I believe that everyone will frequent the barbershop, then you must have found that there will be a rotating roller at the entrance of each barbershop. Is it really to attract everyone's attention? It's hard to think that this is actually related to surgery.
In the past in Europe, people's medical awareness was relatively weak, and most diseases could be treated in one way, that is, bloodletting. With the passage of time, more and more people will choose this way to treat diseases, but for doctors, it is a more troublesome thing, after all, people's small diseases, the first thing that comes to mind is bloodletting.
The barbershop had scissors, blades and other tools, so the barbershop at that time took over the job. So the barber became an amateur surgeon. In order to advertise that their shop can bleed, the barbershop will tie the bandage that has been bandaged after the bloodletting to a stick and then place it in front of the store, so that there are the first red and white stripes.
Later, there was an extra blue, some people said that blue represents the vein, so red represents the artery, and white represents the bandage.
Another theory is that this rotating roller is related to the French Revolution, it is said that the owner of a barbershop protected the revolutionaries at that time, and later the success of the French Revolution, in order to recognize the support and contribution of barber workers to the Revolution, in front of the barbershop installed a rotating roller representing the french flag red, white, blue three colors, so other barbershops have followed suit, until now.
