Bai Sheng, who lives with his wife in Anle Village (安樂村) in Yuncheng prefecture, Shandong, is nicknamed "Daylight Rat" because he is a do-nothing who spends most of his time on gambling.

Bai crosses the ridge carrying the buckets suspended on a pole on the day the soldiers, disguised as merchants, come by its top and take a rest in a grove as the weather is terribly hot.

As the "date traders" have drunk from both buckets with no seeming ill-effects, Yang Zhi grudgingly gives in to his men's pleas and allows them to buy the remaining wine.

Grand Secretary Liang Shijie, who is also the governor of Daming prefecture, is mad over the loss of the valuables, which are his birthday gifts to his father-in-law Cai Jing.

He Qing, He Tao's brother, has run into Cao Gai's group shortly before the hijack in an inn near Yellow Mud Ridge and was surprised to see the village headman posing as a trader.

Song Jiang, a clerk of Yuncheng's magistrate, is shocked when told by He Tao that Chao Gai has been identified as the mastermind of the Yellow Mud Ridge robbery.

After Chao is elected leader of Liangshan, replacing its original chief Wang Lun who was killed by Lin Chong, he sends men to bribe the prison guards at Jizhou to be lax in their watch over Bai Sheng.

He participates in the campaigns against the Liao invaders and rebel forces in Song territory following amnesty from Emperor Huizong for Liangshan.
