The reasons for the delay of journals may be that reviewers are inefficient in reviewing manuscripts and delay reviewing manuscripts: authors are asked to revise papers, add data or fabricate experiments; Withdrawal of manuscript due to unexpected reasons, etc. In short, whatever the reason, we don't want to see the publication delayed. There are many uncertainties in the publishing process. As authors, what we can do is to arrange the publication of papers as soon as possible and leave enough time to deal with some unexpected situations, which will affect the publication and ultimately affect the promotion and development of individuals.
