Joe Boys (also Chung Ching Yee, Chinese: 忠精義; pinyin: Zhōngjīngyì; Cantonese: Jung Jing Yi) was a Chinese youth gang founded in the 1960s in San Francisco's Chinatown. Joe Boys was originally known as "Joe Fong Boys", after its founder Joe Fong. Fong was a former member of Wah Ching.
Author Bill Lee, a former Joe Boys gang member, wrote extensively of his life's involvement in the Chinese criminal underworld, and the gang's history in his book Chinese Playground: A Memoir. Joe Boys gained further notoriety after the Golden Dragon massacre which stemmed over the sale of fire crackers in china town.
Since the Golden Dragon Massacre, the Chung Ching Yee has disbanded due to police pressure "Gang Task Force" in the San Francisco Chinatown area. Off shoots of the Wah Ching still exist today.
