“Dare to struggle and be good at fighting” is an important conclusion put forward in the report of the 20th National Congress of the Communist Party of China. Integrating this idea into the teaching of “principle course” is not only the inevitable requirement of the course nature, but also the due meaning of ideological and political course teachers. In the classroom teaching, we should focus on the four dimensions of philosophy, scientific connotation, time background and contemporary value, so as to realize the goal of publicizing the spirit of the Party’s Twenty National Congress report and improving the classroom teaching effect.
