《徐霞客游记·楚游日记一》
起先是从溪口往东进去，走一里，望见一条小溪从西南的山峡中穿流出来，石崖层层横贯，对峙如门。
初随溪口东入，望西峡，石崖层亘，外束如门。
From the mouth of the creek, we went eastward at first, and after walking one li, we saw a small creek flowing out of the mountain gorge in the southwest, and the layered stone cliffs spanned horizontally and stood opposite to each other like a gate.
