The characters literally combine to mean “foreign remittance” or “converging foreign [money],” which perfectly captures the idea of collecting, exchanging, and transferring international currencies.
In China, 外汇 (wàihuì) is not just a financial term; it's a concept deeply tied to national economic policy and stability. Its significance is very different from the more open “forex” environment in the West. The key difference is control. In the US or Europe, individuals and companies can generally buy and sell foreign currency with few restrictions. In China, the government, through the State Administration of Foreign Exchange (国家外汇管理局, Guójiā Wàihuì Guǎnlǐjú, or SAFE), maintains strict capital controls. For individuals, this is most famously seen in the annual cap on how much foreign currency they can purchase (currently the equivalent of $50,000 USD per person, per year). This control is a strategic policy. It helps prevent massive capital flight, manages the value of the Renminbi (RMB), and ensures financial stability. It also allows China to accumulate the world's largest foreign exchange reserves (外汇储备, wàihuì chǔbèi). These reserves act as a massive safety net for the economy and give China significant influence in global finance. For an ordinary citizen or a foreign visitor, this means exchanging currency is a formal process, always done through official channels like banks, requiring ID and paperwork.

You handle `外汇` transactions to get `外币` cash.
