Memorable documents written in Dongba scripts, such as diaries and travels, record events in chronological order, which strongly reflect the value of Dongba applied documents. At present, few documents of this type can be seen. In January 2005, dongba He Xiudong, who comes from Tacheng Township, Lijiang City, Yunnan Province, accompanied Mr. Li Zaizhong to visit Aming Ling cave, after that He Xiudong wrote a travel note in Dongba scripts, which is a typical record. This article translates and interprets this travel note, and studies the writing phenomenon, phonetic complement, different graphs of the same word, multiple words in one graph, homographs and allographs of this document.

Letters written in Dongba script are an important type of social documents in Dongba script. Two letters written in Dongba script to scholars have been published and translated before, but no letter of thanks written in Dongba script has been disclosed so far. This article interprets a recently written thanks letter in Dongba script, which can supplement the deficiency of such literature. From the contents of the thanks notes, it can be seen that Dongba culture has been revived in some places. In addition, some unusual writing forms of Dongba graphs appeared in this document, which can be used to supplement Dongba reference books when they are revised.

Focused on Xixia dictionaries, this paper collects and arranges allographs of Tangut script. Its type can be divided into allographs with variant configurations and allographs with form-altered, among which there are more of the former and fewer of the latter. Most patterns of the variations are bidirectional and general. Not only does the formation of the allographs have an objective basis but is also influenced by certain subjective factors such as convenient writing, beautiful figure, and taboo.

There are lots of duplicative components in the glyph blocks of Maya hieroglyphs. Some of them are used to double the meaning or sound value of the original components. Some of them are just the aesthetic consideration of scribal which does not affect the significance of the original components. This phenomenon, which was discovered by earlier Maya epigraphers, still needs researches on its causes and substitution patterns. This essay discussed these two issues based on the rearrangement of the glyph blocks containing duplicative components. From the perspective of graphic structure, the doubling phenomenon existed in both syllabic signs and glyphs. There are two reasons for the doubling phenomenon as such. The redundancy and simplification of signs lead to the sign-internal duplication. The unique spelling rule of Mayan language lead to the repetition of the syllabic signs. From the perspective of glyphs, the doubling phenomenon existed in both compound graphs and couplets which are caused by the recombination of glyphs. The substitution patterns of these phenomenon are the use of doubling signs, underspelling, choosing different variants of the same syllabic sign, and sharing components. All of these four substitution patterns can function both in the glyph-internal and between different glyphs.

Naming script has its rationale, and thus the script name with symmetry reflects some differences and connections among its function, evolution, and propagation. Some scripts reflecting the divergence in its function mirror users’ gender differences, different use areas, the discrepancy between the folk script and formal one, and whether it is official or not. Others reflecting its evolution show that the new script has improved on the basis of the old one. Others again reflecting its propagation give an expression to the connection of character sources, object writing, and character morphology.

Comparative graphology is an important branch of graphology research. It includes adopting the comparative method to analyze two or more kinds of scripts in order to find the differences and relationships between these scripts. However, the angle of script comparison is somewhat monotonous and not systematic enough at present. This article starts from making a brief introduction to setting the comparative targets, selecting the comparative materials, choosing the comparative contents, finding the starting point of comparison, choosing the framework or theory for comparison, and finally aiming at finding the certain paradigm for the comparative study of scripts.

Expression type for mixed-use of Dongba characters can be divided into dominant type and parallel type. Causes for mixed-use includes three points: 1. similar or compatible patterns are the precondition for mixed-use; 2. certain relation exists among semantics of words represented by characters, or characters belong to the same classification in terms of meaning or have correlative meanings; 3. outcome is obtained during self-adjustment transitional stage of internal character of writing system. There are three solutions to solve the problem of similar characters: 1. re-distribution of characters’ functions; 2. integration of characters; 3. reconstruction of expression which is embodied in two aspects, including ideographical and phonetic expression transited from ideographical expression to additional phonetic complement, and transition from ideographical expression to pure phonetic expression.
