Provincial papers are papers published in provincial journals, which are at the provincial level. If you have requirements for the core, it is a general journal, a non-core journal, or it can be called CN level. If there are any major categories, there are one, two, three and four categories. One category is generally the core journals of NTU. Provincial periodicals, although not core periodicals, are now in short supply. They will be published in half a year. If you are in a hurry, you can try to get help from a professional organization like Tao Tao Paper Network. It can be published in 2-3 months, which can save a lot of things.
