前趙
In fall 312, Han Zhao forces, under Liu Can and Liu Yao, dealt a serious blow to the Jin general Liu Kun (劉琨) the governor of Bing Province (并州, modern northern and central Shanxi), who had been a constant threat to Han Zhao, capturing Liu Kun's headquarters at Jinyang (晉陽, in modern Taiyuan, Shanxi) and killing Liu Kun's parents. While Liu Kun was able to recapture Jinyang with the assistance of the Xianbei chief Tuoba Yilu the Duke of Dai, he would not pose a serious threat to Han Zhao from that point on.
