Why are there red, blue and white light boxes hanging outside the hair salon?

There are people here who can help you stop the bleeding and dress the wound. Since ancient times, many enterprises have their own special signs. For example, a wine seller hung a wine lid at the door of the store. People will know that this is a bar. No matter what they sell, as long as they stir up a big piece of cloth at the door and write a word on it as a representative, people will have an established concept and know the business scope of the store. When people see a small light box with red, blue and white colors spinning in front of the store, they will know that it is a barber shop. People rarely ask why there is such a design. In fact, when asked, it is estimated that not many people will give an accurate answer. Today, let's tell you why there are three colored light boxes in front of the barber shop. My hair has been white all these years.

The story began in ancient Greece in the 5th century BC, when barbershops appeared and opened to the public. At that time, most hairdressers were part-time priests, because in the eyes of people at that time, barbershops were to remove unclean and unnecessary things from the human body. Of course, such a sacred thing must be done by a priest. In the Middle Ages, there was a great need for doctors in society, so the barber with the barber knife was also a part-time doctor. Of course, doctors at that time basically had only one treatment, and that was bloodletting. In people's minds at that time, people were sick because there were unclean things in their blood. It would be better if unclean blood was discharged. Therefore, it is easy for a barber to bleed with a knife.

At that time, a French soldier was injured in the chest and was in a coma for several days and nights. When the doctor sees this situation, as long as there is no bleeding, he will immediately receive bloodletting treatment. After bleeding twice in succession, the soldier miraculously woke up and finally recovered. Some people were cured, others died of serious illness. For example, George Washington, the father of the United States, led the United States to victory in the War of Independence, and finally established a new country and became the first president. Even the president can't escape the fate of disease and bloodshed. Unfortunately, after repeated bleeding, he failed to cure his own death.

What is the relationship between the barber's ability as a doctor and the bleeding patient and the tricolor rotating object at the door of the barber shop? The stripes of these three colors are red, white and blue. In the western concept, red represents blood, white represents bandages and blue represents blood vessels. Therefore, this three-color light box means that someone here can bleed and bandage your blood vessels. Of course, it turns out that bloodletting is extremely unscientific, so now there is no barber shop in the east and west that can be used as a hospital to treat patients, and no barber dares to bloodletting patients privately. The three-color light box still exists because this object has become the representative symbol of barber shop in people's eyes, that's all.
