Perhaps the most famous ancient Chinese fiction is the “Travelling to the West” (西游记). It’s a story about an adventure team of Monk Tang (the master 唐僧), the Monkey King (孙悟空)， the Pig God（猪八戒），and Monk Sha（沙僧），who were in a tough journey to the West (nowadays India) to acquire the Buddhist Bible.
Hereby, piggy wants to highlight one guy in the team, of course it should be the Pig God（猪八戒）. Originally, the Pig God（猪八戒）was the commander of the Navy in heaven. Because he molested the Goddess of Moon (嫦娥), he was punished to go to the folk. Unfortunately, when he descended to the folk, he was a bit nervous and did not watch carefully. He went into a mother piggy. Then, when he came into his next life, he looks like a pig and has to become a monster.
