《徐霞客游记·粤西游日记十七》
共行二里，见灵寿大溪已向东流去，不能阻挡我了；可西山夹谷中，又有一条小溪从西流来注入灵寿溪，溪上有坝可涉过去。
共二里，见灵寿大溪已东去，不能为余阻；而西山夹中，又有一小溪西来注之，其上有堰可涉。
We walked for two miles, and saw that the Lingshou Stream was already flowing to the east, and could not block me; but in the valley between the western mountains, there was another small stream flowing in from the west into the Lingshou Stream, and there was a dam on the stream that could be waded through.
