《徐霞客游记·江右游日记十》
越过岭往南下行二里，到达谷底，有两条小溪，一条从东北来，一条从西北来，汇合后流往南。
逾岭南下二里，至坑底，有小溪，一自东北，一自西北，会而南。
Cross the ridge and go down to the south for two li. When you reach the bottom of the valley, there are two small streams, one coming from the northeast and the other from the northwest. When they merge, they flow south.
