《徐霞客游记·粤西游日记十六》
但是私下盘算岩洞中有遗弃的建筑物，可以造小木筏浮水进去，但木料巨大不能独自移动，还将与参慧谋划这事。
然窃计岩中有遗构，可以结桴ú小筏浮水，但木巨不能自移，还将与参慧图之。
But privately, I thought that there were abandoned buildings in the cave, and I could build a small raft to float in it, but the wood was large and could not be moved alone. I would discuss this matter with Shan Hui.
