There are five main types of Vietnamese orthographic texts among the extant Chinese literature. This paper introduces these five types of orthographic literature and summarizes their main contents as orthographic forms, orthographic sounds, and orthographic meanings to regulate the use of Chinese characters, thus deriving the orthographic criteria reflected in these five types of Vietnamese orthographic literature. In addition, we explore the background of the formation of Vietnamese orthography in relation to the ecology and actual use of Chinese characters in Vietnam at that time, thus revealing the value of Vietnamese orthography to theoretical studies of orthography, to the study on the spreading value of Chinese characters, and to the compilation of dictionaries.
