I often see Tsingtao Beer logo on billboards. Is the shop owner cooperating with the beer company or something?

It is a cooperation between the store and the beer company. If the store owner wants to make a billboard, the beer company will help make it, usually for free.

But there is usually a cooperation agreement,,, but it seems that Harbin Beer is a little better, and it also provides display cabinets.

Supplement: Yes, that’s it. They do the store signs for free, but there is usually an agreement, that is, how much do you sell in a month, or how much do you sell in a year? If If your sales volume is relatively large, you can also ask them to pay an admission fee. It's all like this.
