蔡京
Bai Sheng once received help from Chao Gai, the headman of Dongxi Village in Yuncheng County. When Chao and his six confederates plan to seize valuables in transportation to Grand Tutor Cai Jing in the imperial capital Dongjing, Chao suggests using Bai's home as their base as it is not far from Yellow Mud Ridge, where they would stage the hijack. Wu Yong, the strategist of the gang, suggests roping Bai into their plan.
