《水经注·卷二十》
丹水从仓野又往东流经兔和山。《春秋》所说的左师驻扎在兔和，右师驻扎在仓野，指的就是这两个地方。
丹水自仓野，又东历兔和山，即春秋所谓左师军于兔和，右师军于仓野者也。
The Danshui River flows eastward from Cangye through Tuhe Mountain. The Left Master mentioned in Spring and Autumn Annals was stationed in Tuhe, and the Right Master was stationed in Cangye, both of which refer to these two places.
