It developed from ancient Chinese and modern Chinese. In other words, modern Chinese is the predecessor of modern Chinese, ancient Chinese is the origin of modern Chinese, and modern and ancient Chinese are two important stages of development. With these two long and important stages of development, we have a wonderful and rich modern Chinese. This sentence points out the scope and object of Chinese. Modern Chinese has two meanings: in a narrow sense, it refers to Putonghua with Beijing pronunciation as the standard, northern dialect as the basic dialect and typical modern vernacular as the grammatical norm, and in a broad sense, it includes Putonghua and various dialects. Chinese phonetics, vocabulary and grammar usually refer to Mandarin.

Chinese dialects are very complicated, which can be roughly divided into two categories: Mandarin areas and non-Mandarin areas. Northern dialect, also known as Putonghua, is the basis of the common language of the Han nationality (Putonghua). It is not only distributed in the area north of the Yangtze River where Han people live in concentrated communities, but also in some areas south of the Yangtze River, including Sichuan, Yunnan and Guizhou provinces and most parts of Hubei (except the southeast), northwestern Hunan, Nanjing and Zhenjiang.

Unofficial dialects include Wu dialect, Cantonese, Xiang dialect, Min dialect, Gan dialect and Hakka dialect.

There are two different forms of modern Chinese: spoken language and written language.

Spoken language is the language that people use orally, which has the style of spoken language. But it is fleeting and cannot be passed down for a long time. Spoken English is characterized by kindness and naturalness, short sentences and frequent omissions.
