A short poem is defined as a three-line poem, generally no more than 30 words.
100 songs in the divine comedy are all written in "three-line rhyme" or "three-line chain rhyme".
Each song is a long string of three-line poems connected by a link.
Precautions:
No matter how many words a poem has, no matter how many lines a poem has, as long as it is more than three lines, it is not a miniature poem.
This is the "rule" of micro-poetry, and this "rule" is also the basic feature that micro-poetry stands out from small poems and becomes an independent poetic style.
Any exploration and innovation of micro-poetry, whether in content, form or writing technique, must find a "big stage" to display its talents in the "small world" within these three lines, which is a "restriction" to "freedom".
