Cai Jing, the envoy of Lingnan Xidao Circuit, was harsh and cruel in his administration. He used the cruel punishment of branding criminals with hot iron, and the people under his jurisdiction were very resentful of the cruel government. So the Yuzhou army expelled Cai Jing from the country. Cai Jing fled to Tengzhou. He forged the emperor's edict and the seal of the envoy to attack Yuzhou, and recruited villagers and local troops in the nearby states and counties.
