It's not that a 60-square-meter storefront can't open a beauty salon, but that your area doesn't meet the requirements of opening a brand franchise store.
This is mainly because the franchise brands plan their stores according to a standard when setting the store area, and this standard is to ensure the integrity and sound mechanism of the beauty salon as a whole, which is also the basis of the beauty salon's profit.
If the store area is not enough, it will inevitably destroy the integrity of the beauty salon and cannot provide a strong guarantee for its operation.
