《徐霞客游记·江右游日记六》
原先，从百顺铺往西到周家隘的路上，见到一条小水西流，我以为它是流入南溪中的，等登上分水岭，才知道它仍是往北流入东溪中的。
先是自百顺西至周家隘，有小水西流，余以为入南溪者；及登分水，而后知犹北入东溪者也。
Previously, on the road from Baishunpu west to Zhoujia'ai, I had seen a small river flowing west, and I thought it flowed into Nanxi River. After ascending Fenshuiling, I learned that it actually flowed north into Dongxi River.
