* * * How to make a profit by enjoying the refrigerator?

* * * In my opinion, enjoying the refrigerator is not very profitable. First of all, location is a problem, and then the drinks or food inside,

Because of the problem of refrigerator volume, it will not be too much, and the hygiene and shelf life of food and beverage need to be managed frequently, so the labor cost will be high. If * * * enjoys the high dispersion of refrigerators, then it is very laborious for people to join the trade union, and replenishment is also a problem. So I am not optimistic about the development of refrigerators. Of course, it is also possible that my vision is wrong, and it is also possible that this project can achieve results. I hope you do more market research and don't blindly put it in. I hope you will succeed.
