The middle school period, although it only accounts for a few tenths of the long river of life, is an important stage of dramatic changes and rapid development of individual psychology. With the obvious and important physiological change-the emergence of the second sexual characteristic, sex tends to mature, while drastic psychological changes are often ignored by parents and even schools, either simply comforting and punishing children with language or taking children as role models for adults, seriously ignoring the psychological needs of students in this special period. Only a few students occasionally attract attention from all sides because of the appearance of extreme events, which is very passive and unscientific. It is necessary to nip in the bud, actively do a good job in mental health education, and guide students to produce psychological imbalance and physiological reasons of various conflicts in time.
