This still needs to be negotiated with the mall. I think a booth in a more formal shopping mall should have a main brand, not that the mall allows it, but that the average booth is about 30 square meters (not counting the seats next to it). First of all, I am too busy. Secondly, if all the snacks are sold, it will make others feel a little unprofessional, at least I think so (hee hee). However, I have seen a stall selling three different styles of snacks in our shopping mall (large food city) ("xx beef noodles" is the first name, followed by spicy duck neck and fried skewers). I think there is a main course at the door, and it is ok to sell two or three other snacks.
