The clerical script, 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, and was characterized by its rectilinearity, a trait shared with the later regular script.

Traditional Chinese characters are a standard set of Chinese character forms used to write Chinese languages. In Taiwan, the set of traditional characters is regulated by the Ministry of Education and standardized in the Standard Form of National Characters. These forms were predominant in written Chinese until the middle of the 20th century, when various countries that use Chinese characters began standardizing simplified sets of characters, often with characters that existed before as well-known variants of the predominant forms.
