The origin of the banana fan can be traced back to the Journey to the West. In the book, the banana fan is the magic weapon of Princess Iron Fan, which is the leaf of the essence of Tai Yin that grows in the back of Kunlun Mountain at the time of the beginning of heaven and earth and chaos. This fan has the magical power to extinguish the fire air, and if it is fanned at a person, it can make the person float for 84,000 miles before resting the yin wind. In the story of "Journey to the West", the four members of the Tang Monk and his disciples encountered difficulties in the Flaming Mountain and needed to borrow the banana fan to cross the mountain. In addition, banana fans have a certain history in ancient China, first appearing in the Warring States period, when some people used bamboo and banana leaves to make fans to dissipate heat. With the passage of time, the banana fan gradually became a common household item, widely spread in folklore.
