Recently, a netizen revealed that a university has installed cell phone jammer and mobile phone shielding bags in the classroom. The netizen expressed his dissatisfaction with the university and pointed out that such strengthening measures are not reasonable. On the afternoon of September 17, a reporter from the local daily learned from the school that the reason why the school installed the mobile phone signal blocking device in the classroom is to build the examination room for graduate students, and the purpose of setting the mobile phone shielding bag is to enhance the teaching construction and improve the classroom order and supervision.
