marketing, sell, trade
販 centers on the exchange of goods for money: selling, marketing, and trading. The core idea is moving items from seller to buyer in a commercial transaction.
販 combines 貝 (shell, used as currency in ancient times) with 反, which likely contributes the sound and may suggest the idea of returning or exchanging. Together they express selling or trading goods for money.
The left side 貝 represents money (shells), and the right side 反 looks like a hand exchanging something. Picture a hand passing goods in return for shells: selling and trading.
For ハン, imagine a hand (ハン sounds like 'hand' without the 'd') passing shells in a busy market: hand -> ハン, and the hand is selling goods.
