Where is mother's dialect? It's like being a good boy and drumming.

My mother has never heard of it. Knock, knock, knock, knock. I know. It is Yangzhou dialect. I have a colleague in Yangzhou who likes to say so.

In Princess Pearl, a little eunuch next to the swallow comes from Yangzhou. He always likes to say, "Good boy knocks on the ground, and green onions stir-fry leeks."

Of course, Yangzhou in ancient times was bigger than it is now.
