《徐霞客游记·粤西游日记六》
天晚了急忙赶路，暂且留着作为日后游览的地方。共行二里，往南走上大道，回头望西面大路和在南边夹住道路的山，上面有一个洞穴东西两头穿空，也与佛子岩两头穿通的岩洞无异，都留作以后游览之地，来不及进去。
共二里，南出大道，回顾其西路南夹道之山，上有一窍东西透空，亦与佛子穿岩无异，俱留为后游，不暇执途人而问。
It was getting late, so we hurried on our way, and temporarily left this place for a future visit. We traveled for two li, and took the main road south. Looking back to the west, we saw a cave with openings on both the east and west sides on the mountain that flanked the road to the south, similar to the cave that goes through both sides of Fozizyan. We plan to visit it later, but we don't have time to go in now.
