Scholars and teachers expect the relationship between home and school to be "one master and one guest", but with the increase of parents' power, parents begin to play the role of critics, supervisors and even knowledge overlords. With the popularization of education, the educational level of parents of students has also improved, and parents began to question the authority of teachers, thus distrusting teachers psychologically. Based on this, inexperienced teachers will also have resistance to parents' opinions, which will lead to contradictions.

2. Conflicts caused by resource allocation

Resource allocation refers to class affairs and some arrangements related to students' interests, such as the adjustment of seats and the appointment of class Committee positions. The conflict caused by resource allocation mainly comes from the actual arrangement of teachers according to the class situation and the parents' doubts about fairness.

3. The conflict between exam-oriented education and quality education.

In the evaluation system of primary and secondary schools, the misconception that "everything is good if you learn well, and nothing is good if you learn poorly" is still widespread. Under the general environment that the country vigorously promotes quality education, schools provide students with all-round education in moral, intellectual, physical and aesthetic aspects. Some parents think that grades are the most important consideration. They blame the poor academic performance of their children on the school's educational methods and teachers' personal abilities, which leads to estrangement from teachers, expressing dissatisfaction with actions or words, and triggering conflicts between home and school.

4. Conflicts caused by school management defects

The defects of school management are mainly reflected in the lack of corresponding systems and norms in post exchange of school teachers, induction training of new teachers and evaluation of teachers' ability.
