Among the major dialects of modern Chinese in China, the northern dialect can be regarded as ancient Chinese developed in the vast northern areas for thousands of years, while the southern dialect was gradually formed when the northern residents moved south in history. The northern Han people went south several times on a large scale, bringing ancient northern Chinese in different periods, spreading to various regions in the south of the Yangtze River, and gradually forming six dialects that are obviously different from each other.
