In both Western and Chinese cultures, being “famous” means being widely known. However, the flavor of 有名 (yǒumíng) can be slightly different. While it certainly applies to movie stars and singers, it's also frequently used to describe people or places that are respected and have a strong reputation within a specific community or field, not just in the mass media. Think of the difference between a celebrity chef on a reality TV show and a local doctor who is 有名 in your city for their skill and kindness. Both are “famous” in a sense, but the latter reflects a type of community-based reputation that is highly valued in Chinese culture. Being 有名 isn't just about media exposure; it can be about having a good name (好名声 - hǎo míngshēng) that is built over time through skill and contribution. It's less about fleeting “celebrity” and more about established “reputation.”
有名 (yǒumíng) is an extremely common word used in all registers of spoken and written Chinese.
