China has since ancient times been a united multi-ethnic country. After the foundation of the People’s Republic of China, there is a total of 56 ethnic groups officially recognized by the central government, the largest being the Han ethnic group.
The standard language in China is Mandarin Chinese, a universal language used by every ethnic group. The state council announced on February 6, 1956, that Mandarin should be promoted and supplemented the concept of mandarin: Mandarin has Beijing pronunciation as its standard pronunciation, northern dialect as its primary dialect, and the typical modern vernacular Chinese as its grammatical standard.
In addition to Mandarin, there are 80 languages in this multinational and multilingual nation. Most minorities have their languages. Even for Chinese itself, almost every region has its dialect, which can be very different from each other. Local people talk in their dialects while learning Mandarin at school.
