Although college students have grown up, their world outlook, outlook on life and values are still in the critical period of formation, and their minds are not yet fully mature, so the love between teachers and students can hardly be said to be pure love. What is important is that the roles between teachers and students in colleges and universities are not equal, and there is a relationship of management, power and interests. Even if the relationship between teachers and students is purely emotional, this relationship will undermine fair competition and is not in line with the principle of interest avoidance in the modern university system. Therefore, there are also many universities that explicitly prohibit the love between teachers and students.
