 Emperor Zhaozong, in flight, issued an edict to him and Wang Ke, ordering them to attack Wang Xingyu, while ordering Zhang Fan (張鐇) the military governor of Zhangyi Circuit (彰義, headquartered in modern Pingliang, Gansu) to block off any forces from Fengxiang.Li Keyong then attacked Han at his headquarters at Hua Prefecture (華州, in modern Weinan) and was poised to take it, when news arrived that Wang Xingyu and Li Maozhen had launched their own troops and were planning to seize the emperor.Li Keyong thus lifted the siege of Hua Prefecture and advanced toward Chang'an.
