Contact linguistics takes the series of linguistic phenomena in the process of language contact as the research content, and explores the changes of the languages and their results. When language contact occurs between Chinese and Korean, the linguistic phenomena occurring in the aspects of phonology, syntax, vocabulary, and characters are one of the important results. Sino-Korean Rhyme Dictionaries are language tools that are mainly arranged by rhyme. Such dictionaries annotate the pronunciation of Chinese characters, correcting the incorrect pronunciation of Chinese characters in Korea, and occasionally interpreting the meaning, and recording some glyphs of variants, which provide the convenience for extracting poems and lyrics, as well as reciting rhyming characters. From the perspective of the developmental history of Chinese dictionaries in Korea, rhyming books are the beginning of Chinese dictionaries in Korea, which have abundant content and significant value, and are indispensable and valuable materials for the study of Chinese-Korean contact linguistics.

汉语语音的序列由声、韵、调三个方面的序列来构成。把声、韵、 调按一定的顺序依次排列起来，就形成了语音的序列。由于汉语语音的 序列由三方面构成，因而决定了汉语古典音序法序列原则的多重性；或 以韵部的顺序为第一序列，再按声、调的序列编排；或以声母的顺序为 第一序列，再按韵、调的次序来编排。因此，古典音序编排法具有多样 性的特点。 朝鲜1443年创造了《训民正音》，由此可以用音位字母来注汉字 音，开始编纂以《训民正音》注音的韵书。因为《训民正音》是音位文 字，初声（声母），中声（韵头、韵腹、元音的韵尾）、终声(-m, -n, -ŋ, -p, -t, -k)都具有音位单位的序列性，因此朝鲜韵书依这些音位 的次序来做汉字的序列，结果大幅度增加其多样性。
