《太平广记·卷二百一十五·算术》
马融果然用式这种卜具推算出他离去的方位，带领人去追杀郑玄。看见郑玄后，对跟他一起来追杀郑玄的人说：郑玄在土下水上而依靠着木，这回他必定得死。
融果转式逐之。告左右曰：玄在土下水上而据木，此必死矣。
Ma Rong really used this kind of divination tool to calculate the direction of his departure, and led people to chase and kill Zheng Xuan. After seeing Zheng Xuan, he said to the people who came with him to chase and kill Zheng Xuan: Zheng Xuan is under the soil and water and relies on wood. This time he will definitely die.
