Standard Chinese, often called Mandarin, is the official standard language of China and Taiwan, and one of the four official languages of Singapore (where it is called "Huáyŭ" / or simply Chinese). Standard Chinese is based on the Beijing dialect, the dialect of Mandarin as spoken in Beijing. The governments of both China and Taiwan intend for speakers of all Chinese speech varieties to use it as a common language of communication. Therefore, it is used in government agencies, in the media, and as a language of instruction in schools.
