I'm looking for books that can better interpret the inner meaning of Journey to the West.

Journey to the West was a famous classical novel. It told the story of Sun Wukong, Zhu Bajie, Monk Sand, and Tang Sanzang (or the "Journey to the West") who went to India to retrieve Buddhist scriptures after 81 difficulties. This novel contained a rich cultural content, and the inner meaning was relatively profound. Sun Wukong, as the protagonist, represented the power and freedom of human nature. He had extraordinary abilities, but he was constantly restricted and restricted. He needed to work hard and struggle to get rid of these restrictions and achieve his freedom. Zhu Bajie represented the greed and laziness of human nature. He longed for wealth and enjoyment, but he was constantly addicted to his own enjoyment and lacked self-discipline and self-control. Monk Sand represented the loneliness and helplessness of human nature. Although he was a good person, he was often misunderstood and hurt by others, lacking love and support. Tang Sanzang represented the compassion and wisdom of human nature. He taught Sun Wukong and others to be kind and upright, to pursue truth and wisdom, but they were often misunderstood and attacked by others. The inner meaning of Journey to the West was very rich, involving human nature, society, morality, faith and many other aspects. Reading this novel can help us better understand the nature of human nature and the way human society works. At the same time, it can also make us more aware of our shortcomings and constantly strive to improve ourselves.
