According to "In the Garden Magazine", Wan Fan was the earliest fan used in ancient China. As for the folding fan used by modern people, it is also called spreading fan. North Korea paid tribute to China during the Yongle period of the Ming Dynasty. Ming Chengzu liked this kind of fan for its comfort and convenience, so he ordered craftsmen in the palace to copy it. Later, it came from the court and soon became popular all over the country and was widely used.
