Qiyin lue

The Qiyin lüe is a rime table that dates prior to 1161. This reference work survived to the present largely because the Song Dynasty historian Zheng Qiao included it in his 1161 encyclopedia ''Tongzhi'' .

The ''Qiyinlüe'' has a close affinity with the ''Yunjing''. Both have tables combining rows for a particular final rime, columns for various initials, and up to four tones . A detailed description of this native Chinese phonological system can be found at rime tables.

The Chinese linguist Luo Changpei wrote a definitive study of the ''Qiyinlüe''.
