Does the turn signal at the entrance of the barber shop belong to property management?

The turn signal at the entrance of the barber shop is not in charge of things.

The origin of lanterns:

Since then, the hairdresser has officially played the brand of surgeon and chose tricolor column as his signboard for practicing medicine and cutting hair. Red in the tricolor column represents arteries, blue represents veins, and white represents gauze. 1745, King George II ordered the establishment of the Royal College of Surgeons. The surgeon was separated from the barber shop, but the tricolor column in front of the barber shop has been used.

In the Middle Ages, there was a popular saying in western Europe: people were sick mainly because of the imbalance of various elements in their bodies. As long as additional "elements" are introduced, they will be restored. Blood is considered as the most easily derived "element", so Europeans think that "bloodletting is the beginning of rehabilitation."

However, the doctor thought that this was something done by inferior people, refused to bleed automatically and manually, and entrusted the barber to do it, so the barber became an amateur surgeon. With the approval of the King of England, the Federation of Barbers and Surgeons was established and a grand ceremony was held for this purpose. The king personally handed the approval letter to Vickery, president of the Federation.

Barbershops all over the world think this style is beautiful and eye-catching, so they follow suit. Barbershops in China also follow this decoration as the only sign of barbershops. Because of the need to attract customers, the pillars at the entrance of the barber shop are not necessarily red, blue and white.
