후조
In 324, the first real battle between Later Zhao and Han Zhao occurred at Xin'an (新安, in modern Luoyang, Henan), ushering an era in which Later Zhao and Han Zhao would continuously battle for years. In 325, their armies fought a major battle near Luoyang (which the two, as well as Jin, had fought over for months), and after some initial Han Zhao successes, Later Zhao's general Shi Hu decisively defeated and captured Han Zhao's general Liu Yue (劉岳), after Liu Yao himself encountered difficulties with his army discipline and could not come to Liu Yue's aid. Later Zhao took this opportunity to effectively take the modern central Henan, northern Jiangsu, and western Shandong under its control.
