《水经注·卷十七》
下马一直朝山洞攀登约百余初，石径弯弯曲曲，勉强可容一人通行。僵尸倚着洞壁，尸骸还完好，只是没有皮肤头发而已。
释鞍就穴直上，可百余仞，石路逶迤，劣通单步，僵尸倚窟，枯骨尚全，唯无肤发而已。
Keep dismounting for about 100 meters and climbing towards the cave. The stone path is winding and can barely accommodate one person. The zombie is leaning against the wall of the cave with its skeleton intact, but without skin and hair.
