Wenzhounese (, Wenzhounese: Iu Chiu ho), also known as Oujiang (), Tong Au () or Au Nyü (), is the language spoken in Wenzhou, the southern prefecture of Zhejiang, China. It is the most divergent division of Wu Chinese, with little to no mutual intelligibility with other Wu dialects or any other variety of Chinese. It features noticeable elements in common with Min Chinese, which is spoken to the south in Fujian. Oujiang is sometimes used as the broader term, and Wenzhou for Wenzhounese proper in a narrow sense. Given its long history and the isolation of the region in which it is spoken, Wenzhounese is so unusual in its phonology that it has the reputation of being the least comprehensible dialect for an average Mandarin speaker. It preserves a large amount of vocabulary of classical Chinese lost elsewhere, earning itself the nickname "the living fossil", and has distinct grammatical differences from Mandarin. Wenzhounese is one of five varieties of Chinese other than Standard Mandarin used for broadcasting by China Radio International, alongside Cantonese, Hokkien, Teochew, and Hakka. Wenzhounese is part of the Wu group of Chinese dialects, sharing many linguistic features with them. These are spoken over the Zhejiang and south Jiangsu provinces. Wenzhounese is seen as a typical representative of southern Wu. Wenzhounese is spoken primarily in Wenzhou and the surrounding southern portion of Zhejiang, China. To a lesser extent, it is also spoken in scattered pockets of Fujian in southeastern China. Overseas, it is spoken in increasingly larger communities in the United States in Flushing Chinatown in the Queens borough of New York City, and the Chinatowns in Brooklyn in New York City. Wenzhounese is also spoken by some Overseas Chinese communities in Europe, in particular Italy, France, and Spain. It is used more widely among the Chinese people in Italy than Mandarin,. Over 80% of the Chinese diaspora that are resident in the city of Prato, Tuscany, were born in Zhejiang Province.
