Yunjing

The Yunjing is the oldest existing rime table. Current versions of the ''Yunjing'' date back to the 1161 and 1203 editions published by Zhang Linzhi .

In theory, the ''Yunjing'' is a two-dimensional representation of the Middle Chinese phonological system. The preface lists 36 initial consonants ; see the link below. The Yunjing contains 43 charts , each of which tabulates combinations of a particular final rime with various initials , in up to four tones. A detailed description of this native Chinese phonological system can be found at the rime table article. For further information about the ''Yunjing'', see Coblin and Pulleyblank .
