First of all, historical talents are the ability to master historical materials, describe historical facts and write articles. The past and time sequence of history determine that history teaching has strong personality characteristics, which requires history teachers to have strong language expression ability. The language expression ability of history teachers directly affects students' absorption of historical knowledge and their enthusiasm for learning history, which is related to the teaching effect of teachers. Secondly, historiography is systematic, profound and solid historical knowledge. History teachers should study textbooks from the perspective of history subjects and historical monographs, so as to reach the peak, under one mountain and under ten thousand mountains. Instead of staying at the same shallow level as textbooks. It is necessary to know and understand the syllabus and teaching materials, sort out clues, and comprehensively grasp the knowledge framework of teaching materials. Only in this way can we condescend, learn from others, accumulate a lot of knowledge and explain it in simple terms, and simplify, systematize and integrate textbook knowledge in the teaching process. Finally, historical knowledge means certain political, educational and psychological theories. Teachers are not only imparting knowledge to students, but also shaping their ideological quality. History teaching should be guided by the correct theory, help students understand the laws of historical development, form the basic viewpoints of historical materialism, and initially learn to use these viewpoints to analyze and solve problems. As a qualified history teacher, we should first be familiar with the relevant principles of Marxist philosophy, political economy and scientific socialism, master the dialectical relationship between productive forces and relations of production, superstructure and economic foundation, principal contradiction and secondary contradiction, phenomenon and essence, quantitative change and qualitative change, and the basic viewpoints of historical materialism such as development view, religious view and national view, so as to be able to explain, analyze and evaluate historical figures and events with correct positions and viewpoints and integrate ideological education into history teaching.
