He was originally the Tianpeng Marshal of Heaven, in charge of Tianhe's 100,000 sailors, and was majestic. But because of drunken teasing with Chang'e, he was demoted to the mortal world and was mistakenly reborn into a pig's womb, turning into a pig-headed human body.
He has a cute and honest personality, is greedy for food, sleepiness and money, and often makes jokes just for a bite of food. On the way to learn the scriptures, when encountering difficulties, he shouted to break up and return to Gao Laozhuang, which made people laugh and cry. But he also has a kind and affectionate side, and is loyal to his master Tang Seng. Although he occasionally has a little temper with his senior brother Sun Wukong, he can fight side by side at critical moments.
