I myself have travelled west as far as K'ung-t'ung, north past Cho-lu, east to the sea, and in the south I have sailed the Yellow and Huai Rivers. The elders and old men of these various lands frequently pointed out to me the places where the Yellow Emperor, Yao, and Shun had lived, and in these places the manners and customs seemed quite different. In general those of their accounts which do not differ from the ancient texts seem to be near to the truth.
