In spite of the extremely high temperature, paper evaluation of College Entrance Examination is in order in Hubei province. Two security guards stand at the entrance of the building where teachers are marking papers. Your cell phone signal will be blocked if you come near the building, because there are several mobile phone signal jammers set in the building.

         The paper evaluation is done through computer. If you walk in one marking room, you can see dozens of teachers focus on the computer screen in front of them and mark papers quietly. There are cameras in the marking rooms and the hallway to supervise teachers in case of cheating. Before the official papers evaluation, teachers established rules of evaluation and organized a testing evaluation to solve problems and find the general condition of students answering papers.

         All the marking rooms are influence d by mobile phone jammer, and teachers must enter the room with certification and have to be examined before. These rules are made to ensure the security of evaluation.
