Fortune-telling Honghai _ What does Fortune-telling Honghai mean?

What kind of social reality did the text of The Journey to the West's war between the Monkey King and Hong Haier reflect at that time?

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.
