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.
