1, font width and flatness: the font of official script is usually wider and flatter than that of Xiao Zhuan, because when writing official script, the horizontal painting is more stretched and the vertical painting is relatively short. This glyph gives people a sense of stability and solemnity.
2. The horizontal painting is long and the vertical painting is short: the horizontal painting of official script is usually longer than the vertical painting, which is an important feature of official script. This feature makes the glyph of Lishu wider and flatter, and at the same time increases the sense of movement and rhythm of the glyph.
3. Free expansion: Free expansion of official script is reflected in the continuity of its strokes. Li Shu's strokes start, end and turn, which makes Li Shu more flexible when writing, and also increases the layering and three-dimensional sense of the font.
