Be careful when making friends. As the saying goes, "If you are near Zhu Zhechi, you will be black". Young people like making friends. If you have friends with bad morals and behaviors, you should cut off contact with them immediately.

Don't set foot in unhealthy places. Some public entertainment places, such as dance halls, discos, video halls, Internet cafes, etc., which are easy to shelter evil people from evil practices, have brought serious negative effects on teenagers' body and mind.

4. Psychological prevention. Teenagers are in the period of physical growth, immaturity and maturity, their physical and mental development has not yet been finalized, their cognitive ability is limited, and their emotions are strong and impulsive. Their behavior is often influenced by feelings or emotions, which often leads to the contradiction between reason and emotion. When individuals are angry, their understanding and self-control are obviously reduced, and they often make unexpected behaviors. Therefore, when students encounter problems, they should communicate with teachers, classmates and parents in time to jointly study ways to solve the problems, and don't go on the road of breaking the law and committing crimes on impulse.
