Why are there rotating lights in front of the barber shop?

Used to attract customers. It is called hair-turning lamp, also called style, flower-turning downlight, rotating light box, etc. This lamp is foreign. In China, there was a distinction between a haircut and a shave a long time ago, and there was no such thing as "love rat tin foil perm and love rat big wave". Now all the places where hair is done are called hairstyle design, and most of them are from abroad. So is this lamp. Maybe the original lantern just rotates to look better and attract attention in the street. The light in front of the barber shop recently found that my hair has grown again. There were not many codewords every day. When my hair grows out, I fall off and show my scalp. When I was sitting in the sun, I found the sun shining through my hair. I can't help it Bosses are basically bald. Although I don't want to be bald, the size can still be less obvious. Shave your head. At this time, a word rang out in my ear: in fact, this lamp is promising. It is called hair-turning lamp, also called style, flower-turning downlight, rotating light box, etc. This lamp is foreign. Because of hairdressing, it was divided into haircut and shaving in China a long time ago. There is no such thing as "love rat tin foil perm and love rat big wave". Now all the places where hair is done are called hairstyle design, and most of them are from abroad. So is this lamp. Maybe the original lantern just rotates to look better and attract attention in the street.
