Once upon a time, there was an old man called Yugong. There were two mountains near his house. They were so big that it took people a long time to walk to the other side. To deal with this problem, Yugong decided to move the mountains. So his family worked day after day, year after year. Finally, their spirit moved the god. Then the god took the mountains away.
This story tells us that we should never give up when we meet problems.
