In the process of publication, it is very common for papers to be rejected and revised. It is rare to pass three audits at a time. Generally, it needs to modify 1~2 times to pass the approval. One author asked: Is there a limit to the number of revisions? As far as Bian Xiao knows, there is no clear definition of this. Generally, papers with good quality can be revised 1-2 times; On the other hand, if the quality is not good, it may need to be revised 3-4 times.
