To prevent the manuscript from returning to the pending status, the following steps need to be followed:

1. Understanding periodical requirements: Before submitting, make sure that you have carefully read the author's guide and submission requirements of the periodical. These files usually include information such as format, citation method and word limit. Make sure your manuscript meets these requirements to avoid being returned due to format problems.

2. Choose the right periodical: Before submitting a manuscript, make sure that the periodical you choose matches your research field and thesis theme. Choosing a journal that has nothing to do with your research content may lead to the rejection of the manuscript.

3. Maintain the quality of your thesis: ensure the high quality of your thesis, including clear structure, rigorous research methods, full argumentation and reasonable conclusions. High-quality papers are more easily accepted, thus avoiding rejection.

4. Check grammar and spelling mistakes carefully: Be sure to check grammar and spelling mistakes carefully before submitting the manuscript. These mistakes may make the reviewers think that your paper is not professional enough, which may lead to the rejection of the manuscript.

5. Follow the submission process: ensure that the submission process of journals is followed, including uploading the correct file format and filling in the complete author information. If the manuscript does not meet the requirements of the submission process, it may be returned.

6. Respond to the reviewer's comments in time: If your manuscript is submitted for review, you must take the reviewer's comments seriously. Respond to the reviewer's comments within the specified time, and revise the paper according to the reviewer's suggestions. An author who actively responds to the comments of the manuscript is more likely to be accepted by the manuscript.

7. Maintain communication: maintain good communication with journal editors during the submission process. If you have any questions or need help, please contact the editor. A positive communication attitude helps to improve the possibility of manuscript acceptance.

In short, in order to avoid the manuscript being returned to the state to be published, it is necessary to ensure that your manuscript meets the requirements of the journal, maintain the quality of the paper, follow the submission process, and actively respond to peer review opinions. Through these efforts, your manuscript will be more likely to be accepted and published.
