In Chinese culture, the word tong means "hall" or "gathering place". In North America, a tong (Chinese: 堂; pinyin: táng; Cantonese Yale: tong; literally: "hall") is a type of organization found among Chinese living in the United States and Canada. These organizations are described as secret societies or sworn brotherhoods and are often tied to criminal activity. Today in most American Chinatowns, if one can read Chinese, one can find clearly marked tong halls, many of which have had affiliations with Chinese crime gangs, especially in the 1990s.
