Excuse me, who is the dialect?

For example, if you knock on your friend's door, he will ask, "Who is it?" , which means "who is it?"

This statement is more common in the north, right? I'm from Ganyu, Lianyungang, and I said the same thing when I asked who it was. Ganyu belonged to Shandong in ancient times, so it is generally spoken in the dialects around Shandong.

I hope the landlord will adopt it ~
