Overseas Chinese who are ethnically Han Chinese, such as Cantonese, Hoochew, Hokkien, Hakka or Teochew refer to themselves as (Tángrén), pronounced "tòhng yàn" in Cantonese, "toung ning" in Hoochew, "Tn̂g-lâng" in Hokkien and "tong nyin" in Hakka. Literally, it means "Tang people", a reference to Tang dynasty China when it was ruling China proper. This term is commonly used by the Cantonese, Hoochew, Hakka and Hokkien as a colloquial reference to the Chinese people and has little relevance to the ancient dynasty. For example, in the early 1850s when Chinese shops opened on Sacramento St in San Francisco, the Chinese emigrants, mainly from the Pearl River Delta west of Canton, called it "Tang People Street" () and the settlement became known as "Tang People Town" () or Chinatown, which in Cantonese is "Tong Yun Fow".
