Gongsun Sheng
The hijackers eventually number seven with the participation of Wu Yong, Gongsun Sheng and the Ruan Brothers. With the help of Bai Sheng, who poses as a wine seller, they succeed in seizing the valuables at the Yellow Mud Ridge by drugging the escorts of the gifts led by Yang Zhi. But the authorities soon track down essential clues and the magistrate of Yuncheng sends Zhu Tong and Lei Heng to seize Chao Gai at his house. Both want to let Chao go but they hide the intention from each other. Zhu Tong prevails on Lei to enter Chao's house through the front door while he himself guards the back knowing Chao would come that way. Lei nevertheless makes noise to warn Chao as his men intrude into the house. As expected by Zhu, Chao and his gang leave by the back and escape with his help.
