still waters, river in Jiangsu
泖 centers on calm, still water, often used in the name of a river in Jiangsu. The idea is of a placid body of water without strong currents.
泖 combines the water radical 氵 with 卯, which likely contributes the sound. The character is used for still waters and a specific river name.
The water radical 氵 beside 卯 suggests a calm, still pool. Imagine a quiet pond where the water barely moves, reflecting the shape of 卯 on its surface.
For ボウ, picture a still pond shaped like a bow: bow -> ボウ, and the water is so calm it forms a perfect arc.
