Clerical script

The clerical script (traditional Chinese: 隸書; simplified Chinese: 隶书; pinyin: lìshū), sometimes also chancery script, is a style of Chinese writing that evolved from the late Warring States period to the Qin dynasty. It matured and became dominant in the Han dynasty, and remained in active use through the Six Dynasties period. In its development, it departed significantly from the earlier scripts in terms of graphic structures (a process known as libian), and was characterized by its rectilinearity, a trait shared with the later regular script. Although it was succeeded by the later scripts, including the regular script, the clerical script is preserved as a calligraphic practice. In Chinese calligraphy, the term clerical often refers to a specific calligraphic style that is typical of a subtype of the clerical script, the Han clerical (汉隶; 漢隸) or bafen (八分) script. This style is characterized by the squat character shapes, and its "wavy" appearance due to the thick, pronounced and slightly downward tails that are up-tilted at the ends.
