1. Stop for a few days and give yourself a few days to digest this matter. Calm down for a few days, and then go back and read the rejection letter more carefully.
2. Consider appealing the editor's decision. If you are not going to appeal the editor's decision, it's time to start preparing to contribute to another journal.
Consider asking someone to edit this article. If the editor or reviewer mentions language problems, consider asking colleagues who are proficient in English to proofread the article, or consider asking professional editing services to improve the language of the article.
4. Choose another magazine and contribute. After reviewing the reviewer's comments, improving the article and editing it, you can choose the next journal to contribute.
Don't be discouraged, remember that rejection is completely normal. Even if the article is submitted to another journal, it may be rejected.
