Chinese numerals are words and characters used to denote numbers in written Chinese. Speakers of Chinese languages use three written numeral systems: the international system of Arabic numerals, and two indigenous systems ('small writing' 小写, and 'big writing' 大写). The more familiar indigenous system is based on Chinese characters that correspond to numerals in the spoken language. These may be shared with other languages of the Chinese cultural sphere such as Korean, Japanese, and Vietnamese.
