Fuzhou, also known as Fuzhouhua or Foochow, is a norhern Min language of northern and central Fujian Province in China. As the most important language of the northern branch of Mn languages, it is unintelligible to other Min languages in the province, let alone to speakers of other Sinitic languages. Fuzhou is mainly spoken in the City of Fuzhou and adjacent counties such as Minqing, Lianjiang, Minhou, Changle, Yongtai and Fuqing.
Fuzhou is also widely spoken overseas in countries such as Malaysia and Indonesia. The city of Sibu in Malaysia is called "New Fuzhou" due to the influx of Chinese immigrants from Fuzhou region in the early 1900s. The language has spread to the USA, UK, Australia and Japan as a result of immigration in recent decades.
Interestingly enough, with millions of speakers home and overseas, Fuzhou is considered by some to be the most endangered metropolitan southern Sinitic languages since few youngsters in Fuzhou can converse in Fuzhou due to decades of discouragement and ban from the government.
