Chu Bamboo Book in Anhui University (vol.2) published in August 2022 (hereinafter referred to as “Anda II” or “An Da Jian”) is the latest collation of the bamboo slips of the Warring States Period in Anhui University by the Research Center for the Development and Application of Chinese Characters of Anhui University, which includes two parts: Zhongni Yue and Cao Mo Chen. Through a preliminary comparison and analysis of the writing phenomena corresponding to the purposes of such articles as Cao Mo Zhi Chen and Zhong Ni Yue in An Da Jian, Cao Mo Zhi Zhen in Shang Bo Jian (Chu Bamboo Book in Shanghai Museum), the author found some special phenomena related to He Wen. For example, although the writing of Cao Mo by An Da Jian seems to have various ways of writing, this way of writing may contain a profound interpretation of the meaning of the text by the scribes at that time. This writing phenomenon is of great value for in-depth consideration: 1.When the two words “Shang Xia (上下)” and “Zhi Suo (之所)” can be taken apart or not, the words that cannot be taken apart are often written as He Wen, and the words that can be taken apart are often not written as He Wen; 2.When the original two words “Jun Zi (君子)” and “Xiao Ren (小人)” cannot be separated, the written form of He Wen may represent a special emphasis. At the same time, through a comparative study of the use of Chinese characters in Cao Mo and Zhongni Yue, we may speculate that although Cao Mo and Zhongni Yue may not belong to the same style of writing, at least in the arrangement of He Wen, There may be some similar writing logic in these two chapters - the speculation about this writing logic may be used in the analysis of other difficult texts in Zhongni Yue.

合文是自源的表意文字發展不成熟階段的一種特殊的文字現象，東巴文也不例外。東巴經中的合文現象尤其普遍，並且東巴經較爲完整地保留了合文形成發展的歷時軌跡。究其形成原因，可以從內因和外因兩方面去探討。其內因表現在：文字發展不成熟，文字單位與語言單位存在參差關係；概念的整體性導致文字符號書寫時緊密連接；遵從書寫時的“事理性”導致合文。其外因主要表現在：書寫空間的局限造成字符的臨時合書；不同符號之間長期並聯使用易導致合書；因具有相同部件而合書；迎合東巴經整體書寫形象性、趣味性的特點。
