This paper takes six Chinese Textbooks in the late Korean Dynasty compiled by Wang Weihui and others as the research object, selects and counts the high-frequency words, and analyzes their characteristics from the aspects of syllable number, part of speech, use in modern Chinese, meaning content, dialect background and so on. It is found that only monosyllabic words and disyllabic words appear in the high-frequency words in the late Korean Chinese textbooks, and the parts of speech are mainly verbs and nouns. Modern Chinese uses some words of high-frequency words, and some high-frequency words are no longer used. In terms of meaning and content, high-frequency words are highly related to commercial and trade activities. At the same time, there are some spoken words and a large number of northeast dialect words.

Lee Dynasty (1392-1919) was the last feudal dynasty on the Korean Peninsula. Chinese teaching in this period reached an unprecedented peak, and a number of localized Chinese textbooks emerged. This paper first analyzes the motivation of the compilation of these textbooks from the political, ideological and historical aspects, and finds that the compilation of these textbooks is related to such factors as North Korea’s “Shida” foreign policy, the thought of “Muhua” and the use of Chinese characters to mark Korean in history. Secondly, according to the nature, the textbooks used and published by Lee Dynasty are divided into two types: dictionaries and textbooks, and the existing textbooks are counted according to the previous research. Finally, through the analysis of the specific content of the teaching materials, it is found that these teaching materials have the characteristics of paying attention to oral teaching, strong practicability and cultural teaching function.
