I remember there seems to be a car selling ice cream hamburgers in the car abroad. I wonder if this can be done in China? Is it allowed by law?

You want to open a similar store. In fact, there have been similar shops in our country (like convenience dining cars), but the difference with foreign countries is that they are immovable. There is no such model in China, and people have not yet developed this habit. Have you ever seen a dining car driving slowly on the road, and a passerby shouted: Hey, boss, have a coke and a hamburger!

Legally, you don't have a business license or a health permit. So it will be caught by the urban management.

But your idea is still great. A similar mobile dining car appeared during the Olympic Games. But this is not common. The most important thing to do is to change people's habits. Very that! But there are also great business opportunities. Not bad.
