Briefly describe the concept of homonym in modern Han nationality, and talk about the dialects of Chinese in Han dynasty.

Homophones in modern Chinese refer to Putonghua with Beijing pronunciation as the standard, northern dialect as the basic dialect, and typical modern vernacular as the grammatical norm.

2 reasons for formation

Homophones in modern Chinese are formed on the basis of northern dialects. In the process of its formation, Beijing dialect occupies a special position. As early as the Tang Dynasty, Beijing was already a military center in the north. Beijing was the capital of Liao, Jin, Yuan, Ming and Qing dynasties. For nearly a thousand years, Beijing has been the political, economic and cultural center of our country. Therefore, the influence of Beijing dialect is growing. On the one hand, as the common language of the government, it has spread all over the country and developed into "Mandarin". On the other hand, vernacular literature works are more influenced by Beijing dialect and gradually develop into representative and even exemplary written language.

At the beginning of the 20th century, especially after the May 4th Movement, the "vernacular movement" shook the dominant position of classical Chinese. At the same time, the development of "Putonghua Movement" has promoted Beijing pronunciation to become the standard pronunciation of the national language. Under the mutual promotion and influence of these two movements, spoken and written languages are close to each other, gradually forming modern Chinese, that is, Putonghua.
