《太平广记·卷二百一十七·卜筮二》
祷告完了，改用龟卜，砍一块龟板烧灼，说：你们问卜的这个人，在龟卜的显象中象似病了却没有病，好象死了却没有死。
祝毕。拂龟改灼。复曰：君所卜行人，兆中如病非病，如死非死。
After praying, he switched to turtle divination, cutting out a turtle shell and burning it, saying: This person you are asking about, in the manifestation of turtle divination, seems like he is sick but not sick, like he is dead but not dead.
