《長興四年中興殿應圣節講經文》性質、作者與用韻研究=On the Nature, Author, and Rhyming of Text Preached on the Emperor’s Birthday in the Zhongxing Hall in the Fourth Year of the Changxing Era= 程興麗； 許松
The Text Preached on the Emperor’s Birthday in the Zhongxing Hall in the Fourth Year of the Changxing Era kept among Dunhuang documents is not a draft for a sermon but rather an example of serious rhythmic prose. The rhyme patterns match those of metrical modern-style librettos with additional tonal patterns in parallel verse. Its author is likely Li Congrong, the Prince of Qin, and scholars in his service, who together polished a draft written by Yun Bian for preaching the Karunikaraja Sutra.
