When the Monkey King first arrived in heaven, he was given an official position-Bi Marvin. Later, because he felt cheated, he went down to heaven and returned to Huaguoshan, calling himself the Great Sage of Heaven and forcing Heaven to recognize the title. Later, he made a scene in the Heavenly Palace, disturbed the flat peach pageant of the Queen Mother, stole the old gentleman's elixir, defeated 100,000 heavenly generals, overreached himself against the Tathagata, and was crushed under the Five Elements Mountain for more than 500 years.
