Take sci journals as an example. Early-warning periodicals refer to periodicals that publish a large number of articles in a certain period of time, have unusually high page fees, or are suspected of being manipulated by influencing factors. As long as you have one of these points, it is possible to enter the catalogue of early warning journals. These periodicals have publishing risks, but they are not absolutely unpublishable. If it is really your favorite periodical, you can wait and see for a while. Some periodicals will be eliminated from the catalogue after the indicators are normal, so you can pay attention to the catalogue of early warning periodicals in time.

However, if the author publishes a paper to promote his professional title, it is best not to choose early warning journals to avoid the phenomenon that the published articles are not recognized. Not only the promotion of professional titles, but also graduation, scientific research, and Expo application for publishing articles, we should pay attention to avoid choosing early warning journals. Which directory of early warning journals should the author refer to? Units and schools have a catalogue of early warning periodicals, with the publications published by units and schools as the main reference; If not, you can refer to the catalogue of early warning journals of Chinese Academy of Sciences.

In the early warning catalogue of the Chinese Academy of Sciences, the risk level is divided into three levels: high school and low school. What the author needs to pay attention to is that if a publication was a low-risk early warning journal last year, it will be deleted from the catalogue this year, which means that the non-compliance of the publication has been corrected and it is no longer an early warning journal, so such a publication can be published with confidence.
