While `比如` is a functional word, its frequent use points to a common communication style in Chinese culture that values clarity through illustration. It is often considered good practice to follow a general or abstract statement with a concrete example to ensure the listener understands completely. This contrasts with some Western communication styles that might favor staying abstract. In education, business, and daily life, using `比如` is a way of being considerate to your listener. It shows you want to bridge any potential gaps in understanding by providing a tangible reference point. Instead of just saying “I like sports,” a speaker will often clarify, “比如篮球和网球” (“for example, basketball and tennis”), making the conversation more grounded and accessible.
`比如` is an extremely common word used across all registers of speech and writing, from casual chats to formal presentations.
