This paper analyzes the teaching metaphor of pre-service international Chinese teachers and explores the characteristics of transformative learning based on teaching beliefs. The findings indicate that most of the respondents' teaching beliefs have been transformed after one semester of course study. The result of the transformation presents a humanistic tendency, and the process is imbued with emotions. The enlightenment of the research lies in that metaphor is an effective way to promote the critical reflection of pre-service international Chinese teachers. We should pay full attention to and make effective use of their previous experiences. It is necessary to explore in-depth learning contents and methods in the training.
