#交易手续费揭秘

In front of the bank counter, Old Zhang clutched the crumpled remittance slip, his fingers slightly trembling. The fee section showed "2%", and he calculated it three times, still finding it thirty yuan more than last year. The financial manager at the adjacent window was animatedly introducing the "Supreme VIP Fee Waiver Package" to a suited customer, and the reflection on the glass made Old Zhang squint.

Back home, he dug out the remittance records sent by his son from abroad, only to find that each transaction had been stripped of two layers of fees — once here, and once there. During a video call that night, his son smiled and said: "Dad, we now use blockchain for transfers, and the fee is just a few dimes." But Old Zhang stared at the complicated QR code on his phone, ultimately just sighing. The next day, he carried cash and took a two-hour bus ride to his relative's house in the suburbs, personally stuffing his nephew's backpack with his tuition. On the way back, the bus's QR code scanner beeped, deducting another fifty cents as a processing fee.
