AH Fong had portrait studios in Shanghai and in Wei-hai-wei (Weihai), and was active in the 1930s.  Ah Fong is not to be confused with Afong, which was the professional name of Lai Fong (c.1839-1890), the pre-eminent nineteenth-century Chinese photographer, who founded the Afong Studio in Hong Kong (active 1870-1940s).  A book of photographs entitled The Sino-Japanese Hostilities Shanghai 1937 was sold by 'Ah Fongs Photographers', Nanking Road, Shanghai, although the photographs therein were apparently taken by two photographers identified only as: “S.S.” and S.C.S.  See Kn01-210.
