What is the future market model? Which is more promising than a vegetarian restaurant?

Although I don't know what the market model is, at present, the houses built by builders are all shops on the/kloc-0 floor, and some shopping buildings also sell things. However, shops need crowded places to sell things, because there is no business or anything when it is cold and cheerless. The main difference between online and offline is that online faces the whole country and offline faces customers in a nearby area. So, let's sell things together. . On the other hand, I also want to know, if there is a building, for example, called Kuaibu, you can sell everything, and there is also an app, which is the app of this "Kuaibu" building, which sells the goods in it, so that you can get the reputation of this building off the line, let the nearby counties and cities know about it, and then do some advertisements on the Internet to know that this app is. Shopping nearby can go to the "quick purchase" building, shopping far away can be bought in the app, or investment can be set up on the app, but the head office must be located in the "quick purchase" building, so that the "quick purchase" building may be a symbol of prosperity in that area in the future.

Of course, this is my fantasy. . After all, the house is hard to build now, but no one can afford it. I really don't know who it is for.
