In year 3010 on the fictional Goat Calendar, the ancestor of the goat clan, Ruan Mianmian (or Old Mandy), arrives at Green Green Grassland to escape the wolves. The goats built a tall iron gate outside their village and called it 'Goat Village'. This leaves the wolves to try and break in any way they can. One day, a wolf suggests that they exercise, get thin and squeeze through the bars. So the wolf ancestor, Wu Dalang, manages to get through after long exercising, only to die after swallowing a huge rock covered in wool, mistaking it for a big sheep. After this incident, the wolves learned not to make the goats of Green Green Grassland angry, for there will be consequences.
