I've often heard about the blue shop recently. What is the blue shop?

Generally speaking, the blue shop is a courier service. For example, I bought something online, and the courier put it directly in the nearby blue shop, and then informed me to pick it up by SMS, which can improve the delivery efficiency. I like this way very much. I only write the address where I shop in the community, so as to avoid the exposure of the specific address and protect my personal information. You are satisfied with my answer. Take it.
