《水经注·卷三十六》
此乡方圆百里，现在夷人聚居在这里，却不敢定居放牧；有罪的人逃到野外，要抓他的人如不逼得很紧，能够藏身三年，抓他不到，大家也就宽有了他，以为他得到大禹神灵的保佑。
今夷人共营之，地方百里，不敢居牧。有罪逃野，捕之者不逼，能藏三年，不为人得，则共原之，言大禹之神所祐之也。
This village, 100 square li, is now inhabited by barbarians, yet they dare not settle down for grazing; criminals who escape into the wilderness, if their captors do not chase them tightly, can hide for 3 years, and if they cannot be captured, then everyone will let them be, believing that they received protection from Dayu’s divine spirit.
