The preface, postscript, foreword, and general notices of the Korean Chinese dictionary, contain not only the reason and purpose of compiling the dictionary and the relationship with other Chinese dictionaries, but also the understanding and even the view of Chinese characters in ancient Korea. Combining the contents of the preface, postscript, foreword, and general notices of Korean dictionaries, as well as other Korean Chinese literature, it analyzes Korea’s understanding of Chinese characters, and explains the main contents of Korea’s view of Chinese characters from different dimensions, such as the dissemination of Chinese characters, Chinese characters ontology, and the use of Chinese characters.

As the most commonly used Chinese character dictionary in Korea, Korea's the Chinese-Korean Dictionary was originally revised from the Large Chinese-Korean Dictionary(1964) and retained Chinese characters from ancient times to around 1950. Since the initial edition of 1973, the dictionary has been reprinted several times and has not been revised. In view of the deletion of some worthwhile Chinese characters in the Chinese-Korean Dictionary on the basis of the Large Chinese-Korean Dictionary, or the inappropriate deletion of some entries, and the many imperfections in the compilation style, such as the lack of illustrations, Chinese phonetic notes and Chinese annotations, etc., this paper holds that the Chinese-Korean Dictionary should be revised and properly included and deleted. In addition to the valuable Chinese characters, and improve the compilation style, so that it is more detailed, more convenient for readers to use. At the same time, in order to overcome the limitations of paper dictionary, expand its capacity, update entries in time, and make it easy for readers to carry, it is necessary to launch the Internet dictionary of the Chinese-Korean Dictionary.
