What Is a China Hand?

My family was in a camp. My grandfather did looting. That was his big thing. But as sort of a visitor, I don't mean it like that. He was the liberated camp. Anyways, it has been a place. Listen, we're not trying to hands. What did it? So, a China hand is, they used to be like a kind of a guy, like a China hand. Now China hand is sort of a shorthand for, excuse me, hand. It's like for like a dumb fucking asshole who's like always like, yes, like G means this when he's doing this. Oh, I hate those guys. We're not those guys.
