Whether an academic paper can be submitted to multiple journals at the same time is not a simple answer. In some cases, this is acceptable, but in other cases, it may be regarded as immoral behavior.

First, we need to know what multiple contributions are. Multi-contribution means that the author contributes the same article or different articles written by its core content to two or more scientific journals at the same time. This kind of behavior is forbidden in academic circles because it may lead to repeated publication, waste resources and damage the author's reputation.

However, in some cases, it is acceptable to submit more than one manuscript. For example, if an article is rejected by one journal, the author can submit it to another journal. In this case, the author should ensure that the consent of the first journal is obtained before submission, and explain the situation in the submission letter. In addition, if an article is accepted by many journals, the author can choose to publish it in any one of them.

In short, it is not absolutely forbidden to submit more than one manuscript, but it is unacceptable in some cases. If you plan to contribute, I suggest you read the submission guide of relevant journals carefully and abide by relevant regulations. In addition, you can also consult your tutor or other professionals to get more suggestions on how to contribute correctly.
