《水经注·卷二十二》
洧水又往东流，汇合了沥滴泉水。此水从深溪旁流出，从一丈多高的岩头散流而下，所以文人把它称为沥滴泉，南流注入洧水。
洧水又东会沥滴泉，水出深溪之侧，泉流丈余，悬水散注。故世士以沥滴称，南流入洧水也。
Wei Shui flows east again and merges with Lidi Spring Water. This water flows out from the deep stream, and it flows down from the top of a 10-foot-high rock. Therefore, literati call it Lidi Spring, which flows south and merges with Weishui.
