This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
鄮 is a rare character combining 貿 (trade) and ⻏ (village/city). The exact historical development is uncertain, but it likely originally referred to a place name.
The left side 貿 suggests trade or exchange, and the right side ⻏ suggests a place. Imagine an ancient trading post or market town, but remember that the actual meaning is unclear.
For ボウ, imagine a bow (as in bow and arrow) being traded at the market town: bow -> ボウ, and the trade happens at the place represented by 鄮.
