《水经注·卷十二》
洞里的水冬暖夏凉，春秋季节洞内有白鱼游出，几天后又游回洞内，有人捕到这种鱼吃过，异常鲜美，大概也是丙穴嘉鱼一类。
其水夏冷冬温，春秋有白鱼出穴，数日而返，人有采捕食者，美珍常味，盖亦丙穴嘉鱼之类也。
The water in the cave is warm in winter and cool in summer. During spring and autumn, white fish swim out from the cave. After a few days, they swim back to the cave. Those who have caught and eaten such fish said that the fish is extremely delicious. It is probably a type of Jia Fish in Ningxue.
