Chinese calligraphy is like a rare, exotic flower in the history of civilization, and is a unique gem of Oriental culture. Graphically, it is comparable to painting in its ability to evoke emotion through a rich variety of form and design. As abstract art, it displays the rhythmic and harmonious flow of music. And from a practical point of view, it is written language.
Writing is a tangible representation of spoken language.
In the Seal Script style, both vertical and horizontal lines are fine, uniform, and foreceful, and tend to be slightly pointed at the ends. The Lesser Seal Style is characterized by winding, wiry, carefully drawn lines, in contrast to the less refined Greater Seal Script. The Official Script Style emerged in response to the need for a writing style that could be quickly executed, to deal with the burgeoning volume of official written documents. Its major features are stick-straight vertical and horizontal lines and a tight structure. The Official Script style was much more convenient to write than the Seal Style, and saved uncounted hours of precious time.
