The Sui dynasty general in command of cavalry Dug Gu Wudi trusted Wang Shichong. Dug Gu Wudi's younger brother, Daguan of the judicial administration, Dug Gu Ji; the chief of the Department of Justice, Yang Gongshen; the former county clerk of Bohai, Sun Shixiao; the general in command of infantry Liu Xiaoyuan, Li Jian, and Cui Xiaoren, planned to lure Tang troops to come, so they let Cui Xiaoren tell Dug Gu Wudi: "Wang Shichong only tries to win over his subordinates with intimate and personal sentiment, but in fact he is stingy, mean, greedy and cruel, and takes no account of his kin and former friends, so how can he achieve great things!"
