《徐霞客游记·粤西游日记十二》
到了这里就见到弯弯曲曲四通八达的旁洞，既极其高大，又多环绕曲折，既空旷豁达，又幽雅奇绝，我所观赏过的旁通的胜景，这里是最好的了。
至此则兹洞之旁通曲达，既极崇宏，复多曲折，既饶旷达，复备幽奇，余所观旁穿之胜，此为最矣。
When we got here, we saw winding and crisscrossing side caves. They were not only extremely tall but also had many circles and twists. They were both vast and open, and secluded and magnificent. Of all the beautiful scenery in the side passages that I have seen, this is the best.
