The Yunjing is one of the two oldest existing examples of a Chinese rime table – a series of charts which arrange Chinese characters in large tables according to their tone and syllable structures to indicate their proper pronunciations. Current versions of the Yunjing date to AD 1161 and 1203 editions published by Zhang Linzhi (). The original author(s) and date of composition of the Yunjing are unknown. Some of its elements, such as certain choices in its ordering, reflect features particular to the Tang dynasty, but no conclusive proof of an actual date of composition has yet been found.

The Yunjing is one of the two oldest existing examples of a Chinese rime table – a series of charts which arrange Chinese characters in large tables according to their tone and syllable structures to indicate their proper pronunciations. Current versions of the Yunjing date to AD 1161 and 1203 editions published by Zhang Linzhi (). The original author(s) and date of composition of the Yunjing are unknown. Some of its elements, such as certain choices in its ordering, reflect features particular to the Tang dynasty, but no conclusive proof of an actual date of composition has yet been found.
The Yunjing contains 43 tables (), each of which tabulates combinations of a particular final rhyme (listed in rows) with various initials (listed in columns), in up to four tones, to show in a grid pattern all possible syllables. Empty circles on the grid denote that the authors were unaware of any word with that particular pronunciation. By locating a character in Yunjing, a reader could identify its initial consonant (by looking at its column) and its "rhyme", or main vowel and ending consonant (by looking at its row), and combine the two to obtain the word's pronunciation. Zhang Linzhi's prefaces list a total of 36 possible initial consonants () – by comparison, modern Standard Chinese only has 23 and modern Cantonese only has 18 or 19.
