One of the reasons for rebellious psychology is that teenagers are in a transitional period, and their sense of independence and self-awareness is increasing day by day, hoping to get rid of the guardianship and bondage of adults. They are against adults who regard themselves as children and pretend to be adults. In order to show their uniqueness, they tend to find fault with everything. When they feel or worry that the outside world ignores their independent existence and their desire for self-expression is hindered, they will have rebellious psychology and use various methods and means to establish their feelings of opposition to the outside world. Second, social factors, such as improper educational methods of teachers' parents. Rebellious psychology will lead to teenagers' suspicious, paranoid, indifferent, unsociable and other pathological characters, which will make them shake their beliefs, lose their ideals, decline their will, be passive in work and study, and lead a depressed life. Further development may also be transformed into criminal psychology and morbid psychology.
