There should be more than 70 square meters for so many tables. According to the table for four, this is almost the area. Depends on how much you put in. My classmate joined an 80-square-meter hot pot, which is about 10 table. Spending 4000 yuan a day, net profit 1.08. This is the profit of the first half and the second half. But it also depends on where you drive, sometimes it has a lot to do with the location. It is also related to its own operations. Can't generalize!
