Guwutu, according to Zuo Zhuan, described him a "wolf poppy with a savage heart"(狼子野心) and believed that Yuejiao will bring disasters to the Ruo'ao clan.
Although king Zhuang soon appointed Yuejiao as the successor of Ban, Wei Jia was given the post of Sima, the supreme military commander of Chu.
Yuejiao reacted to this predicament by imprisoning Wei Jia in Liaoyang (Today's Nanyang, Henan province) and killing him.
He then organized his troops in Zhengye (Today's Xinye) and openly started an armed rebellion against king Zhuang of Chu in 605 BCE.
[6] Yuejiao's son Dou Benhuang (鬭贲皇) fled to the state of Jin and would later avenge his father's death in the battle of Yanling.
