This thesis summarizes the author's experiences in the course of the first class session of the Chinese language class-from the design of classroom mode to the implementation of this activity by students. After the activity, a questionnaire survey was conducted and the survey results were analyzed and summarized. Through the questionnaire, the author analyzed students’ satisfaction degree of “one-day teacher” activity. The questionnaire survey was conducted from several perspectives, including satisfaction, learning effect, self attitude towards this “one-day teacher” activity and what needs to be improved. The results were, to say the least, encouraging. From all aspects of the good evaluation. We can judge that the implementation of this “one-day teacher” activity in the Chinese language class is completely feasible. Although the feasibility of “one-day teacher” activity has been proved, how to better apply it in Chinese class is the next problem that needs to be improved and further studied. The object of this study is the Chinese learners at the intermediate level in the lower grade. How to carry out this activity for learners at different Chinese level? A series of problems will be further studied and discussed.
