Official script is also called "official character" and "ancient book". It is a font produced on the basis of seal script to meet the needs of convenient writing. The seal script is simplified, and the uniform circle lines of the seal script are changed into straight strokes, which is convenient for writing. This is a font created in prison, which can be divided into "Qin Li" (also known as "Guli") and "Han Li" (also known as "Lishu"). The appearance of Lishu is a great change in ancient writing and calligraphy.
Official script is relative to seal script, and its name originated from the Eastern Han Dynasty. The appearance of official script is another great change of China characters, which brings China's calligraphy art into a new realm, is a turning point in the development history of Chinese characters, and lays the foundation for regular script. Official script is flat, neat and exquisite. In the Eastern Han Dynasty, the painting methods such as skimming, pressing and pointing were beautified as upward provocation, with different degrees of severity and artistic beauty of calligraphy.
Styles also tend to be diversified, which is of great artistic appreciation value. According to legend, Li Shu was compiled by Cheng Miao in prison at the end of Qin Dynasty, which simplified traditional Chinese characters, rounded fonts and changed strokes into straight ones. Changing "Lian Bi" into "broken pen" and changing lines into strokes makes writing more convenient. "Li Ben" is not a slave, but a small official, that is, a small official in charge of documents, so in ancient times, official script was called "Zuo Shu".
At the same time, cursive script, regular script and running script were derived, which laid the foundation for art. Official script basically evolved from seal script, mainly changing the round strokes of seal script into square folds. Because it is difficult to draw round strokes on wooden slips with pigments, the official script is written faster. Li Bian is an important calligraphy cultural event in the history of calligraphy in China.
The internal motivation of the official change is to adapt to the requirements of the social development at that time for the application of characters. "Li change is mainly manifested in two aspects: first, the change of font structure is not only the change of regular script font structure, but also the main direction of this change is simplification; The second is the change of writing style, which is not only to change the writing style of the original regular script, but also to be concise and convenient.
