Although Tang Dynasty regulated verse mainly relies on real words, the role of auxiliary words cannot be ignored. Auxiliary words mainly include particles, conjunctions, prepositions, adverbs, and interjections, which can effectively mediate the sentence structure and enhance the artistic expression of the poem. As the key point of the sentence, they have a highlighting function and can revitalize a single line of poetry or even the entire poem. They are the objects that poets focus on refining. They can connect the sentence flow and act as a sentence structure hub, forming sequential, transitional, and progressive relationships between the upper and lower sentences, thereby enhancing the logical rigor of the poem. Auxiliary words can also adjust the rhythm, making the poem full of ups and downs and avoiding plain narration, presenting the charm of twists and turns. Most importantly, auxiliary words can ingeniously create emotional disparities and exert the function of conveying emotions, thereby evoking readers' resonance. Of course, although auxiliary words have many functions, if used excessively, they may make the sentence meaning too clear, lacking tension and jumpiness, resulting in weak and powerless poetry. It is necessary for poets to properly grasp the boundaries of the use of auxiliary words.
