What kind of social reality is reflected in the section of The Journey to the West where the Monkey King fights Hong Haier?

The Journey to the West observed the magical world in his works with a strong spirit of joining the WTO, and exposed and criticized the social reality. In fact, the exploitation of the land of the mountain gods in this paper alludes to the reality that the powerful seize one side, plunder the people and make them miserable. The author mocked "You Mao who was not good at fortune-telling", mocked that the prodigal son's "red million" turned into "red hundred thousand", and satirized the indifference of his relatives who didn't go home for three years and didn't date each other, which also reflected the author's attitude towards the world.
