there is a booth fee for the stalls in Wuyue Square in Haikou. There must be a management system for setting up a stall in the square, or there must be management personnel on the spot, including the sanitation situation on the square after the stall is over, and the management personnel will arrange personnel to clean it, so these things will cost money, so it is necessary to pay some booth fees for setting up a stall in the square.
