买 (mǎi) is an ancient Chinese character. Its traditional form is 買, which shows 网 (wǎng, "net") over 贝 (bèi, "cowrie shell"). Cowrie shells were used as currency in ancient China, so the image of a net full of shells evoked the act of acquiring goods through trade. Over centuries the character was simplified to its modern form 买.

China has one of the world's most vibrant shopping cultures, both offline and online. Platforms like Taobao and JD.com make 买 an everyday word in digital life. Watch out for the near-homophone 卖 (mài, "to sell") — the tones and meanings are opposite, a classic false-friend trap for learners. A handy market phrase: 多少钱？(Duōshao qián? "How much does it cost?") naturally pairs with 买.
