《徐霞客游记·滇游日记十一》
我顺间隙坠下，看到有小水从后壁上滴滴答答地淋下来，到底部而水不见了，黑暗的地方也逐渐明亮，有个砍柴人见我进洞，站在外洞等着，等我出洞后才离去。
坠隙而下，见有小水自后壁滴沥而下，至底而水不见。黑处亦渐明。有樵者见余入，驻外洞待之，候出乃去。
I fell into the crack and saw a little water dripping from the back wall. The water disappeared at the bottom, while the dark place gradually became bright. A woodcutter saw me entering the cave and waited at the outer cave before leaving when I came out.
