I flew with this 2 years ago. Looks like a standard boing/airbus from the inside but the sound isolation is so bad, it's very loud inside

Well, if you've managed to create an airliner, starting from not having made one at all before, then the sound isolation would be the most trivial thing to improve in an update.

You sure? C919 didn't start commercial flights until this year (2023)

That was my understanding, too.
