Dragon Fist (simplified Chinese: 龙拳; traditional Chinese: 龍拳, also known as Dangsang Martial Arts or The Wild Big Boss)[2] is a 1979 Hong Kong martial arts film directed by Lo Wei, who also Hsu Li-hwa.

The film stars Jackie Chan, Nora Miao, James Tien, Yen Shi-kwan, Eagle Han-ying, and Wu Wen-sau.

Tang and the one-legged master join forces to defeat the evil lord who poisoned San-thye's widow.

Like Chan's Spiritual Kung Fu, Dragon Fist was filmed in South Korea in early 1978 but was unable to be released or produced because the studio went bankrupt and was running out of money.

As a result, both Lo Wei productions only had cost-cutting measures after Chan returned from his loan deal with Seasonal Films, where he made Snake in the Eagle's Shadow and Drunken Master alongside director Yuen Woo-ping.
