本文介绍清末苗族秀才创造的3种方块苗文,“板塘苗文”、“老寨苗文”和“古丈苗文”。方块苗文是汉字文化圈内的借源文字,在结构和造字法上基本一致,造字法主要有形声和会意,双音符的不多,象形成份极少,大量地借用汉字标音。方块苗文用来记录和创作苗歌,留下了十几万字的苗歌文稿,为我们提供了研究民族历史、民族风俗和民族文学的宝贵文字资料。 This article introduces three kinds of square Miao Wen created by the Miao scholar in the late Qing Dynasty, “Miao” and “Old Man Miao” and “Old Man Miao”. Miao block square is the borrowed source text in the cultural circle of Chinese characters, basically the same in the structure and the method of making characters, the main shape of the calligraphic sound and understanding, few double notes, very few pictographic components, extensive use of Chinese phonetics. Miao block square used to record and create Miao Song, leaving more than a dozen words Miao Song manuscripts for us to provide a study of the history of the nation, ethnic customs and literature of precious literature.
