Hlou-Shum languages: Difference between revisions

"The incidence of these tones [A, B, C] in Chinese, Tai and Hmong–Mien words follows a similar ratio 2:1:1. Thus rhyme dictionaries such as the Qieyun divide the level tone between two volumes while covering each of the other tones in a single volume. Vietnamese has a different distribution, with tone B four times more common than tone C."
