Is There a Reference Grammar?

In Japanese, if you use passives in Japanese, that's because the guy who actually did the action is doing something bad. But I didn't want to necessarily put that negative connotation on it. It could be positive or but there is a connotation. Chinese passives can have sort of a somewhat negative connotation, but it's sort of a weak connotation there. So that's an interesting that you have the two different types of passives. You have the implicit and the explicit if I'm looking at the right thing. And some kind of just a way to reference grammar because it's that curgent.
