Origin: Combined from the ancient symbol for cowrie shell money (贝) to indicate value/finance, paired with 兼 (to hold concurrently) to provide the sound and a hint of accumulating multiple things at once.

Semantic Evolution: Originally referred to commercial gains and profits involving cowrie shells, expanding in modern Mandarin to cover all forms of earning money, wages, and advantageous outcomes.

• Shells were used as ancient Chinese currency, which is why financial terms frequently feature the 贝 radical.
