SIMILAR WORDS - Vietnamese and Mandarin

On my most recent trip to Vietnam I discovered chú ý

It’s very similar to a word in Mandarin, any guesses from any of our Mandarin speakers?

HINT || it’s a useful word you normally see on signs and outside when travelling from A to B.

EXTRA HINT || it’s also almost exactly the same in Japanese and Korean too!
