1. Papers are published in the "publication" contained in the VIP storage: actually, it is a platform provided by VIP for personal use to upload papers. The platform will not verify the qualification of the uploader. Usually, some pirated journals will upload papers to VIP through VIP storage, creating the illusion of regular journals for everyone! Some journals will use fake vouchers to enter the database. For example, the cottage version of Future Scientist first promoted VIP, but later found that only one article could be uploaded to VIP storage. The papers published in br & gt2.VIP do not meet the requirements of evaluation: since it is a professional title evaluation, there are restrictions! Although it is a national periodical in a sense, each unit has its own regulations. For example, some units explicitly require that it be a core periodical or a periodical of a specified category, so even if it is included in VIP. It cannot be used as a comment title.
