The Clerical script (traditional Chinese: 隸書; simplified Chinese: 隶书; pinyin: lìshū) is an
archaic style of Chinese calligraphy. The clerical script was first used during the Han dynasty
and has lasted up to the present
In its development, it departed significantly from the earlier scripts in terms of graphic
structures (a process named libian, or "clerical change"), and was characterized by its
rectilinearity, a trait shared with the later regular script.
