Promotion of Standard Chinese

The promotion of Standard Chinese, abbreviated as Tuipu (推普), is a campaign by the government of the People's Republic of China, with the stated goal being to facilitate easier communication throughout the country, which has historically spoken many mutually unintelligible varieties of Chinese, as well as non-Sinitic languages. Currently, the promotion of Standard Chinese is organized by the State Language Work Committee, a regulatory agency within the Chinese government.
