What is the basic writing method of Yuanqu?

As far as Sanqu is concerned, the title is written under the Qupai, and the title (if any) can be on another line, or on the same line as Qupai, separated by a word. Words generally don't line up. The number of sets can be segmented according to qupai. Screenshots of the first two pages (horizontally) are shown in Selected Sanqu of Yuan, Ming and Qing Dynasties by People's Literature Publishing House, and the last one is shown in Selected Sanqu of Yuan, Ming and Qing Dynasties by Jiangsu Ancient Books Publishing House.
