In 2017, the opinions on strengthening and improving ideological and political work in Colleges and universities issued by the CPC Central Committee and the State Council clearly proposed to “strengthen humanistic care and psychological counseling, and promote the healthy development of College Students’ body, mind and personality”. The party and the state attach great importance to College students’ mental health education. College Students’ mental health education is one of the important work of Ideological and political education in Colleges and universities. It should also be the scope of the role and function of College Ideological and political teachers. The role and function of psychological counselors as educators, demonstrators and researchers bring enlightenment to college ideological and political teachers in Ideological and political teaching and college students’ mental health education. College counselors can actively learn from the role of psychological counselors from three aspects: learning from educational methods, participating in educational practice and exchanging teaching experience, so as to enhance the effectiveness of Ideological and political theory education in Colleges and universities.
