In order to improve work efficiency, the author of the troubled article has been published and sent an in-site text message to the administrator to inform me of the publication information, so that we can sort out the publication data and display it in the article information. 2. Recently, I have discovered that some inexperienced authors have their articles written at extremely low prices or under extremely unfair contracts. When we contacted them, we regretted it. We hope that all authors will contact us if someone contacts you about publishing. Maybe we can help you check and compare and evaluate the publishing conditions, and maybe we can help you find a better publisher. In short, don't sign it to others rashly, maybe your writing value is better.
