The Han people have their own spoken and written languages, namely Chinese. It is the most commonly used language in China, and one of the most commonly used languages in the world. All China's 55 minority peoples have their own languages except the Hui and Manchu who use Chinese; 22 of them have their own scripts, in which 28 languages are written. Nowadays, school classes in predominantly ethnic minority areas are taught in the local language, using local-language textbooks. Meanwhile courses are also set up to popularize Putonghua Chinese - the official national language - which is commonly used throughout the country.
