After causing severe damage, the Japanese students leave. The Japanese students and their master retaliate by attacking Jingwu School on Suzuki's orders. The guard blows his whistle to alert the police, but the citizens who watched the whole fight help Chen to escape the park. Chen beats up the man and his friends in anger.
After the guard allows a foreigner to bring her pet dog into the park, a Japanese man approaches Chen and tells him that if he behaves like a dog, he will be allowed to go in. A Sikh guard refuses him entry, due to a posted sign that forbids dogs and Chinese in the park.
He smashes the glass on the sign and makes the students who taunted him earlier chew up the paper bearing the derogatory words, so as to make them literally "eat their words". He winds up fighting the Japanese students, defeating all of them, including their sensei, single-handedly. Shortly afterwards, Chen Zhen goes to the Hongkou dojo alone to return the sign. Chen Zhen wants to retaliate, but is prevented from doing so by Fan Junxia, the most senior student in the school. The protégé taunts the Jingwu students to fight him and promises, "I'll eat those words if any Chinese here dare to fight and defeat me". They present a sign to Jingwu School, bearing the words " Sick Man of East Asia", seemingly to insult Huo Yuanjia, describing the Chinese as "weaklings" in comparison to the Japanese. Wu En, translator and advisor for the Japanese dojo's grandmaster Hiroshi Suzuki, taunts Chen by slapping him on the cheek several times, and dares him to fight one of Suzuki's protégés. During the funeral, people from a Japanese dojo in Hongkou District arrive to taunt the Jingwu students. However, he learns that his master Huo Yuanjia has died, apparently from illness, which devastates Chen. Set in late Summer 1910 Shanghai, Chen Zhen returns to Jingwu School to marry his fiancée Yuan Li'er. It was the highest-grossing Hong Kong film up until Lee's The Way of the Dragon (1972). The film grossed an estimated US$100 million worldwide (equivalent to over $600 million adjusted for inflation), against a budget of $100,000.
It differs from other films in the genre for its historical and social references, especially to Japanese imperialism. The film touched on sensitive issues surrounding Japanese colonialism, and featured fairly realistic fight choreography for its time. The film was produced by the Orange Sky Golden Harvest film production company, still in its infancy at the time, and it was Lee's second kung fu film. Lee, who was also the film's action choreographer, plays Chen Zhen, a student of Huo Yuanjia, who fights to defend the honor of the Chinese in the face of foreign aggression, and to bring to justice those responsible for his master's death. Fist of Fury is a 1972 Hong Kong action martial arts film written and directed by Lo Wei, produced by Raymond Chow, and starring Bruce Lee in his second major role after The Big Boss (1971).
