Journals have more words than periodicals, usually starting with about 4000 words on two pages. From this point of view, we can see that journals attach importance to the quality of articles, because a page can only be up to 2500-3000 words, which is far from being a good article.

Journal, the original meaning, is an academic journal run by a university, which specializes in reporting academic research results. At first, the nature of university journals was comprehensive, not limited to arts and sciences. After that, specific subject editions appeared, such as "Humanities and Social Sciences Edition" and "Natural Science Edition", which led to the division of arts and sciences.
