分散在我国不同地域的汉语,因发展有快慢并与不同语言融合,从而形成方言。汉语产生于中原,逐步向周边扩散,长江以南原说非汉语,因历史上汉语分批南迁,分别与土著的南蛮(苗瑶)、百越(侗台)语言的不同支系结合,乃形成湘赣客语、吴闽粤语等方言。所以汉语方言可大别为两类:北方的官话和南方的非官话。 Chinese, scattered in different regions of our country, form dialects because of their speed of development and integration with different languages. Chinese was produced in the Central Plains and gradually spread to the surrounding areas. Formerly non-Chinese in the south of the Yangtze River, it was merged with the different branches of native Nanan (Miao and Yao) and Baiyue Formation of Hunan-Jiangxi Hakka, Wu and Cantonese dialects. Therefore, Chinese dialects can be divided into two categories: Mandarin in the north and unofficial in the south.
