The ancients wrote poems without grids. They can start with two squares, or they can put the poem in the middle of the manuscript paper. Punctuation in poetry is actually a writing tool, sometimes used and sometimes not used, depending on the actual situation.
Poetry is a style that can best reflect social life. It is full of rich imagination and feelings, often expressed in a direct lyrical way, and in a delicate and harmonious degree, especially in a distinctive rhythm. In form, poetry is not based on sentences, but on behavior, and its branches are mainly based on rhythm rather than meaning.
