Statement 1: During the French Revolution, there was a barber shop, which was the stronghold of revolutionaries. Once, the main leader of a revolutionary party escaped from the chase under the cover of a barber. After the victory of the revolution, in recognition of their achievements, they were chartered to use the red, white and blue national flag as a symbol, which gradually evolved into the later flower-turning downlight, and countries followed suit and became the symbol of international barber shops.

Statement 2: Walking in the street, you will see a strange barber shop sign. In Japan, red, white and blue candy bar signs can be seen everywhere. But what does it symbolize, you know? When it comes to red, white and blue, people immediately think of the French flag. But this symbol does not symbolize the ideal of freedom, equality and fraternity like the tricolor flag, but red represents arteries, blue represents veins and white represents bandages. It is said that this international symbol was designed by French man Jannack in 1540.

Then, why do barbershops use arteries, veins and bandages as signs? That's because before the development of modern medicine, hairdressers were often part-time surgeons. They could treat some surgical diseases such as fractures, dislocations and falls, so they took it as a symbol.

Statement 3: It consists of three ribbons: blue, red and white. There were no professional doctors in medieval Europe. Common diseases are treated by bloodletting therapy, and the barber acts as a bloodletting staff. Red represents arteries, blue represents veins and white represents bandages. As a sign, it is equivalent to hanging a wine banner at the entrance of the hotel. Later generations have inheritance, but the content is different.
