Periodicals with real publishing qualifications usually have clear publishing units, and relevant publishing license information can be found on the website of the State Administration of Press, Publication, Radio, Film and Television. Fake journals often don't have this information, or the information provided is false. Journals with real content quality usually publish high-quality academic papers, which have gone through a strict peer review process. Fake journals may publish low-quality papers or there is no peer review process at all. Genuine periodicals are usually distributed through regular bookstores, libraries or other sales channels, while counterfeit periodicals may be sold through informal channels, such as personal websites and social media platforms.
