《徐霞客游记·粤西游日记六》
我先从那条向下的石瞪走，就到了向北的山麓，山麓全是空洞，像是云气喷出帷慢下覆，外边有倒立的岩石，分隔成门，排列为窗，而里面蜿蜿蜒蜒四通八达，绕着走好像走在回廊与双层通道之中，这是下洞中最幽深奇妙的地方了。
余先从其下者，则北向之麓，皆崆峒如云嘘幔覆，外有倒石，界而为门，列而为窗，而内蜿蜒旁通，绕若行廊复道，此下洞之最幽奇者也。
I first walked from that downward stony stair, and then arrived at the foothills to the north, where the foothills are all hollow, as if clouds and vapors were spewing out under the hanging curtains, where there are inverted rocks outside, dividing them into doors, arranging them into windows, while inside they are meandering and interconnected, walking around them feels like walking among covered corridors and double-layered passages, This is the most profound and marvelous place in the lower cave.
