;Chaoshan dialect is a kind of Southen Min dialect, it was separated from Fukien Southen Min dialect probably in the Tang Dynasty. Voice system of Chaoshan dialect corresponds to the Southen Min dialect by comparison. Because the Chaoshan is located in Guangdong, the Literary Pronunciation system was learned from the Guangfu, so the performance of more innovative than Fukien Southen Min dialect. Compared with Chaozhou, Fujian′s Amoy, Zhangzhou and Quanzhou is the former economic and cultural center. The core area is often large population flow and more affected by the external, resulting in faster sound changes. Most of the old voices will remain in the peripheral area, Chaoshan dialect was found to have more ancient language than Fukien Southen Min dialect. In addition to Chaoshan dialect, the western Guangdong, Hainan Island, Guangxi and other regions are also popular Southen Min dialect. After comparison, we make sure the Min dialect of West and south of the Chaoshan was under the branch of Chaoshan and Zhangzhou. The Min dialect of east and north of Zhang-Quan, is considered to be Central Min and Puxian Min Dialect, but found that the voice pattern was originally Southen Min dialect after comparison. There have been sound change because of the junction zone.
Generally, Chaoshan dialect can be divided into two kinds of definitions, the generalized Chaoshan dialect includes Chaoshan and Fulao dialect, but Fulao dialect is not included in the narrow Chaoshan dialect. After the comparison of the Fulao and other Southen Min dialect, We found the Fulao dialect is relatively close to Zhangzhou dialect. Looking at the source of immigrants, we will find that " Fulao people" were immigrants from southern Fujian in after the late Tang or Song dynasty, and the original "Holo people" came earlier. Narrow Chaoshan is usually divided into two to three small pieces, after the internal comparison, we believe that the Chaoshan dialect divided into the East and the West will be better than other ways. East Chaoshan dialect can be divided into Chaozhou voice system and Shantou voice system. West Chaoshan dialect can be divided into Jieyang voice system and Chaoyang voice system.
