Rime table
The oldest known rhyme tables are a version of the "Yunjing" published with prefaces dated 1161 and 1203, and the "Qiyin lüe", which was included in the 1161 encyclopedia "Tongzhi". The two are very similar, and are believed to be derived from a single version pre-dating the Song dynasty. The tables were accompanied by a body of teachings known as "mēnfǎ" (), including rules for placing fanqie spellings that did not conform to the system within the tables.
