It is quite common to reject the manuscript again after revision. The revision of the paper itself is a repetitive process, especially the publication of some high-value publications, which requires very high articles. This revision is likely to be repeated. The author needs to make many revisions and submit many times before the article can be finally accepted and recognized, so there is no need to panic in this case.

Another reason for the repeated revision of the paper is that there are problems in the author's revision. Many authors have no meaning of revision, or have a poor understanding of revision. Changing it around always fails to meet the requirements of editing, so it is very important to modify it.
