《徐霞客游记·滇游日记十九》
越往东越陡，我登上崖端俯瞰，下面就是束身峡，往东到曹溪寺后的东峰，以前从崖下升登，如今登临崖上，东峰那一带，从崖底并立而上，相距一丈多，而其中有一条山脉连接，像拇指一样，可以坠下坳后登上山顶。
愈东愈甚，余凌其端瞰之，其下即束身峡，东抵曹溪后东峰，向跻其下，今临其上，东峰一片，自崖底并立而上，相距丈余，而中有一脉联属，若拇指然，可坠坳上其巅也。
The steeper it gets to the east, I climb to the end of the cliff to look down. Below is the Shoushen Gorge. To the east is Dongfeng after Caoxi Temple. In the past, I climbed from the bottom of the cliff. Now I climb to the top of the cliff. The Dongfeng area rises side by side from the bottom of the cliff, with a distance of more than one zhang. There is a mountain range connecting, like a thumb, you can climb over the depression and climb to the top of the mountain.
