Legal analysis: According to relevant laws, primary and secondary school students are not allowed to bring personal mobile phones into campus in principle, and schools are not allowed to use mobile phones to assign homework. The original intention of banning mobile phones from entering the campus is naturally conducive to students' concentration on their studies and improving the classroom effect. Strict management of the use of mobile phones on campus can effectively prevent students from indulging in internet and games, but banning mobile phones is not the purpose. More importantly, it is to cultivate students' self-discipline ability and teach students to use mobile phones in a standardized way.

Legal basis: Article 33 of the Regulations on the Protection of Minors' Schools may prohibit students from bringing smart terminal products such as mobile phones into schools or using them on campus; What is allowed to be brought in should be managed in a unified way, and it is forbidden to be brought into the classroom except for teaching needs.
