***Hanging refrigerator in my feeling is still not very profitable, first of all, the place is a problem, and then inside the drink or food,

Because of the refrigerator volume, there will not be too much, and food and drink hygiene and shelf life need to be often to manage, so the cost of labor will be very high, if ****Hanging refrigerator dispersion is high, then the labor will be laborious, the item replenishment is also problematic. That's why I'm not too optimistic about the development of **** enjoy refrigerators. Of course, it is possible that I have a problem with the eyes, it is also possible that this project can be fruitful, I hope you do more market research, do not blindly on the horse, I hope you succeed.
