《徐霞客游记·粤西游日记三十八》
西面一列群峰蜿蜿蜒蜒，它南北两面向东突出来的支峰，既好像是左右臂，又有当中一条支脉下延独自耸起成为石峰，而下面的官署就紧靠着它，囤子建在上边，三面峻峭陡削，唯有南面有山坳可以上登。
盖西界群峰蜿蜒，其南北两支东突者，既若左右臂，又有一支中下特起为石峰，而下署倚之，囤结于上，三面峭削，惟南面有坳可登。
On the west is a row of peaks winding and winding, its north and south sides protruding eastward branches, which seem to be left and right arms, and there is a branch in the middle which alone rises to become a stone peak, and the government office below is close to it, and the fortress is built on top, with three sides steep and steep, only the south has a mountain pass to ascend.
