The story of Yu Gong
Once upon a time, there was an old man named Yu Gong. Two big mountains stood in front of his house. It was very difficult for him and his family to go out.
So Yu Gong decided to move the mountains. His family all agreed to help him. Every day, they dug the mountains and carried the earth and stones to the far sea.
A clever man laughed at him, saying he was too old to move the mountains. But Yu Gong said his family would keep doing the work after he died.
Finally, a god was moved by Yu Gong's spirit. He sent two gods to take the two mountains away.
