Zhu Wu was from Dingyuan, and became a bandit at Shaohua Mountain along with Chen Da and Yang Chun. He was born with blazing eyes, a handsome face and a long beard. He donned a Taoist's garments, and carried a fan similar to Zhuge Liang's. He used a pair of swords in combat, with a skill no other could match. Besides, he was also well-versed in the art of war and was full of stratagems, thus he earned the nickname 'Resourceful Strategist' (神机军师).
