How to deal with the high incidence of sexual assault in colleges and universities? First of all, for colleges and universities, teachers' morality should be improved in capital construction. In terms of management and control system, it is necessary to further independently innovate the reporting methods, unblock the safe reporting channels, immediately track and feedback the case clues, make the supervision tentacles more alert, and give reasonable application to the victims when necessary. In any case, colleges and universities should be areas where school leaders and teachers show students the natural environment and service platform for learning and training professional knowledge, shaping professional skills and shaping personality traits, and should be a paradise for students, not a prison full of desires, scandals and oppression.
