《徐霞客游记·粤西游日记十一》
走入这个洞，只见缝隙裂成石完，香烟纸雾，弥漫缭绕于洞中，可洞中无神像，外边竖着竿子，竿顶挂着旗子，辨不清这是什么洞什么神。
入其洞，则隙裂成龛，香烟纸雾，氤氲其间，而中无神像，外竖竿标旗，而不辨其为何洞何神也。
Walking into this cave, we saw that the crevices were cracked into stone, and the smoke of incense and paper was lingering in the cave, but there was no idol in the cave. Outside, there was a pole with a flag on top, but it was not clear what kind of cave or god this was.
