Under the influence of various factors such as increasing employment pressure and fierce job competition, college students have become the mainstream of the times as successors and innovators of future socialist construction. This paper aims to study the penetration path of mental health education(MHE) in the campus cultural environment, and to improve the teaching quality of ideological and political theory courses in colleges and universities by organizing relevant courses in schools and conducting targeted consultation and management activities in combination with the current situation of students' career planning. This is of great significance for cultivating talents with all-round growth and high comprehensive quality. After that, this paper studies the career planning model of college students, and tests the basic functions of the model.
