Chen Zhen (陳真; 陈真; Chén Zhēn; Can4 Zan1) is a fictional character created by Hong Kong writer Ni Kuang. First portrayed by Bruce Lee in the 1972 film Fist of Fury, the character has been the subject of numerous film and television series, including remakes and adaptations of Fist of Fury. Many notable actors, including Jet Li and Donnie Yen, have portrayed Chen Zhen on screen after Bruce Lee. Although Chen Zhen's story varies in the different remakes and adaptations, most have an ending similar to the original Fist of Fury. Chen Zhen is believed to be based on Liu Zhensheng (劉振聲), an apprentice of Huo Yuanjia, a martial artist who lived during the late Qing dynasty of China. Chen Zhen is depicted as an apprentice of the martial artist Huo Yuanjia, who founded the Chin Woo Athletic Association (also known as Chin Woo School or Jingwu School) in 1910. After Huo Yuanjia meets his demise under dubious circumstances, Chen Zhen discovers that his shih-fu was poisoned by their rivals from a Japanese dojo in Hongkou District, Shanghai. The furious apprentice seeks to bring the murderers to justice and embarks on a brutal quest to avenge Huo Yuanjia and revive his shih-fu's legacy, the "Jingwu Spirit".
