牛窪（烏瓜反淮南子云牛蹄之窪不生鱣鮪廣雅窪下也古今正字從穴洼聲洼音同上）。

Cattle-foot hollow (wū + guā fanqie. The Huainanzi states: 'A hollow made by a bull's hoof does not breed sturgeon or tuna.' The Guangya states: 'Wā means low-lying.' The Gujin zhengzi states it takes 'cave' with wā as its phonetic, pronounced the same as above).
