《徐霞客游记·粤西游日记二》
这座山峰在白面山的西面，高处赶不上白面山，可耸立着如同竖起的标杆和层层相叠的高塔，路上的人都指点读书岩在这座山峰的半腰间，竟然望着它快步赶去。
其峰在白面之西，高不及白面，而耸立如建标累塔，途人俱指读书岩在其半，竟望之而趋。
This mountain peak is on the west side of Baimian Mountain, its height is not as good as Baimian Mountain, but it stands tall like an erected flagpole and a towering pagoda. People on the road all pointed out that Shudulingyan is halfway up this mountain peak, and they went there at a fast pace.
