First, it is unfair to other students. American universities take the issue of love between teachers and students very seriously and strictly oppose it. The love between teachers and students is not allowed, and the rules and regulations are sound. Teachers have extensive rights. They can evaluate students' work, write letters of recommendation, and act as mentors and consultants. The teaching of student teachers has great distribution rights. If teachers and students fall in love, teachers are likely to use power relations to seek convenience for their other half, resulting in unfair educational environment and unfair to other students.

The second reason: the client will be hurt, and the teacher will have a good impression, so the student's identity will be unconsciously misunderstood, which will affect the interpersonal relationship, communication and normal activities of the client at school, which is very unfavorable to the experience of campus life. When his other half is a teacher, sometimes it just happens that he needs to learn this course, it will produce different emotional factors, which will probably affect the teacher's teaching, hinder the students' learning attitude and be detrimental to the efficiency of teaching and learning.

The third reason: the influence on the educational authority. For the school, the love between teachers and students will lead to all kinds of gossip, and the fourth will lead to unfair education, which will lead to the rise of students' behavior towards the school and their distrust of the majesty and system of the school. Moreover, problems will cause great public opinion, which will easily damage the majesty and reputation of the school, affect the future development of the school, and easily damage the professional ethics construction of the school.

Reason 4: There is a certain interest relationship between teachers and students with incorrect identities, so if teachers and students become true love, there will be some fallacies in the responsibility between teachers and students. Teachers may not be able to carry out education and teaching activities correctly because of this affection, and students will also be unable to face up to their student status in this relationship. The identities of the two sides cancel each other out and collide with each other. In a way, this identity is not equal.
