Gan, Gann, Kan, or Jiangxihua, is a variety of Chinese spoken by about 22 million people mainly in the Chinese province of Jiangxi, and also in eastern Hunan, southeastern Hubei, southwestern Anhui, and northwestern Fujian provinces. It has some mutual intelligibility with Mandarin and Wú.
Like all other varieties of Chinese, there is a large amount of mutual unintelligibility between Gan Chinese and other varieties. Within the variation of Chinese dialects, Gan has more similarities with Mandarin than with Yue or Min. However, Gan clusters more with Xiang than Mandarin. The Pinfa romanization system was developed by Dr C. F. Lau, a.k.a. Liu Zin Fad for Hakka, and was later adapted for Gan and Xiang.
There are significant differences within the Gan-speaking region. For example, in Anfu county, which was categorized as Ji-Cha, there are two main varieties, called Nanxiang Hua (Southern region) and Baixiang Hua (Northern region). People from one region cannot even understand people from the other region if they were not well educated or exposed to the other.
