Someone sent a text message threatening my sister, who is still a high school student. Is it useful to call the police?

Is there a mental health teacher in middle school? Middle school is better than university, and teachers can hold on if they want to talk to students. Why not go directly to the class teacher? Because this passerby is often a poor student, I am afraid that I have been deadlocked with the class teacher and won't listen.

In fact, the society ruled by law also has great defects. Don't listen to Mei people saying that we rule by man, but we can't reach the rule of law, so we just feel soft and think the rule of law is good.

The law can control the hands and feet, but it can't control the heart.
