本文通过考察苗、汉两种语言古今语音演变的事实,论证两者存在许多共同之处。如在古代都有复辅音(pl、kl…)、鼻冠音(mp、nt…)、清鼻音(m、n…)、小舌音(q、qh…)。这些语音过去认为是苗语独有的,现在在古汉语中找到相同的例证。此外,鼻音韵尾-m、-n、-η,塞音韵尾-p、-t、-k,以及声调由四个分化为八个的发展变化也是苗、汉两种语言相同的。 This article examines the fact that the two languages ​​of Miao and Han evolved from ancient to modern phonology, demonstrating that there are many similarities between the two. As in ancient times have complex consonants (pl, kl ...), nasal crown (mp, nt ...), nasal clear (m, n ...), small tongue sounds (q, qh ...). These phonetic sounds used to be unique to Hmong, and the same is now found in ancient Chinese. In addition, nasal rhymes -m, -n, -n, stoppest -p, -t, -k, and tone changes from four to eight are also the same in both languages.
