Zuijin

Zuijin is a Chinese word that means "recently" or "lately". It is used to talk about things that have happened, or things that people have noticed, within a certain time period.

Imagine that you have a friend who just got a new toy. You might ask them, "zuijin ni de wanju shi shenme?" This means "What's your new toy lately?"

Likewise, if someone asks you how you've been doing, you might say "wo zuijin hen hao", which means "I've been doing well recently".

So basically, zuijin is a way to talk about things that have happened in the past few days or weeks. It's a useful word to know if you're trying to have a conversation in Chinese about current events or recent experiences.
