Street stall is a relatively simple way of doing business. If street stall is very profitable, it is obviously an unbelievable topic. As we all know, investment and income are directly proportional, just as Einstein's special relativity and general relativity mentioned that the transformation between substances is always equal, and it is impossible to have more or less. The investment in the stall is very small. Assuming that you can earn a lot of money with very little investment, who will make a bigger investment?

So street vendors can maintain a family's life, and they need to be able to gradually improve the economy of a region. It is absolutely impossible to make a person rich overnight, let alone become a rich man from now on. Investment and making money are in direct proportion, which is the same in any region and any economic situation. Therefore, we should have a correct understanding of street vendors, never exaggerate, and never be too blind, so that we can make the right choice.
