The conspiracy theory of Journey to the West was an interpretation of the Chinese classic novel Journey to the West, which believed that there were some elements of politics, conspiracy, and conflict of interests. This interpretation mainly appeared in some online literature, fantasy novels, and other works, but it was not widely recognized. In Journey to the West, some plots were considered to be the embodiment of political conspiracy, such as the struggle between Sun Wukong, the Bull Demon King, and Princess Iron Fan. There might be some political interference behind it. In addition, there were also some seemingly accidental events that might have some kind of arrangement and purpose behind them. However, it should be noted that the interpretation of the conspiracy theory of Journey to the West did not conform to the plot and content of the original novel. Although there were some political elements in the novel, most of the plot described the adventures and growth of the main characters such as Sun Wukong, as well as their friendship and unity with the people. Therefore, the interpretation of the conspiracy theory of Journey to the West should be regarded as an interpretation of a fictional novel rather than a conspiracy theory of real historical events.
