Soon thereafter, Gongshan Furao (also known as Gongshan Buniu), a retainer of the Ji family, revolted and took control of the forces at Bi. He immediately launched an attack and entered the capital Lu. Earlier, Gongshan had approached Confucius to join him, which Confucius considered as he wanted the opportunity to put his principles into practice but he gave up on the idea in the end. Confucius disapproved the use of a violent revolution by principle, even though the Ji family dominated the Lu state by force for generations and had exiled the previous duke. Creel (1949) states that, unlike the rebel Yang Hu before him, Gongshan may have sought to destroy the three hereditary families and restore the power of the duke. However, Dubs (1946) is of the view that Gongshan was encouraged by Viscount Ji Huan to invade the Lu capital in an attempt to avoid dismantling the Bi fortified walls. Whatever the situation may have been, Gongshan was considered an upright man who continued to defend the state of Lu, even after he was forced to flee.
