陂湖（彼眉反桂苑珠叢云澤鄣也謂以土壅鄣水也案草澤有水曰陂下音胡說文大陂曰湖案吳越有青草洞庭皆大湖也）。

Pools and lakes (陂湖: [first character pronounced] bi-mei fan [bēi]. The Guiyuan zhucong says: "A marshy barrier," meaning that earth is piled up to stem and hold back water. Note that when there is water in a grassy marsh it is called a bei [pool]. The lower character is pronounced hu. The Shuowen says: "A large bei is called a hu [lake]." Note that in Wu and Yue there are Qingcao and Dongting, both of which are large lakes).
