The Legend of Deng Fei in Water Margin
Deng Fei is an intriguing martial figure in the classical Chinese epic Water Margin. Known by the moniker “Fire-Eyed Suan Ni”—referencing a fearsome, lion-like mythological creature—he earned this title due to his naturally bloodshot eyes and ferocious temperament in melee combat. As the Earth Ax Star, seated 49th among the 108 Stars of Destiny, he is distinguished by his mastery of a heavy iron chain weapon, which he used with lethal skill to ensnare enemy blades and break defensive formations.
Origins at Yinma Mountain
Before pledging his allegiance to the Liangshan cause during the tumultuous Northern Song Dynasty, he operated as a prominent bandit chieftain at Yinma Mountain alongside the upright scholar Pei Xuan and the shipwright Meng Kang. When the wandering chieftain Dai Zong passed through their territory, the trio resolved to merge their stronghold with the Liangshan brotherhood. Throughout his tenure at the mountain fortress, Deng Fei served as an active leader in the vanguard cavalry, participating in major campaigns against corrupt imperial forces and regional warlords.
