Whose name is the stone monkey on the journey to the west?

Wu Cheng'en

Example 1: Monkey King: While playing with a group of monkeys, I stumbled upon water curtain cave. The monkeys agreed that whoever could enter water curtain cave to find out would be crowned king. The stone monkey bravely jumped into the waterfall to explore the cave and led a group of monkeys to the cave, which was called the monkey king.

Example 2: Bi Marvin: Wukong borrowed a "golden cudgel" from the East Sea Dragon King, and the Dragon King reported it to the Jade Emperor. The Jade Emperor sent someone to trick him into the sky and gave him a "Bi Marvin", a small horse herding official.

Example 3: "the Monkey King": When Wukong learned that "Bi" was only a small official who looked after horses for others, he was very angry when he learned that he had been cheated. He returned to Huaguoshan and raised the banner of "the Monkey King".
