Teochew Min

Teochew, also known as Swatow or Teo-Swa after its two best-known dialects, is a Southern Min language spoken by the Teochew people in the Chaoshan region of eastern Guangdong and by their diaspora around the world. It is sometimes referred to as Chiuchow, its Cantonese rendering, due to English romanization by colonial officials and explorers. It is closely related to Hokkien, as it shares some cognates and phonology with Hokkien.

Teochew preserves many Old Chinese pronunciations and vocabulary that have been lost in some of the other modern varieties of Chinese. As such, Teochew is described as one of the most conservative Chinese languages.
