I lived and grew up in Kaifeng, and I didn't feel there was a black shop in Kaifeng. Besides, although the Gulou night market is expensive, it is all priced uniformly. Take a closer look for yourself. How can a clearly marked price be called a pit? You don't eat other people's food, and they won't ask for money with a knife around your neck? I want to ask where you come from. The consumption level in Kaifeng is low enough, but it is still too expensive. Don't go out to play without money, no one at home will lie to you.
