Journal C refers to CSSCI (Chinese Social Science Citation Index). It is used to retrieve the essays and literature citations in the field of social sciences in China.
Class A, Class B and Class C are simple identifications of periodical level by some units, which are not necessarily and inconsistent. CSSCI, a journal of humanities and social sciences, is searched by Nanjing University, and its level is higher than that of Peking University, because there are more magazines in Peking University.
Specifically: Journal C = CSSCI = NTU core journal, and the core journal of Peking University is generally called CORE. The core range of NTU is smaller than that of Peking University, so the C value is higher. The top periodical of CSSCI is recognized as A by some schools, which is the highest among Chinese periodicals. And publication B is stipulated by each school according to its own standards. Therefore, if you want to publish a paper, before choosing a periodical, you should go to the relevant department of our school and ask about the periodical classification catalogue of our school, and then you can decide who will contribute.
Generally speaking, a is superior to c and b in terms of academic level.
