《水经注·卷九》
寺院旁边杂树疏疏落落，有一洼石井泉，约莫丈余见方，一涨清泉平静不波，住在山上的人都靠这泉水饮用。
寺左右杂树疏颁，有一石泉，方丈余，清水湛然，常无增减，山居者资以给饮。
Beside the temple there were various sparse trees, and a stone well spring, about a zhang wide and long, with clear water that was still and unruffled. The people who lived in the mountains relied on this spring for drinking water.
