This article delves into the development of Japanese Chinese character variations, and how they fit into the broader study of Chinese characters. By examining the differences between early Japanese kanji and modern Japanese writing systems, as well as the varying approaches of Chinese and Japanese scholars in studying Japanese kanji, we can propose a more fitting classification and naming method better suited to studying Chinese characters. To that end, we take the Wamyō Ruiju Shō (倭名類聚抄) as an example, exhaustively sorting out the situation of variant characters in the manuscript across different eras, and referring to other ancient Chinese dictionaries from the same period. This article introduces concepts like “inherited variants” and “Japan saved variants” to make studying these characters more comprehensive.

고문읽기와 쓰기는 우수한 중국 전통 문화의 계승과 발전을 위한 기초 능력이다. 현재 고문 교육은 학습 효율이 낮고, 문턱이 높으며, 목적성이 부족하다는 세 가지 문제점이 존재한다. 고문읽기와 고문자에 대한 두려움은 많은 청소년들이 맞닥뜨리고 있는 실제 문제이다. 본 연구는 고대 중국어 교육의 특징과 실제에 근거하여 대규모 고적 코퍼스의 통계 작업을 통해 1,000개의 한자를 선정하였다. 한자의 자형, 자음, 자의, 용자 네 가지 측면에서 각 등급별 기준을 설정하고, 한자 학습의 우선순위를 반영하여 ｢고적한자등급자표古籍汉字分级字表｣를 개발하였다. 이 표 에는 1급 105자, 2급 340자, 3급 555자를 수록되어 있다. 청소년에게 고문 학습을 위해 한자학습 자료를 제공하는 것은 고적 한자의 점진적 학습을 도울 뿐 아니라 청소년이 가지고 있는 고문 학습에 대한 부담감을 줄여주고 고문 읽기 능력을 향상시켜 줄 것이다. 더 나아가 중국의 우수한 전통 문화를 계승하고 발전시키는 데 도움을 줄 것으로 기대한다.

In actual language corpus, there exists a phenomenon of semantic dislocation between “Du1 (度1)” and “Du2 (度2)”. The sense of “Du1 (度1)” is mainly a noun, but it also has a verb sense of “according to rules”. On the other hand, “Du2 (度2)” is mainly a verb, but it has a noun sense, which is a military term. Based on domain restriction analysis, this paper analyzes the syntactic position, semantic evolution and domain restriction changes of the dislocated semantics, and examines the semantic evolution process of the two. It is found that when the verbal noun “Du (度)” undergoes a part-of-speech change, it is often influenced by external factors of language, leading to a sudden mutation in domain restriction. However, when “Du (度)” is only subject to internal language mechanisms, its part-of-speech does not change, and it only extends new meanings within the domain field and transitional domain field. Therefore, the study of domain restriction has practical significance in the classification of Chinese verbs and nouns.

There are a lot of problems in the existing databases of ancient characters, such as the digital processing obstacles of Gaiji (characters excluded in character sets), the defects of information technology, and a lack of completeness. The newly released “digital resource library for intelligent Internet search of ancient characters” makes the following breakthrough: it achieves full coverage of all types of ancient characters in all dynasties, and realizes the carrier conversion of character data with strict digital standards, allows the the further processing of materials and the intelligent recognition search technology, and forms the series of thematic databases. There are two major tasks for the future development of the digital resource library of Chinese characters: the development of international standards for ancient character sets, and the further processing and sorting of ancient character materials for the intelligent research of ancient characters.

Big data and AI are the two major technical means of development in the current era. Thus, whether Chinese grammatology can use new technologies to achieve new developments following the trend as such is precisely the new problem and new field of the development of philology. The scientific research work on computer recognition of ancient Chinese characters has been carried out for more than 20 years, and it has achieved good results in methodology. However, it is only in the past three years or so that the real application has been made. In this regard, this paper summarizes the research status of ancient Chinese character computer recognition, attempts to analyze several factors that restrict the ancient Chinese character computer recognition from experiment to application, and puts forward the future development of this work.

The development of Nom characters is promoted on the basis of and in attachment with Chinese characters, and in this regard the Phonetic Annotation of the Thousand Character Classic 《千字文解音》 compiled in the late Nguyen Dynasty in Vietnam was a very practical textbook for learning Chinese characters and Nom characters. Based on categorizing Nom characters, the paper intends to clarify several notions on Nom characters of the Phonetic Annotation of the Thousand Character Classic. In the beginning, Nom characters can be divided into two major types: the directly borrowed Chinese characters and the independently invented ones. The former includes borrowing sounds, meanings, and both. The latter, according to the components of Chinese character formations, can be divided into the pictophonetic of Chinese characters and that of Nom characters. In the last part of the article, we summarize the relationship between Chinese characters and Nom characters. It is necessary not merely to consider the relationship but to understand the comparisons between them. With the aid of studying Nom characters, we can find that irrespective of whether they are directly-borrowed from Chinese or independently invented, the sound of Chinese characters is the most important feature for them. But we cannot ignore the ideographic parts of Nom characters because they, on the one hand, make up the phonetic deficiency of Chinese characters while promoting the development of Nom characters on the other. In our modern society, Chinese characters and Nom characters came to drift apart, and the latter especially was withdrawn from the historical stage, but the traditional culture of Vietnam is still recorded in literature both in Chinese characters and Nom characters. Moreover, the Nom character is one of the most important representatives of Vietnam’s traditional culture. For this reason solely, this research shall be a great help to further understanding of significant cross-cultural aspects between China and Vietnam, and more specifically of histories related to the spreading, application, and development of Chinese characters in Vietnam.

Clean the number of variant in the dictionary be handed down from ancient times, in order to describe the characters of standardization and the transmission condition of Chinese character. Through sorting out the unauthorized character in Song Edition Yupian宋本玉篇, we can find that the development of Chinese characters is a dialectical process: ancient SuTi, today Zheng Ti; today Su Ti, ancient Zheng Ti. The evolution of Chinese characters is from standard to the variation and from the new standard to the variation. Each standard of characters all make characters tend to brief and easy-to-use. The new standard substratum is always the original constraint mechanism. The original constraint mechanism is always adapt to the new development and presents different canonical form.

Our ancestors made the brilliant achievements in studyingCharacter structure in Ancient China, which laying the foundation for today’s research. From Han to Qing dynasty, the achievements of Characterstructure study mainly are: First, realized the importance of Characterstructure; Second, improved the systematical theory about Characterstructure: 1. The theory of grapheme constituting character. 2. Thehierarchical structure theory about Character. 3. The theory of thegrapheme having different functions. Third, made a substantial researchabout Character structure: 1. The research about the character. 2. Theresearch about the grapheme. 3. The systematical research about the whole Chinese Characters. But these researches had some shortcomings: not making concepts distinction between “ radicals ” and “ Chinese character component”; lacking of the character’s formal structure research, and so on. In ancient China, we had already constructed the systematical theory about character structure, this fact is helpful to correct the mistake about the claim that “in ancient china, there was no scientific theoretical system of philology”.
