Folding fan, formerly known as waist fan, originated in the late Han Dynasty and was once a vassal's pet. In the Jin Dynasty, waist fan, also known as folding fan, has become a common summer appliance for men and women in the upper class. During the Southern and Northern Dynasties, southern scholars often used this thing to enjoy the cool when they went out. The Qing dynasty was a period of great development of folding fans in China, and folding fans were used more frequently among scholars and officials. The fan is not only a tool to create cool breeze, but also a work of art, a symbol of status and interests, and a prop for its social role.
