Zhu Fu

Zhu Fu is a fictional character in Water Margin, one of the Four Great Classical Novels of Chinese literature. Nicknamed "Sneering Tiger", he ranks 93rd of the 108 Stars of Destiny and 57th of the 72 Earthly Fiends.

Zhu Fu and his elder brother, Zhu Gui, serve as a spies for the outlaw band based in Liangshan Marsh. Both of them disguise themselves and pretend to operate taverns near Liangshan to gather intelligence from travellers. In his early days, he was a martial arts apprentice of Li Yun, who works as a chief constable in his hometown of Yishui County.

When Li Kui goes home to fetch his mother to Liangshan, Song Jiang feels worried that Li Kui's fiery temper will get him into trouble so he asks Zhu Gui to secretly watch over Li Kui. As Song Jiang expected, Li Kui runs into trouble and falls into a trap set by a greedy squire. The local magistrate sends Li Yun to lead soldiers to escort Li Kui to the county office. Zhu Gui and Zhu Fu pretend to congratulate Li Yun on his success in capturing a wanted outlaw, and serve Li Yun and his soldiers food and drinks spiked with drugs that will make them unconscious. When Li Yun and his men are out cold after unwarily consuming the food and drinks, the Zhu brothers free Li Kui, who kills all the soldiers. Li Yun regains consciousness later, catches up with them, and fights with Li Kui. Zhu Fu stops the fight and manages to convince Li Yun to join the outlaw band at Liangshan.

Zhu Fu is put in charge of brewing alcoholic drinks for Liangshan after the Grand Assembly of the 108 Stars of Destiny. He follows the Liangshan heroes on their campaigns against the Liao invaders and rebel forces on Song territory after they received amnesty from Emperor Huizong.

During the campaign against Fang La's rebel forces, Zhu Fu remains in Hangzhou to take care of Zhu Gui, who has fallen sick, and does not participate in the subsequent battles. The Zhu brothers both die of illness before the Liangshan heroes claim victory over Fang La.
