This is a kind of micro-poem, also called micro-poem. Miniature poetry is an independent style with strict restrictions. Therefore, we define mini-poetry as a poem within three lines, generally no more than 30 words. Three-line poems have existed since ancient times. Three-line poetry, this genre of poetry, has been written by poets in history; Among them, Dante's masterpiece Divine Comedy is a poem that uses up to three lines of rhythm. 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. Xu Shan's poetry collection "In order not to be confused-Xu Shan's short poems1000" (2004) is written in three lines. At present, Li, the author of this poem, has continued to write a three-body poem named Li's Three-body Poem with reference to the form of the Pear Flower School, and published it on the Internet in the form of a blog. There is also a poetic style: the three-story book can be said to be a three-line poem.
