The internal publication here refers to a magazine that has no unified CN number in China, but only the internal publication number in the province. If a paper has been published in a magazine with CN number, and it is published in such a journal, is it considered as more than one submission? Because most domestic journals do not explicitly require papers not to be published in their solicitation enlightenment, this issue is also controversial. At present, there are three views on this issue: the first one is not to contribute more than one manuscript. Most people hold this view, even including many magazine organizers in China. For example, in the scientific research achievements published on its website, Chengdu Vocational and Technical College counted the publication of such a paper in two journals. In the economic forum of the National People's Congress, most netizens think that it is not a multi-contribution. Second, there is more than one draft. It is considered that since there is an internal periodical number, it is a member of a regular and legal periodical. Repeated publication of papers is of course a great contribution. Third, it is allowed to publish it in internal magazines before submitting it to other magazines, but it cannot be the other way around. In my opinion, such repeated publication is indeed suspected of multiple contributions. You'd better call the magazine in advance to find out the problem.
