Choosing a publishing agency depends first on whether its platform is a third-party guarantee. The more secure it is, the more trustworthy it is. In addition, see if the magazines he recommended are formal or not. Let me tell you that the General Administration of Press and Publication has set up a periodical retrieval window for the convenience of relevant local departments to quickly and effectively identify the legality of publications. In all regular periodicals, the General Administration of Press and Publication will record the periodical information. Newly born publications will enter the retrieval system at the first time, and closed publications will exit the retrieval system at the first time.
