 The international (English) title of this film was "The Big Boss".  In the United States the English dubbed version was originally to be  released under the title "The Chinese Connection", a play on the  title of the highly popular film  _French Connection, The (1971)_ (qv). For some reason the title was  changed to "Fists of Fury". As a result, to avoid confusion with  Bruce Lee (I) (qv)s following film _Jing wu men (1972)_ (qv)  (known elsewhere in the world as "Fist of Fury"), the latter films  title for its U.S. release became first "The Iron Hand" and then  "The Chinese Connection".
