Can a postgraduate teacher communicate with the outside world?

Teachers who give questions in the postgraduate entrance examination cannot communicate with the outside world. Before the exam, the education discipline inspection and supervision department should manage the proposition teachers, and it is strictly forbidden for proposition teachers to participate in postgraduate training and personal counseling. Focus on checking whether the re-examination staff implements the avoidance policy to ensure that the tutor and examiner do not contact the candidates alone before the re-examination. Conditional enrollment units should video the whole process of re-examination, and draw lots on the spot to determine the re-examination examiner.
