The third edition of a periodical is the minimum requirement for the three editions to be published together. Papers are published by layout, and the third edition is because journals have requirements for the number of words in papers. If the layout is small, it may be difficult to be included, so it is difficult for many authors to start publishing two editions. Generally speaking, it is common for people to publish a one-and-a-half-page or two-page paper, but many magazines don't accept articles with several pages. The essay may not have any reference value, so the author should pay more attention to the writing of the paper and make preparations in advance according to the submitted journals.
