Abstract: The key to running the ideological and political theory course well lies in teachers, and the key to enhancing the affinity of Ideological and political theory course also lies in teachers. The teachers' discourse affinity in ideological and political theory course is an important medium to highlight knowledge, thought and truth. Its connotation is embodied in the "human" of charm, the "art" of educating people and the "Tao" of being a teacher, which contains three theoretical horizons:discourse understanding from the perspective of philosophical hermeneutics, discourse acceptance from the perspective of reception theory and discourse characteristics from the perspective of humanism. These three discourse perspectives point out three ways to forge the teachers' discourse affinity in ideological and political theory course:improving the discourse understanding effect of teachers with dialogue "interaction", improving the discourse acceptance effect with innovative "demand", and realizing the discourse empowerment of teachers with creative "supply".
