There are two theories about the appearance of China folding fan. First, it was introduced from Japan or Korea in the Northern Song Dynasty. The reason is that the name folding fan first appeared in the Song Dynasty. Since the Song Dynasty, many documents have pointed out that folding fans were produced in Japan or Korea. Another point is that the waist fans in the Northern and Southern Dynasties were folding fans. According to Zi Tongzhi's note: "The waist fan is attached to the waist, which is now called folding fan". According to the records of waist fan in Liu Xiang Chuan of Southern Qi Dynasty, it is inferred that there were folding fans in Southern Dynasties. In fact, the above two theories are inaccurate and deserve further discussion. First of all, the waist fan appeared before the Southern Dynasties. There are two historical materials to prove it. Jin's "Su Shu Tong Xiong" and "A day's work depends on Cao Gong's utensils and bedding, as well as fans like Wu Fan." Zhang Chang's Old Story of the East Palace: "The Prince needs a painting fan and a bamboo fan for his first visit." According to, Cao Gong refers to Cao Cao in the text. "Waist" was originally the word for waist. When it comes to fan, it means waist fan. This shows that the waist fan was already used in the late Han Dynasty and Wei and Jin Dynasties. Secondly, the name of folding fan did not begin in Song Dynasty. The album contains a set of stones in Wusheng Pavilion. The title is Yuefu Poems, and the fifth of the seventy-five poems at 4: 00 midnight reads: "Fold the fan in the bed to get the wind of the ocean. Light Buddha sleeve makeup, elegant stage. " The folding fan in poetry is a folding fan, which is a name of folding fan in Jin Dynasty. Folding refers not only to overlapping, but also to folding and folding. Release date of Twenty Summer Songs: "Fold, bend." The most commonly used name of folding fan in Song Dynasty is "folding fan", which can be understood as the extension and evolution of the early name "folding fan". Even in the Song Dynasty, folding fans still had many names, which were not uniform. For example, Volume 29 of Jiyun Tieyun is called folding fan, Volume 13 of Koryo Tujing is called folding fan, Volume 1 of Menglianglu is called gathering fan, others are called gathering fan, gathering bone fan and so on. It can be seen that the name of folding fan can be traced back to Jin Dynasty. It can also be seen that folding fans are not imported products, but native products originating in China. In the Northern Song Dynasty, Japanese and Korean tribute folding fans happened to be "exquisite beyond China's reach", so there was a saying of "from guest to guest" in the Song literature. The waist fan mentioned by Jin people is probably a folding fan, because the name folding fan does appear almost at the same time. As a famous historian in the Song and Yuan Dynasties, Hu Sansheng's explanation in "Returning to the Heart and Miscellaneous Knowledge" seems to have some supporting evidence. Referring to Hu's notes and relevant historical materials, we can roughly outline the history of folding fans in China, that is, folding fans, formerly known as waist fans, originated in the late Han Dynasty and were once the pets of princes and adults. In Jin Dynasty, waist fan, also called folding fan, has become a summer appliance for men and women in upper class. During the Southern and Northern Dynasties, southern literati often used it to enjoy the cool. During the Sui and Tang Dynasties, folding fans probably didn't develop much, so that since the Northern Song Dynasty, when exquisite folding fans from Japan and South Korea flowed into China, relatively simple folding fans from China were submerged, which is why historians believe that folding fans were introduced from the Southern Song Dynasty.
