Han Zhao
In 324, Later Zhao and Han Zhao began actively engaging each other, and for the next several years, they would wage war against each other bitterly, fighting over both their border territory and the parts of territory near the Yellow River still under Jin control. In 325, Shi Hu would defeat the Han Zhao general Liu Yue (劉岳), seizing the entire Luoyang region, which had previously been under split Jin and Han Zhao control, for Later Zhao.
