Whether the paper can be revised after blind review depends on the specific situation. Generally speaking, if the paper is found to have major problems or serious defects in the process of blind evaluation and needs to be revised, it needs to be revised after blind evaluation. This revision may be a comprehensive revision of the overall structure, research methods, data analysis and interpretation of the paper.

In addition, if only some minor amendments or suggestions are put forward in the blind review process, and these opinions or suggestions do not need major amendments, then appropriate adjustments and amendments can be made according to these opinions or suggestions after the blind review to improve the quality and level of the paper.

In short, whether the paper can be revised after blind review depends on the specific situation.
