Under normal circumstances, non-confidential students should not write confidential papers, which may contain sensitive information of the country, enterprises or individuals and need to be kept confidential. Students should not touch or write confidential papers without the corresponding confidentiality review or approval.

Mainly because confidential papers need to be kept confidential, and confidentiality involves national security, social stability, personal privacy and other vital interests, and special confidentiality review and approval are needed to ensure that this information will not be leaked or abused. Non-confidential students will not be able to grasp the risks and handling methods of these sensitive information without relevant confidential knowledge and confidentiality approval, which will easily lead to security problems such as information leakage.
