The Number Four Boss of the Hónghuá Huì comes from Kwangtung Province. Due to injuries he suffered at the fists of Yán Wáng (Kenshirō Kasumi), he is wheelchair-bound and must wear a metal contraption with a crank to raise and lower his head. Jumpy and triggerhappy, he'll shoot anything that bothers him. A slovenly womanizer, Wu desired Pan Guanglin's actress girlfriend Yáng Měi-Yù. The insanely jealous Wu held Pan in his dungeon, intending to use him as the "tiger-meat" in his Cantonese "Dragon-Tiger Stew". Wu never got the chance, because Kenshiro knocked Wu into his own boiling cauldron, killing him.
