The cultivation of teachers' morality is the core of prospective teachers' education. It has important practical value for deeply implementing the fundamental task of Li De Shu Ren, meeting the construction of teachers in the new era, and cultivating teachers with noble moral sentiments. At present, in the process of cultivating teachers' morality, prospective teachers are faced with multiple dilemmas, such as the impact of multicultural values, the binary opposition between heteronomy and self‐discipline, the separation of knowledge and practice in teachers' morality cultivation education, and the solidification of the evaluation model of teachers' morality cultivation. To break through these dilemmas, it is necessary to take socialist core values as the guidance and guide the cultivation of normal university students' ethics. Internalize the moral quality of normal university students with the main line of teacher's ethics construction; Take teacher's moral growth as the cultivation path to improve the teacher's moral level of normal university students; We will promote the cultivation of professional ethics among normal university students on the basis of diversified professional ethics evaluation.
