When submitting a paper, it is generally required to attach a "cover letter". A good "cover letter" can not only make the article icing on the cake, but also directly determine whether the paper is hired. My personal experience, taking published papers as an example, is summarized as follows:

Dear editor:

We would like to submit the attached manuscript entitled "Title of the Paper", and we hope to consider publishing it in the name of the journal.

The work described has not been submitted to other places for publication, all or part of it, and all listed authors have approved the attached manuscript. We believe that two aspects of this manuscript will interest ordinary readers of your magazine.

I. Highlights of the paper 1.

Second, the highlights of the paper 2.

Thank you very much for your time and consideration.

You are sincere,

Author's name

Note: the highlights of the paper must be concise and clear, and must be innovative, highlighting the difference between your article and other published papers. This is the main content of the cover letter.
