According to the law, this is illegal. Teachers have no right to search students' bodies. This is a violation of human rights. They dare to search the suitcase, dare to pry it open with a lock, and dare to search schoolbags and lockers in class. Such a teacher is incompetent and doesn't even understand the most basic laws and regulations. How can they be teachers? If there is such a thing, students can call the police directly. Students need not worry too much. Some parents have the concern of the masses, and I believe you will give me justice.
