Fans have a history of three or four thousand years in China. After thousands of years of evolution, improvement and perfection, it has developed into hundreds of fan families, but it is generally divided into two categories. Flat fan 1 handle (that is, round fan, sunflower fan, wheat straw fan, tracts fan, etc.). ) cannot be folded, and the two folding fans can be folded freely.
Flat fan comes from "obstacle fan" (palm fan) and "bamboo+agility" (fans made of bamboo chips were called "bamboo+agility" in ancient times). During the Warring States, Qin and Han Dynasties, a kind of semi-formal "instant noodles" shaped like a single door, so it was also called "household fan" and became the mainstream of fans at that time.
