Ningdu County,under the jurisdiction of Ganzhou City,is located in the southeast of Jiangxi Province and the north of Ganzhou City.It has jurisdiction over 24 townships and 299 administrative villages with a population of more than 900000.Although the territory belongs to the Hakka dialect,due to the large number of townships,and the environmental gap between the North and the South,there are also significant differences in the vocabulary of their dialects.In recent years,a comprehensive survey has been con-ducted on their townships,recording not only the phonetic sounds,but also the dialect vocabulary,aiming to explore whether there are differences in the dialect pronunciation and vocabulary within the region.The survey shows that there are differences not only between the North and the south,but also between the dialect areas,even within the same area.The content of the article is a reflection of the vocabulary differences.Through the investigation of Hakka vocabulary,the conclusion is drawn that:first,the forms of various words are diverse;second,the geographical distribution of some words is relatively obvious;third,the consistency of dialect words is higher in the north than the south.
