《资治通鉴·晋纪·晋纪十》
刘琨听说后，向东在常山及中山聚集军队，派部将郝诜、张乔带兵阻击刘粲，并且派使者向代公拓跋猗卢请求救援。
琨闻之，东出，收兵于常山及中山，使其将郝诜、张乔将兵拒粲，且遣使求救于代公猗卢。
When Liu Kun heard about it, he gathered his army in Changshan and Zhongshan in the east, sent his generals Hao Shen and Zhang Qiao to lead troops to intercept Liu Can, and sent messengers to Dai Gong Tuoba Yilu for help.
