In Simplified Chinese, both 著名 (zhùmíng) and 闻名 (wénmíng) can be translated as "famous" or "well-known" in English, but they are used in slightly different contexts.

著名 (zhùmíng) is used to describe someone or something that is famous or renowned for their achievements, talents, or qualities. It is often used to describe people, places, or things that have gained widespread recognition or reputation for being outstanding in a particular field. For example:
- 这位画家是一位著名的艺术家。 (zhè wèi huàjiā shì yí wèi zhùmíng de yìshùjiā) - This painter is a famous artist.

闻名 (wénmíng), on the other hand, is used to describe someone or something that is well-known or famous due to being widely heard of or talked about. It is often used to describe people, places, or things that have become famous or notorious through word of mouth or media coverage. For example:
- 这个城市因为美食而闻名。 (zhège chéngshì yīnwèi měishí ér wénmíng) - This city is famous for its cuisine.

In summary, while both 著名 and 闻名 can be translated as "famous" in English, 著名 is more commonly used to describe someone or something famous for their achievements or qualities, while 闻名 is used to describe someone or something famous due to widespread recognition or reputation.
