Wuwei, Gansu
After his victory over Chen, Liu Yao continued west and attacked the Jin vassal Former Liang, crushing all bases that Former Liang had east of the Yellow River. He declared that he would next cross the Yellow River and head for the Former Liang capital Guzang (姑臧, in modern Wuwei, Gansu), but instead was intending to intimidate the Former Liang leader Zhang Mao (then carrying the Jin-created title Duke of Xiping) into submission. Zhang was indeed intimidated and submitted to Han Zhao suzerainty. Liu Yao created him the Prince of Liang.
