《水经注·卷十四》
梁河又往南流，有涧于水注入。涧于水发源于东北山，往西南流经土垠县老城东面，往西南流，注入巨梁水。
梁河又南，涧于水注之，水出东北山，西南流径土垠县故城东，西南流入巨梁水。
Liang He continues to flow south, receiving Jian Yu Shui.  Jian Yu Shui originates from the mountain to the northeast, flowing southwest through the east of Tu Ren County’s old city, and then continues to flow southwest to meet Ju Liang Shui.
