In Western culture, we often rely on advertising, expert reviews, or individual online ratings (like on Yelp or Google). While these exist in China, 口碑 (kǒubēi) holds a deeper cultural weight. It is rooted in China's collectivist society, where group consensus and social harmony are highly valued. A good 口碑 is seen as more authentic and trustworthy than any form of official promotion or 宣传 (xuānchuán), which is often viewed with skepticism. It's the “real story” shared among friends, family, and colleagues. For a business, a positive 口碑 can lead to immense success, while a negative one can be devastating. This is because 口碑 is directly tied to trust and social proof. A decision (like which restaurant to choose or which doctor to see) is often validated by the positive experiences of the community. Compared to the Western concept of “reputation,” 口碑 is specifically about the public's user/consumer experience and is spread orally or through community channels. A Western company might have a “reputation” for being innovative or financially stable, which is a different concept. 口碑 is what the masses say about their direct experience with you.
口碑 is an extremely common and important word in modern daily life.
The connotation is usually neutral until modified by an adjective, such as 好 (hǎo) for good, or 差 (chà) for bad.
