The Khitan small script was one of two writing systems used for the now-extinct Khitan language. It was used during the 10th–12th century by the Khitan people, who had created the Liao Empire in present-day northeastern China. In addition to the small script, the Khitans simultaneously also used a functionally independent writing system known as the Khitan large script. Both Khitan scripts continued to be in use to some extent by the Jurchens for several decades after the fall of the Liao dynasty, until the Jurchens fully switched to a script of their own. Examples of the scripts appeared most often on epitaphs and monuments, although other fragments sometimes surface.

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.
