Whether the submission can be made depends mainly on the requirements of the soliciting party. Those that meet the requirements can be submitted.
Generally speaking, in practice, three poems with four lines and seven words have actually reached most standards. For example, the genre of "Xu Zhimo's Micro-poetry Competition" is modern micro-poetry (that is, within 140 words), with no more than four lines, and no more than five metrical poems are submitted. In the face of such competition, you can make a contribution.
Precautions for submission:
Entries must be original works that have not been published in public publications and newspapers at home and abroad. If plagiarism is found, the entry qualification will be cancelled.
Submission also needs to study the style of submission platform, previous articles, etc. Only by understanding the tonality of the platform can we prescribe the right medicine, write articles that fit the platform, and successfully contribute.
