Well, I actually know this question, but it's generally not convenient to talk about it, because after all, this is not a general publication, but SCI, because it's really difficult for domestic cores to publish now, and publishing SCI is indeed an option. SCI is divided into several districts, the districts 2 and 3 are more expensive, and the districts 4 are cheaper and the audit is stricter. A friend of mine is looking for Tao Tao Paper Network to arrange publication. The cost is not cheap, but the publication is smooth. My suggestion is, if you can't contribute and publish by yourself, then go to them again. . If you are not sure, please feel free to ask.
