 In summer 534, Emperor Xiaowu prepared his troops and, believing he could catch Gao by surprise, issued secret edits to Gao pretending that he was suspecting Yuwen and Heba Sheng of rebellion and planning to attack them with Gao.Gao saw through Emperor Xiaowu's plot, however, and instead marched toward Luoyang.Wang Sizheng, believing that the imperial troops were not strong enough to resist Gao's, suggested Emperor Xiaowu to flee to Yuwen's territory, and Emperor Xiaowu decided to do so, rejecting Husi Chun's offer to take one final stand at Luoyang, particularly when Heba Sheng failed to come to the emperor's aid and when Yuwen's troops failed to arrive quickly.
