The classmates who committed suicide all left suicide notes. In their notes, they all mentioned their parents forcing them to study, and at school, the teachers only cared about grades. If they improved, the teachers wouldn't notice.
But if they fell behind, the teachers at school would harshly criticize them, and after returning home, their parents would also scold them.
It was all extra tutoring, and they had no personal space at all.
Even writing a diary, their parents would stealthily read it.
During winter and summer vacations, if they occasionally wanted to hang out with classmates, their parents would demand they not fool around, warning that it would affect their grades, and question how they could get into a famous Chinese university in the future.
They couldn't bear such a life and in the end, they decided to commit suicide together.
Only by committing suicide together did they have the courage.
They weren't afraid anymore.
