Hihi my friend, Here is a native Chinese speaker called Lave

And I’m write this just I think this may would be helpful for who’s learning Chinese

Basically just some really small and not organized tips, hope this will help u ~

Oral Chinese

1. Repeating questions phrase twice usually indicates Intensification of tone And it’s widely use.

Example: 

“不会吧” -> Is that possible?
“不会吧不会吧” -> That can't be possiable right?!
ps: this is actually a meme, like a friendly sarcasm...
“不会吧不会吧，2024 年了还真有人不知道可以用ChatGPT写论文？”
-> "No way... it's 2024 and there are still people who don't know that you can write a paper in ChatGPT?"

So… basically u just say it twice with no pause, widely use widely use bro :D

Also if u say in a slow tone even strengthen the feeling.

but I guess this is the same almost in every language hehe.
