Of course, it is the first review of editors, mainly to examine whether your paper meets the requirements of running a magazine, that is, whether the content belongs to the category of a magazine. It seems that after the preliminary examination, you have to pay money (some don't want it) and then send it to an expert for review. This process needs to be revised repeatedly, and it can be queued for publication after review. The magazine will inform you of the specific publication time. Generally, it takes half a year or a year for a good magazine to be officially published.
