Different dialects of Gan Chinese exist; the Nanchang dialect is usually taken as representative of all other dialects.
3. Kejia (Hakka)
Hakka is a variety of Chinese Languages, spoken natively by the Hakka people throughout Southern China,Taiwan, Hong Kong, Macau, and throughout the dispersed areas of East Asia, Southeast Asia.
Due to its main usage in scattered & isolated regions where communication is limited to the local area, Hakka has developed numerous varieties, It is spoken in different provinces, like Guangdong, Guangxi, Hainan, Fujian, Sichuan, Hunan, Jiangxi, and Guizhou provinces, & Hong Kong, Taiwan, Singapore, Malaysia, and Indonesia. Hakka do not mutually relate with Mandarin Chinese or other branches of Chinese Language, and it contains very few mutual varieties.
It is most closely related to Gan. A possibility is that the similarities are just a result of shared aerial features. and in overseas Chinese communities around the world.
Min dialect and types of Min Chinese are spoken among 75 million people mainly in Fujian province in China, and also in some parts of Jiangsu, Zhejiang, Jiangxi, Guangdong, Hainan, and Guangxi, as well as in some other parts of Southeast Asia, and especially in New York City (USA).
The Classical Chinese name for Fujian, Min comes from the Kingdom of Minyue which was located in what is now Fujian province between about 334-110 BC. The name Min was possibly an ethnic name.
Varieties of Min are divided according to the mutual relatability of five to nine separate groups. A distinction is made between the Inland & Coastal Min varieties.
Wu dialect of Chinese is mainly spoken in provinces like Shanghai, Zhejiang and southeastern Jiangsu by more than 8% (almost 90 million) of the population of China at the turn of the 21st century.
The Wu language originally started to spread from Suzhou province, which has been a cultural center since the 5th century BC, so the Suzhou variety of Wu dialect is said to be traditionally most prestigious among all other varieties. After Shanghai gained economic dominance & became an important metropolitan area from Central China, Wu is also termed as Shanghainese by non-specialists. Scholars prefer to use the term Wu Chinese.
Wu is different from Modern Standard Chinese Language in preserving the initial voiced stops (sounds formed with complete closure within the vocal tract) and in using seven or eight tones to distinguish meanings between words or word elements that have an equivalent series of consonants and vowels (Modern Standard Chinese use four tones only for such purposes) Like Modern Standard Chinese and therefore the Mandarin language of northern China, the Wu language has lost most of the Ancient Chinese final consonants.
Xiang (also known as Hunanese) is spoken mainly in the province of Hunan in China, especially in the cities of Zhuzhou, Yiyang, Xiangtan, Changsha, Loudi, Shaoyang, and Hengyang. In 2017 around 37 million people used to speak Xiang Chinese Language.
Xiang is divided into two distinct varieties:
Changsha / Old Xiang, is spoken in the southern parts of the Xiang-speaking areas,
Loudi / New Xiang: can be heard in the northern Xiang-speaking area and which is influenced by Mandarin.
Xiang Chinese Language is Romanized in Pinfa romanization system
The Pinfa romanization system was developed by Dr. C. F. Lau, a.k.a. Liu Zin Fad (劉鎮發) for Hakka Chinese, which was later adapted by Xiang and Gan.
7. Yue or Cantonese
Yue or Cantonese is a variety of Chinese languages mainly spoken in Guangxi, Hong Kong, Guangdong, Macau & other areas of southern China by more than 55 million people. There are also a notable number of Yue-speaking communities in overseas China, Like Southeast Asia, Canada, Australia, the UK, and the USA (more or less 20 million).
Yue Chinese dialect is said to be closer to the older forms of Chinese Language, particularly that of the Tang Dynasty (618-907 AD), than Mandarin, as is some of its grammar. Many old poems that do rhyme when read in the Yue dialect do not rhyme in the Mandarin dialect. It is believed that due to the southern region’s relative remoteness and the lack of efficient communications and commutation, the Tang variety survived almost unchanged.
