As far as I know, I think the structural art of poetry is like building a house. Structure is the overall structure of the house and the most basic condition for the quality of the house. So whether a poem is good or not depends first on the building materials and methods you use. Only when the frame is set up can you fill in the decoration-image and beautiful language. However, only structure is not enough. Because it is a poem, it must be artistic in order to be truly called structural art. Therefore, I think that the structural art of poetry is the overall thinking and context of a poem.
I see, hehe, you can refer to my opinion.
