A long time ago, there were three little pig spirits. They were the big pig spirit Gongsun Yue, the second pig spirit Se Wuji, and the little pig spirit Butterfly.
When they grew up, they had to separate their families, so they each found a good place in Yinchuan Butterfly Valley and built a new house.
Big Pig and Er Zhu have a very good relationship and love each other. Originally, they planned to build just one house and live together, but they were strongly opposed by Little Pig Butterfly, who had a crush on Big Pig Gongsun Yue.
