In Journey to the West, the story of the Banana Fan tells the story of the difficulties and challenges that Sun Wukong, Zhu Bajie, and Monk Sand encountered on their way to the scriptures, and how they overcame these difficulties through wisdom and courage. The story was summarized as follows: Sun Wukong heard that the banana fan could extinguish the flaming mountain and went to look for it. However, Sun Wukong was surrounded by the Bull Demon King, Princess Iron Fan, and other demons in the Banana Fan's production area, unable to obtain the Banana Fan. When Sun Wukong heard that the Banana Fan had been borrowed by Princess Iron Fan, he went to her Banana Fan Cave to borrow it. However, the Iron Fan Princess not only refused Sun Wukong's request to borrow the fan, but she also broke it down one by one so that Sun Wukong could no longer borrow it. After that, Sun Wukong went to the Flaming Mountain's Flaming Cave to borrow fire, but the sea of fire at the entrance of the Flaming Mountain swallowed everything, and Sun Wukong could not borrow it. When Sun Wukong heard that the owner of the banana fan was the Bull Demon King, the son of Princess Iron Fan, he went to the Bull Demon King's cave to borrow the fan. However, the Bull Demon King gave the banana fan to Princess Iron Fan so that Sun Wukong could no longer borrow it. Sun Wukong had no choice but to go to the origin of the banana fan to look for it. On the way, he met Zhu Bajie and Monk Sand. Together, they finally found the banana fan. However, the banana fan had already been taken away by Princess Iron Fan and they could no longer borrow it. At the end of the story, Sun Wukong used his wisdom and courage to borrow the banana fan from Princess Iron Fan and used it to fan out the Flaming Mountain, solving a big problem on the way to learn the scriptures.
