Pig Bajie was the Marshal Tian Peng who commanded the 80,000 Water Army of Tianhe in his previous life. He has always admired the beautiful fairy in the dress (a member of Chang 'e, the "Chang 'e" in Journey to the West is the name of all fairies in Yuefu. Not the legendary wife Chang 'e).
All the immortals in The Journey to the West basically borrowed the immortal records of orthodox Taoism. It can be seen from the mention of Pig Bajie in the episode of Gao Lao Zhuang that Tian Peng, the previous life of Pig Bajie, was a sacred sacrifice to the water god Tianhe.
After flirting with the fairy in the dress, provoking the spiritual officer to picket, he overthrew the bullfighting palace and came to the world, but mistakenly threw a pig fetus. Later, enlightened by Guanyin, he became a disciple of Tang Priest. Together with the Monkey King, he protected the Tang Priest from going to the Western Heaven to learn Buddhist scriptures, and was finally appointed as the messenger of the net altar.
Extended data:
The image of Zhu Bajie has the significance of the times. In The Journey to the West, Zhu Bajie is not used to and doesn't like the long-term life of an ascetic monk running around. He was helpless in protecting the monks from getting scriptures.
In case of disaster on the way to the west, he is always the first to retreat, break up, sell luggage, and clamor to go back to Gaolaozhuang to be a son-in-law and farm for a living. This feeling of returning to the land, caring for home and longing for a settled life is also a typical farmer's consciousness and psychology attached to the land for a long time.
It can be said that Pig Bajie is a typical embodiment of working people from rural areas. He has a stubborn and conservative psychology of guarding the formation of the land, which is in opposition to God, Taoism and Buddhism, and shows the life aspirations of ordinary working people.
Pig Bajie is greedy for money, lustful and selfish, which also shows the precipitation of lust and good goods in Ming Dynasty, reflecting the consciousness characteristics of small producers and ordinary citizens at that time, and has the ideological characteristics of that era.
