Chinese (simplified Chinese: 汉语; traditional Chinese: 漢語; pinyin: Hànyǔ; literally: "Han language"; or Chinese: 中文; pinyin: Zhōngwén; literally: "Chinese writing") is a group of related, but in many cases not mutually intelligible, language varieties, forming the Sinitic branch of the Sino-Tibetan language family. Chinese is spoken by the Han majority and many minority ethnic groups in China. About 1.2 billion people (around 16% of the world's population) speak some form of Chinese as their first language.
Simplified Chinese characters (简化字; jiǎnhuàzì) are standardized Chinese characters for use in mainland China. Along with traditional Chinese characters, they are one of the two standard character sets of the contemporary Chinese written language. They are officially used in Singapore and the People's Republic of China where the government has promoted them for use in printing since the 1950s and 1960s to encourage literacy.
