The frog lived down in a well where there was all he had to live. One day, a softshelled turtle came by and told him about the sea. 'The sea? Hah! It's paradise in here. Nothing can be better than this well. Why don't you come down and share my joy?' The turtle tried, and failed as the mouth of the well was too small. 'Why don't you go see the sea instead? During Yu the Great's reign, there was flooding for nine out of ten years, yet the sea barely grew an inch. During Tang of Shang's reign, droughts were experienced in seven out of eight years, yet the sea hardly shrank. Being unaffected by such disasters is the joy of living in the sea.' Moral: Some ignorant people know nothing aside from their own world.From Wikipedia article on the fable.
