《搜神记·卷十三》
魏文帝认为火的性质严酷猛烈，不含有生命的元气，便把这东西写进了《典论》，说明这是不可能有的事，来杜绝那些聪明人的听传。
文帝以为火性酷裂，无含生之气，着之典论，明其不然之事，绝智者之听。
Emperor Wen of Wei believed that the nature of fire was harsh and fierce and did not contain the animating force needed for life, and so he wrote about this thing in the " 典论" (Discourse on Literature), saying that it was impossible for it to exist, in order to stop intelligent people from believing the rumors.
