There are some commonalities and characteristics,which are reflected in forms of the nasal rhyme between the Proto-Miao language and the modern Miao dialects.The evolution of the nasal rhyme in the Proto-Miao language is mainly restricted by the initials,and also restricted by the tones in some cases.The difference between Yin and Yang tones,the different local pronunciations and methods of initial will all cause the evolution and differentiation of rhyme.Its nasal rhyme tends to fall off nasal coda in Yarong Miao dialect,which leads to the merger of some rhymes and seems to have been simplified,but the rhyme will be divided because of the restriction of initial and tone,so the correspondence of the rhyme in Miao language is more complex.
