Yes ~ I'm from Qingdao, Shandong. Our supermarket once tried to spend too much money, but later consumers thought it was too much trouble to change money, so the supermarket used rounding method. In order to give consumers more convenience, some supermarkets even omit nine points. In fact, it is also for the convenience of consumers, and has nothing to do with the existence of money.

The existence of money depends on banks and national policies, not on supermarkets and other places ~
