Chinese Opera in Nanjing

Kun chu is a type of Chinese opera that is quite popular in Nanjing and the surrounding area so there's a theater. And it's basically a musical form of theater. So they are singing and they're singing in ancient Chinese. When I say song, I mean I really don't know what to compare it to because it doesn't sound like any other music that I've ever heard before. Like, we shall, we all bow.
