what is jin gu bang that SUN WUKONG take?

Jin Gu Bang, also known as the "Ruyi Jingu Bang" or simply the "Magic Staff," is a legendary weapon wielded by the mythical character Sun Wukong in the Chinese classical novel "Journey to the West." Sun Wukong, also known as the Monkey King, is a central figure in this epic tale.

The Jin Gu Bang is a magical, shape-shifting staff that Sun Wukong acquires from the Dragon King of the East Sea's underwater treasury. This staff is said to be incredibly heavy and dense, capable of expanding or shrinking at Sun Wukong's command. Despite its small appearance when not in use, the staff can grow to immense sizes, making it a formidable and versatile weapon.

In "Journey to the West," Sun Wukong uses the Jin Gu Bang to perform extraordinary feats, such as defeating powerful foes, creating havoc in heaven, and aiding the monk Xuanzang on their journey to retrieve Buddhist scriptures. The staff symbolizes Sun Wukong's strength, agility, and magical abilities, making it an iconic element of Chinese mythology and literature.
