Interpretation of the shapes and meanings of letters that have the meaning of '足' in Choseo shapes(草書)

The type of Choseo shapes(草書) included in the Chinese Internet site and Choseo font(草書) autobiography was referenced. Looking at the changes in the shape structure, he paid attention to the regularity of the Choseo shapes(草書). The specific changes in the shape were explained voluntarily. The main research subjects of this paper were 夂, 止, 癶, 走, 辵, 足, 舛, 廴, 素, and 彳, which are representative Chinese character 疋 with '足' meaning, and the Choseo shapes(草書) and characters of related Chinese characters. Although these letters appear to be irregularly changed strokes, the rules of these strokes also occurred according to the accumulation of time. The meaning of the letters for these Choseo shapes was explained. These Choseo shapes were not only understood as works of art, but they were also able to find their meaning as letters. This is the deep significance of this paper. However, the Choseo type has as many diverse letters as other typefaces, and its simplicity has been greatly deepened. However, Choseo shapes have various shapes of letters. And this has become very simplistic. In Choseo, more of the same characters are found than other font. In this paper, it was not possible to discuss them due to the limitations of the width and the lack of data accumulation. This will be left as a future research project. We hope that more Choseo research results will be accumulated in the future.
