The Nature of "Zhi Ru" Rhyme in the Book of Revised Edition of Zhong Zhou Complete Rhymes

The Nanqu Rhyme book, Revised Edition of Zhong Zhou Complete Rhymes, is created by Zhou Ang in the Qing Dynasty. The "Zhi Ru" Rhyme is considered to be an extreme southern form of the system of Zhong Yuan Yinyun. Senior scholars had discussed the nature of it superficially. This paper, based on the relevant rhyme books, rhyme tables and text data, re-examines the the nature of the "ZhiRu" Rhyme, and differentiate problem from the initials of "Zhi、Zhang and Zhuang". It is believed that the vowel of "Zhi、Zhi、Zhi"and "Yu、Yu" in ZhiRu Rhyme are to be supplemented by shift process"∫、y", of which the initials of "Zhi、Zhang" and "Zhuang"are still different.
