In Cantonese-speaking areas of Guangdong and Guangxi (parts of central and western Guangdong and parts of southern Guangxi, except the Pearl River Delta), Hakka-speaking areas of Guangdong (parts of eastern Guangdong, southern Guangdong, northern Guangdong and western Guangdong, except the Pearl River Delta) and Min-speaking areas of Guangdong (southeastern Guangdong and southwestern Guangdong), vernacular is a general term for local Cantonese, especially in Guangxi, Cantonese users only have the concept of vernacular without addressing Cantonese.
Address of Cantonese dialect: In the Pearl River Delta region, due to the strong influence of Guangzhou, vernacular is the address of Guangzhou dialect in Cantonese. Other indigenous Cantonese in the Pearl River Delta is usually called vernacular to distinguish it from local Cantonese and Hakka dialect.
Vernacular is relative to Cantonese and has nothing to do with other languages. In Guangdong, it can be divided into Guangfu dialect, Hakka dialect and Chaozhou dialect (there was also Hainan dialect before), and there are many places and people who speak Guangfu dialect. Guangfu dialect is represented by Guangzhou dialect, as opposed to Hakka dialect, Chaozhou dialect and Hainan dialect. The so-called "white" means listening, understanding and learning.
