《搜神记·卷六》
魏齐王嘉平初年，白马河出现怪马，那马夜间经过官府的马厩旁嘶叫，群马都应和着嘶叫。第二天，人们看见它的脚印象斗斛一样大，延绵几里，仍然回到白马河里去了。
魏齐王嘉平初，白马河出妖马，夜过官牧边鸣呼，众马皆应；明日，见其迹，大如斛，行数里，还入河。
At the beginning of the first year of King Qiwang of Wei, a strange horse appeared in the Baima River. The horse neighed at the stables of the government office at night, and the horses all neighed in response. The next day, people saw its footprints as big as the buckets and pecks, extending for several miles, and it returned to the Baima River.
