Teacher Liu, I saw a blogger say, "Chinese people don't say ni hao." I use it often, so now I'm a little worried.

Don't worry too much. Of course you can say "ni hao." It's just that when acquaintances meet, people often say things like "How have you been lately?"

Then why would the blogger say that?

Titles that go against what most people think are more likely to attract attention and become popular online.

So "not said very often" and "shouldn't be said" are completely different, right?

Exactly. Also, even though native speakers may not use some expressions very often in daily life, those expressions can still help beginners learn correct sentence structures.

I understand. I don't need to keep worrying about whether I sound like a Chinese person. It's more important to learn correct Chinese first.

That's right. When you see claims like this in the future, first think about which situations they apply to. Don't immediately start doubting yourself.
