3, the study of history should pay attention to the study of historical sites and cultural relics. Due to the subjectivity of artificial processing, historical materials need to be verified with historical relics and historical sites in order to get a comprehensive and true history. At the same time, combined with the study of historical relics and historical sites, we can draw correct conclusions and constantly improve the correct and comprehensive history;
4. After studying history to a certain extent, we should be good at thinking and adopt the general law of historical development to solve the problems existing in practice. For example, Marx and Enkesi studied the history of primitive society, slave society, feudal society and capitalist society, and boldly put forward that the next step of human history will enter the communist society.
