After the paper is finalized, in order to ensure the accuracy and completeness of the paper, it is usually not recommended to modify the submitted paper. However, if necessary, there are still some situations that can be modified: First, if the journal or conference you submitted allows you to edit, you can use this option to modify it. In this case, you need to contact the editing department to see if you accept the change and know the details and deadline of the change.

Finally, if you find any major mistakes or omissions in the paper, such as errors in experimental data, conclusions or methods, you should contact your tutor or reviewer in time to seek their guidance and suggestions. If revision is needed, you should follow the regulations of journals or conferences and submit a clear and detailed revision opinion.

In a word, it needs to be extremely cautious to revise the paper after it is finalized. For the sake of academic ethics and professional ethics, we should ensure that revision is necessary and comply with the requirements of peer review procedures and journals.
