Guizhou dialect in a broad sense includes all Chinese dialects in Guizhou, but it is geographically connected with Sichuan, and its phonetic system and vocabulary are the same as Minjiang dialect, the second largest dialect in southern Sichuan. The Minjiang River in Chishui, Xishui, Tongzi, Wuchuan, Yanhe, Yinjiang, Sinan and Dejiang counties in northern and northeastern Guizhou is often regarded as Sichuan dialect by Sichuanese. The other Guizhou dialects are not found in Sichuan except the northern Guizhou dialect distributed in Xiushan, so they are Guizhou dialects in a narrow sense, and the classification is as follows: 1. Northern Guizhou dialect: There are 27 counties and cities in northern Guizhou Province with Zunyi-Liupanshui-Bijie as the center. 2. Kungui tablets: Guiyang City-Anshun City, Guizhou Province, Southwest Guizhou Province, etc. 3. Jiang Cen Film: Zhenyuan-Cengong-Liping-Jinping-Taijiang 12 County in Qiandongnan. 4. Qiandongnan and Qiannan: Kaili-Duyun-Majiang County in southern Guizhou Province.

Because there are five small pieces of southwest mandarin in Guizhou, there are great differences, so it is nonsense to say that so-and-so is the standard pronunciation of Guizhou dialect. The small piece of Minjiang River in nine counties of northern and northeastern Guizhou retains the tone of entering the Middle Ages, with an independent tone value of 33 and a vowel of Q, which is unique in Guizhou dialect. Because of its unique pronunciation and phonology, it inherited the Cuban Shu language before the Yuan Dynasty, and some experts suggested that it should be divided into southwest mandarin and single Shu language, so it is impossible to generalize the status of Minjiang Xiaopian and the other four pieces in Guizhou. Although the other four films in Guizhou have different accents, they all conform to the tone of entering tone and belong to southwest mandarin. Among them, Jiang Cen's films have the biggest internal differences, including Miao Yao and Zhuang Dongdi; Guiyang dialect in Kungui film has lost many characteristics of Kungui film and is moving closer to the new school of Chengdu-Chongqing film. The old-school Chinese dialects in southern Guizhou and "Chuanqing people" have nasal rhyme characteristics similar to Wu dialect and Jianghuai Mandarin, such as ian changing into ie, which coincides with the legend that the ancestors of Han people came from Nanjing and other Jianghuai areas. The Qiandongnan dialect in Guizhou has a local Miao accent, commonly known as "Miao sound". For example, there are Miao sounds in Majiang dialect, Leishan dialect and Kaili dialect.
