CNS is not a single retrieval tool, it is the abbreviation of the initials of three publications: Cell, Nature and Science.
Publishing articles on CNS is the goal pursued by many researchers, and it is also an important basis for selecting Nobel Prize, running for academician and showing the research strength of universities and scientific research institutions. There are few authors who can publish CNS in China, and only one academician of Chinese Academy of Sciences has successfully published an article. Therefore, it is even more out of reach for ordinary authors to publish CNS papers, and there is absolutely no need for ordinary authors to pursue such a high-level publication.
