From this perspective, the book Anger needs to conform to the writing characteristics of Songti. Songti is a square and clear Chinese printing font. Its strokes are basically composed of five basic components: horizontal, vertical, skimming, skimming and folding. Horizontal, vertical, straight and neat, suitable for typesetting and writing long articles. These characteristics also need to be shown in Shu Fen's calligraphy, so that the calligraphy works are more standardized and refined. However, in terms of brush strokes, it is still necessary to continue the simple and clean style of Songti to present the unique momentum and style of book indignation.
