After the social practice, the school will organize a defense. The basis of this defense is the social practice report you submitted. In the practice report, there are written explanations and answers to the topics, methods, practice process, gains, difficulties and problems of practice, so the teacher will conduct in-depth research and discussion on you according to these problems in your practice report. Then I really need to combine my own practical experience and make some valuable and meaningful conclusions, so as to cope with the teacher's questions and answers.
