① The lyrics of Xintianyou are characterized by two-sentence structure. Because its words are homonyms and are strictly restricted by phrases, it forms a stable form of two sentences and one paragraph. It takes metaphor as a means of thinking in images, chooses life and refines an artistic image with harmonious content and form. This is "seeking things and expressing feelings" or "touching the scene and feeling". In the long-term development of Xintianyou, these two traditional expressions have become their own fine traditions. Usually based on the previous sentence, comparison and the next sentence. The use of Bi Xing is naturally ingenious, appropriate and accurate. The sentence patterns are diverse, the rhythm is distinct, and the rhyming method is flexible and free.

The organic combination of multiple lines and paragraphs can make the short chapter become a continuous Long song, showing richer and more complete content.

As Xintianyou sang, "An empty kiln can't sing". Of course, there are lingering, euphemistic, delicate and frank tunes in Xintianyou, just like the tunes that women miss their lovers.
