《徐霞客游记·粤西游日记七》
原来此洞与山南面的黄鹏岩正好南北相对，可南边的层层叠叠，轩敞明朗，消愁恰神，可以长时间托身；北边的却一重重隐秘幽深，艰险难行，惊心触目，只适宜作短暂的游览。
盖此洞与山南之黄鹏正南北相当，而南则层叠轩朗，涤虑怡神，可以久托；北则重嫱险巇，骇心恫目，所宜暂游。
It turns out that this cave is exactly in the south-north direction with the Huangpeng Rock on the south side of the mountain, which is open and bright and makes people feel relaxed and happy, and one can rest here for a long time; but the north side is hidden, deep, difficult to walk, and frightening, which is good for a short visit only.
