So I guess the guy with the obscured face is a human. Probably one who isn't Chinese since he was stumped by the idiom. Maybe Gaia has to bring in an unbiased human to approve significant actions like this.
Ok, Nanjiang County is a place in China, but I don't think this title is referring to that. It's just a random name the courts gave to describe the land he controls, or will control.
