China Journal of Medical Education is the core periodical, because its sponsor is Chinese Medical Association. China Journal of Medical Education Exploration cannot be regarded as a core periodical, because it is sponsored by Chongqing Medical University, although it is sponsored by Chinese Medical Association. Chongqing Medical University is not a 2 1 1 institution at present. Whether a magazine is a core periodical depends on its organizer and organizer. If so, it depends on the level of the organizer. If there is no organizer, it shall be decided by the level of the organizer. Therefore, the titles of some magazines are "China ×××××" or "China ××××", which are not necessarily national (China brand) magazines. This depends on whether it has a contractor, and if so, the contractor shall prevail. Therefore, if you want to vote for a national magazine, it is best not to have an organizer. The organizer is a national first-class society. If there is a contractor, it is best for the contractor to be a 985 college, or some 2 1 1 colleges, or a * * * institute of Chinese Academy of Sciences. That is, the leader of this organizer is a deputy ministerial official. (Generally, the leaders of most ordinary undergraduate colleges are departmental level, and higher vocational colleges are deputy halls. If some magazines are published by a publishing house and the boss may be a departmental cadre, then this magazine can only be regarded as an ordinary CN number, a general provincial publication. There are no lower-level publications.

So the level of publications is: (provincial publications)-(national core)-(authoritative publications)

(1) Journals above the provincial level refer to professional academic journals published by relevant departments and academic organizations above the provincial level, journals published by ordinary undergraduate colleges (all with ISSN and CN numbers), or foreign professional academic journals above the provincial level (all with ISSN numbers).

(2) Core journals refer to the journals included in the National Science Library of China Academy of Sciences "China Science Citation Database" (CSCD, the latest core edition) and "China Social Science Citation Index" (CSSCI, the latest core edition) of China Social Science Research and Evaluation Center of Nanjing University. If they are not included in the latest core version, proof that they include the current version should be provided.

(3) Authoritative publications:

1 refers to academic journals in related fields sponsored by national ministries and commissions, research institutes affiliated to China Academy of Sciences and China Academy of Social Sciences, and national professional societies (excluding branches, research institutes and associations) in CSCD and CSSCI catalogues.

2. Papers published in core journals or foreign academic journals are cited by SCI, EI, SSCI, A &；; The full text of HCI.
