优惠 (yōu huì) is a noun meaning 'discount' or 'preferential treatment' — something offered at a reduced price or with special benefits to attract customers or reward loyalty. The character 优 (yōu) means 'superior' or 'excellent', while 惠 (huì) carries meanings of 'favor', 'benefit', or 'kindness'. Together, they convey the idea of an advantageous or favorable condition granted to someone — not just lower prices, but also perks like free shipping, bonus gifts, or priority service.

This word appears frequently in shopping, dining, travel, and membership contexts. It’s neutral in register and widely used in both spoken and written Chinese — from store signs ('全场优惠') to app notifications ('会员专享优惠'). Unlike informal slang terms like 打折 (dǎ zhé), 优惠 feels slightly more formal and comprehensive, often implying a package of benefits rather than a simple percentage off.
