Conducting the content infiltration of positive mental health education in Chinese teaching is not only the requirement of positive mental health education, but also the requirement of Chinese subject teaching itself. On the basis of summarizing the practical teaching experience, this paper summarizes four methods to conduct the content infiltration of positive mental health education in Chinese teaching, that is: constructing mainstream stories to promote positive identification; bringing students into situation to inspire introspection; reshaping students’ positive mind to promote application; arranging writing exercise to promote students’ comprehension.
