Spinning Barber's Pole - 4K 影片檔

That spinning, striped sign outside a barbershop is called a barber's pole, a traditional symbol representing the barber trade's history. The red and white (and often blue in the US) stripes symbolize blood and bandages from when barbers performed medical procedures like bloodletting during medieval times. They would hang blood-soaked bandages on a pole to dry; the wind would twist them into a spiral.
